2. Introduction
|
|||
|
|
|||
|
2.1. Supported Devices
|
|||
|
|
|||
|
The following list of PDA's are supported by the Linux USB-Visor module:
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>Handspring Visor (all)
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>Palm USB Devices (all)
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>Sony Clie (all)
|
|||
|
|
|||
|
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
2.2. What's needed?
|
|||
|
|
|||
|
To syncronize your Handspring Visor onto your linux computer, you need to
|
|||
|
configure linux to know how to do the low-level communication with your
|
|||
|
device, and then a a user-space program to do the actual communication with
|
|||
|
the device.
|
|||
|
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
2.3. Linux Distributions
|
|||
|
|
|||
|
Many distibutions now come with kernels pre-configured with appropriate
|
|||
|
support. If you have such a distro, and do not wish to re-compile the kernel,
|
|||
|
then you can probably skip ahead to the Syncronziation Software section. The
|
|||
|
following is an incomplete list of distro's that have support pre-configured:
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>Mandrake 8.2 (or later)
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>Redhat 7.2 (or later)
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>Suse 8.0 (or later)
|
|||
|
|
|||
|
|
|||
|
You may check if your distro already has support by running this command as
|
|||
|
root:
|
|||
|
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|modprobe visor |
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|
|||
|
If the program printed any error messages, then you will need to re-compile
|
|||
|
the kernel with the approriate support. If nothing was printed, it means that
|
|||
|
it was successful, and your distro already provides support.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
3. Configuring the Kernel
|
|||
|
|
|||
|
3.1. Requirements
|
|||
|
|
|||
|
Some obvious things are required, such as a computer, USB ports, Handspring
|
|||
|
Visor (with USB cradle). You should also know how to compile and install
|
|||
|
programs and the kernel. If you do not, you have a few options: learn, get
|
|||
|
your resident expert to help you, or get a distro with everything prepared
|
|||
|
for you.
|
|||
|
|
|||
|
If you don't have a USB controller for your computer, then you need to either
|
|||
|
buy the serial cradle for the Visor (but you wont need this document), or buy
|
|||
|
a USB-capable device for your computer (ie. add-on card or a new
|
|||
|
motherboard).
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
3.2. Kernel Version
|
|||
|
|
|||
|
The linux kernel version v2.4 was the first to have USB support. You can get
|
|||
|
the latest v2.4 kernel from: [ftp://ftp.kernel.org/pub/linux/kernel/v2.4/]
|
|||
|
ftp://ftp.kernel.org/pub/linux/kernel/v2.4/.
|
|||
|
|
|||
|
The USB code has been backported to the v2.2 kernel, starting at version
|
|||
|
v2.2.18. If you must, you should probably be able to follow the same
|
|||
|
instructions with the latest v2.2 kernel
|
|||
|
|
|||
|
Now would be a good time to download the latest kernel, and configure things
|
|||
|
to your desire. The following has the instructions you need to configure USB.
|
|||
|
|
|||
|
If you have already have compiled and installed the kernel, you should not
|
|||
|
need to reboot! All we need to do is to compile and install the appropriate
|
|||
|
modules, and we will be all set.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
3.3. USB Controller Type
|
|||
|
|
|||
|
The first thing to do is o determine which type of USB host controller you
|
|||
|
have. The USB host controller is the hardware in your computer which handles
|
|||
|
USB input/output.
|
|||
|
|
|||
|
Motherboards based on Intel chipsets, are typically UHCI controllers. Most
|
|||
|
addon cards are OHCI controllers. You can determine the type of USB hardware
|
|||
|
available by using, as root, the following command:
|
|||
|
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|lspci -v |
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|
|||
|
If you see an entry like:
|
|||
|
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|USB Controller: ...... |
|
|||
|
|Flags: ..... |
|
|||
|
|I/O ports at .... |
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|
|||
|
Then you have a UHCI based controller. If you see an entry like:
|
|||
|
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|USB Controller: ..... |
|
|||
|
|Flags: .... |
|
|||
|
|Memory at ..... |
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|
|||
|
Then you have a OHCI based controller. You could refer to [http://
|
|||
|
www.linux-usb.org] http://www.linux-usb.org for further details. The kernel
|
|||
|
documentation /usr/src/linux/Documentation/usb/usb.txt may also be helpful in
|
|||
|
determining which type of controller you have.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
3.4. Configure/Build Kernel
|
|||
|
|
|||
|
Now we need to configure, and make your kernel. During configuration, make
|
|||
|
sure you enable the following entries. You may either compile them directly
|
|||
|
into your kernel, or as modules. It is highly recommended that you compile
|
|||
|
them as modules. If you compile them directly in, you will need to reboot.
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>USB support (CONFIG_USB)
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>The preliminary USB Device Filesystem (CONFIG_USB_DEVICEFS)
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>The appropriate controller - UHCI, or OHCI (CONFIG_USB_UHCI, or
|
|||
|
CONFIG_USB_OHCI)
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>USB Serial Converter support (CONFIG_USB_SERIAL)
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>USB Handspring Visor Driver (CONFIG_USB_SERIAL_VISOR) (serial converter's
|
|||
|
sub-option)
|
|||
|
|
|||
|
|
|||
|
There are two UHCI drivers. You do not want the "UHCI Alternate (JE)" driver.
|
|||
|
This driver does not yet support all the USB features which the Visor uses.
|
|||
|
Thus, you will be unable to sync using this driver. If you are unable to see
|
|||
|
the original driver, ensure that the UHCI-JE driver is NOT selected, you
|
|||
|
should then see the option for both drivers.
|
|||
|
|
|||
|
Here, you should decide if you would like to include Hotplug support. With
|
|||
|
Hotplug support, you are able to auto-magically sync your visor by only
|
|||
|
pressing the Hotsync button. Please see the hotplug section, and especially
|
|||
|
the Hotplug Kernel Config, before choosing this route.
|
|||
|
|
|||
|
Compile and install as required. Don't forget to run lilo. If you are
|
|||
|
installing a new kernel image, do not reboot yet.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
3.5. usbdevfs
|
|||
|
|
|||
|
usbdevfs puts information about your USB bus into the /proc directory tree.
|
|||
|
Its a good thing, and can be especially useful for debugging. You can enable
|
|||
|
it by adding the following line into your /etc/fstab.
|
|||
|
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|none /proc/bus/usb usbdevfs defaults 0 0 |
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|
|||
|
If you installed a new kernel image, you could reboot from this point on.
|
|||
|
Remember, if you are just adding the USB info as modules, you do not need to
|
|||
|
reboot.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
3.6. Making /dev Entries
|
|||
|
|
|||
|
If your linux distro does not come with USB Visor support, or if you are NOT
|
|||
|
using devfs (not the same thing as usbdevfs), you will need to make the USB
|
|||
|
tty devices.
|
|||
|
|
|||
|
If you are using devfs, these devices are automagically created under /dev/
|
|||
|
usb/tts/{0,1,...}; so you can skip ahead to using the modules
|
|||
|
|
|||
|
If you are not using devfs, you can create the devices by executing these
|
|||
|
commands, as root:
|
|||
|
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
| mknod /dev/ttyUSB0 c 188 0 |
|
|||
|
| mknod /dev/ttyUSB1 c 188 1 |
|
|||
|
| mknod /dev/ttyUSB2 c 188 2 |
|
|||
|
| mknod /dev/ttyUSB3 c 188 3 |
|
|||
|
| etc... |
|
|||
|
| chmod 666 /dev/ttyUSB* |
|
|||
|
| |
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|
|||
|
You are able to have up to 255 connections/ports/devices, but unless you have
|
|||
|
more than one USB serial device, you'll probably only need the first few. The
|
|||
|
chmod is to allow users to be able to access the Visor device. It is the
|
|||
|
opinion of the author of this document that this should be safe for a
|
|||
|
personal computer. Multiuser computers may want to look into the security for
|
|||
|
this (please let me know).
|
|||
|
|
|||
|
When a Visor connects, there are two "ports" opened. (For most people, this
|
|||
|
will be /dev/ttyUSB0, and /dev/ttyUSB1). The first port (zero), is a generic
|
|||
|
connection. The second port is the hotsync port. This feature allows for
|
|||
|
future developments; for example, to export a filesystem from the Visor. A
|
|||
|
useful thing to do is to create a link to the hotsync port so that
|
|||
|
synchronization software will use the appropriate device be default. You can
|
|||
|
do this by:
|
|||
|
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
| cd /dev |
|
|||
|
| ln -s /dev/ttyUSB1 pilot |
|
|||
|
| ln -s /dev/ttyUSB1 palm |
|
|||
|
| |
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|
|||
|
The software package pilot-xfer uses /dev/pilot by default. coldsync defaults
|
|||
|
to /dev/palm. Create devices and links as appropriate. Just for fun, you
|
|||
|
might also want to create a link from /dev/visor to /dev/ttyUSB1, just, well,
|
|||
|
because we have a visor, not a pilot (or Palm(tm)). The actual device number
|
|||
|
may change, depending on how many (active?) USB-serial devices you have on
|
|||
|
your system. A message containing the device actually used is entered into
|
|||
|
syslog. Eventually, the idea is to make an entry in the /proc filesystem
|
|||
|
which contains the needed information.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
3.7. Using the Modules
|
|||
|
|
|||
|
For people who compiled the USB code as modules, you will also need to insert
|
|||
|
the modules into the running kernel. When you want to use the visor, you will
|
|||
|
need to runt the following commands as root:
|
|||
|
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
| /sbin/modprobe usb-uhci |
|
|||
|
| /sbin/modprobe usb-ohci |
|
|||
|
| /sbin/modprobe visor |
|
|||
|
| |
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|
|||
|
One important note is that the actually driver/device connection for /dev/
|
|||
|
ttyUSB* are not created in the kernel memory until the hotsync button is
|
|||
|
pressed. Therefore, if you try to use any software before pressing the
|
|||
|
hotsync button, it won't work.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
4. Synchronization Software
|
|||
|
|
|||
|
4.1. General
|
|||
|
|
|||
|
There are two software packages which communicate with your Visor. The first
|
|||
|
is coldsync, and the second is pilot-link. These programs are command-line
|
|||
|
based, and do "low-level" synchronization of the actual databases. They
|
|||
|
provide [different] interfaces for conduits. I assume you know how to
|
|||
|
download and install programs yourself. If not, learn. (I suppose you could
|
|||
|
cheat and install a pre-compiled package, but I don't support that ;-).
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
4.2. coldsync
|
|||
|
|
|||
|
coldsync can be found at [http://coldsync.org/] http://coldsync.org/.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
4.3. pilot-link
|
|||
|
|
|||
|
pilot-link can be found at [http://www.pilot-link.org/] http://
|
|||
|
www.pilot-link.org/. If you plan on using a Palm Desktop Equivalant, you'll
|
|||
|
want to use this package.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
4.4. Time to Sync
|
|||
|
|
|||
|
At this point we should be able to test to make sure things are working. Of
|
|||
|
course, the visor needs to be in the cradle, and the cradle needs to be
|
|||
|
plugged into your USB port. The proper modules should be loaded.
|
|||
|
|
|||
|
NOTE: you MUST press the hotsync button BEFORE running the software. The
|
|||
|
visor driver will make an entry in syslog, and, eventually (ie, in newer
|
|||
|
drivers), to /proc/drivers/visor. Assuming the driver connects to /dev/
|
|||
|
ttyUSB0 and /dev/ttyUSB1, you may run your program to backup the visor (chose
|
|||
|
the appropriate program):
|
|||
|
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|cd ~ |
|
|||
|
|mkdir visorbackup |
|
|||
|
|coldsync -p /dev/ttyUSB1 -mb visorbackup |
|
|||
|
|pilot-xfer -p /dev/ttyUSB1 -b visorbackup |
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|
|||
|
If you get an error such as "unable to bind to the port", you probably need
|
|||
|
to re-read the previous paragraph. With any other errors, please refer to the
|
|||
|
Troubleshooting Guide.
|
|||
|
-----------------------------------------------------------------------------

4.5. Palm Desktop Equivalents
|
|||
|
|
|||
|
There are a few Palm desktop equivalents. I haven't had time to test them. I
|
|||
|
intend, at some point, to put something about them in here. If you want to
|
|||
|
write up something to have it included here, please feel free to send it in.
|
|||
|
To my knowledge, all of them use the pilot-link libraries to talk with the
|
|||
|
Visor.
|
|||
|
|
|||
|
Here is the list that I know of:
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>[http://www.jpilot.org/] J-Pilot

4.6. Your Done!
|
|||
|
|
|||
|
At this point, you are done! You are able to install, backup, and syncronize
|
|||
|
your information. Congratulations! I would appreciate an email of gratitutde!
|
|||
|
The next sections talk about setting up a PPP connection and Hotplug support.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
5. Hotplug-able
|
|||
|
|
|||
|
You must be using a fairly recent v2.4 kernel for this. You may wish to read
|
|||
|
over the whole section before proceeding.
|
|||
|
|
|||
|
Hotplug will allow you to automatically run your syncronization software when
|
|||
|
you press your sync button. You will only be able to configure this to sync
|
|||
|
for one Visor. If you need to be able to sync multiple users with differen
|
|||
|
Visors, you can't. (With different Palm's and Clie's, is a separate question,
|
|||
|
to which I don't know the answer to).
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
5.1. Hotplug Kernel Config
|
|||
|
|
|||
|
You will need to enable "Support for hot-pluggable devices" under "General
|
|||
|
Options" in the kernel config. This is the kernel option CONFIG_HOTPLUG. Make
|
|||
|
sure you compile/re-install.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
5.2. Installing Hotplug
|
|||
|
|
|||
|
You need to get the hotplug scripts from the linux-hotplug homepage: [http://
|
|||
|
linux-hotplug.sourceforge.net] http://linux-hotplug.sourceforge.net. The
|
|||
|
scripts are available as a rpm package or tarball If installing the tarball
|
|||
|
package, please read the README file that is included on proper installation
|
|||
|
procedures. If all you are configuring is the Visor hotplug support, then
|
|||
|
most likely you'll just have to do this:
|
|||
|
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
| gzip -dc hotplug-2002_08_26.tar.gz | tar xvf - |
|
|||
|
| cp hotplug-2002_08_26/sbin/hotplug /sbin/hotplug |
|
|||
|
| cp -r hotplug-2002_08_26/etc/hotplug /etc |
|
|||
|
| |
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
5.3. Configure the Visor Driver
|
|||
|
|
|||
|
When all is said and done, an (executable) script named /etc/hotplug/usb/
|
|||
|
visor should get run when you press the hotsync button.
|
|||
|
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
| #!/bin/sh |
|
|||
|
| /bin/su rvbijl -c /usr/local/bin/coldsync |
|
|||
|
| |
|
|||
|
+---------------------------------------------------------------------------+
|
|||
|
|
|||
|
Obviously, you would want to replace the rvbijl39 with your normal user
|
|||
|
account. And make that script executable.
|
|||

6. Troubleshooting Tips
|
|||
|
|
|||
|
6.1. The Tips
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>There is a known bug about the Visor that sometimes you need to reset the
|
|||
|
Visor before it is able to sync properly. This is the number one solution
|
|||
|
for most people having problems syncing. If a soft reset does not work,
|
|||
|
and other USB devices work on this machine on Linux, a hard reset has
|
|||
|
been known to solve the problem. (Try some of the other suggestions
|
|||
|
before doing a hard reset).
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>Did you install the new kernel/modules?
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>Make sure that all the modules are running. The command is lsmod and
|
|||
|
there should be, at least, these modules: visor, usbserial, usbcore; and
|
|||
|
one of the following: usb-uhci or usb-ohci.
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>If you installed a new kernel, did you reboot?
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>Is the USB hardware enabled on your computer? (Check your BIOS. Does it
|
|||
|
work in other operating systems?)
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>Are things (ie "usb-serial") appearing in /proc/devices? In /proc/bus/usb
|
|||
|
/devices? If not, then the drivers aren't being loaded properly.
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>Is there any information being entered in syslog when you press the
|
|||
|
hotsync button?
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>Did you really remember to press the hotsync button BEFORE running your
|
|||
|
synchronization script?
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A>Email <usbvisor-unix@lists.sourceforge.net>.
