The mouse in question is a Microsoft IntelliMouse (optical). It is
detected and initialised, and works fine - for a while. After some
seemingly random time, and for no apparent reason, it goes missing. The
pretty red glow from underneath goes out. The pointer disappears from
the screen.

mine never stops the dull flashes, not even if PC is powered off for some

improve on accuracy I guess.

It does leave a bit of a trail in the syslog, but unfortunately it
doesn't mean a lot to me. Here is a sample:

Those are the "I'm not quite getting a handle on this thing" messages. I
saw that just recently when messing around with hooking up my new Palm
Pilot cradle to my laptop (too new to have Linux support yet.

a slightly different module got me past that step.

your device got disconnected and the usb-module tries to reconnect it with
a new number. But your mouse doen't like the number it seems.
</blockQuote>
<blockQuote>
The question is: why does it disconnect?
</blockQuote>
<blockQuote>
How about new batteries if it's cordless? check the plugs if with cord?
Does it beep when it fails the first time? Mine beeps on changes in the usb
devices.

After that X doesn't know the mouse any more. I guess the <TT>/dev/usb/mouseX</TT>
changes with the usb-device number and X will fail to read mouse0. I use it
on a laptop right now and the coreinputdevice is my touchpad, the mouse is
set to sendcoreevents in <TT>/etc/XF86Config-4.</TT>
This way X will not complain if the usb mouse is not there (but will not
accept it reconnected later).
</blockQuote>
<blockQuote>
Restarting X is usually sufficient to get it working, I'll check if the usb
device is changing the <TT>/dev/usb</TT>(mouseX number as well next time restarting.

This sounds a lot like something is intermittent. Is the mouse plugged
directly into your machine, or a subsidiary hub?
</blockQuote>
<blockQuote>
Any possiblity you have a second USB mouse you can borrow to test?

Rather than suggesting a specific driver, which is only a small part of the
picture, I'm going to send you to the place that got me as far as it was
possible to get in my chase; I would say that you should be able to resolve
your problem without too much trouble, since there's a whole section
dedicated to USB mice. Go to <A HREF="http://www.linux-usb.org"
>http://www.linux-usb.org</A>, and read the stuff
in order, starting at the top (you can skip the sections that don't apply,
but you do need to start at the very beginning or you'll miss important
things.)

Failing that, you actually may find it possible to make the USB subsystem
more stable by compiling the correct USB "hub" driver into your kernel.
</blockQuote>
<blockQuote>
In this case UHCI support.
</blockQuote>
<blockQuote>
I also note that one of the USB hub flavors, UHCI ... yes, that's right,
the one you are using ... has two different possible drivers to use for
basic hub support. <EM>I</EM> have never discovered any difference using either
one, but maybe your system wants "the other one" . You can try it as a
module first and see.
</blockQuote>
<blockQuote>
Anyways my dad-in-law has a usb keyboard that lets the mouse plug into its
back "piggyback" style - and we got better USB behavior by building usb-uhci
into the kernel. Very minor difference, but he lives in X, and mouses
being strange on you don't make a happy GUI.

That was actually what worked for me, but I wanted him to have the big
picture: understanding the USB process and tweaking the few small variables
seems to be the way to go. I got <EM>this</EM> close with the Palm Pilot, even
though it's not supported yet: got USB to recognize it as a valid device
(!), one that did not get dropped... I wish I knew more about writing
drivers and protocol parsers, but it's about #16,761 on the priority list.

Since it doesn't seem to be able to locate the mouse after it dies,
this may not be possible; I'm not a USB mechanic (yet); someone else
will probably have a better answer here.

restarting X seems not to suffice in your case since the mouse doesn't like
a new number asigned.

Well, you aren't inquring about Motorola SoftModems on Windows 2000, so
I'd say you're pretty much ok for now. Hell, you even included the
syslog segment. You go, boy.

Hi!
</blockQuote>
<blockQuote>
I can't contribute much, but maybe you can get it to work again
by removing the module (looks like a module to me) and inserting it
again. I'm not sure if some other module has to be removed and
inserted first. Try <TT>/sbin/lsmod</TT> to see if it is a module (and being
used) and then rmmod usb-uhci and modprobe usb-uhci. Give it a try,
maybe it works.
</blockQuote>
<blockQuote>
<IMG SRC="../../gx/dennis/bbub.gif" ALT="(!)"
HEIGHT="28" WIDTH="50" BORDER="0"
> [Ben]
Yep. Rebooting is unnecessary; you can just unload/reload the module - but
the problem is that the module that you're using is generating or missing a
ton of spurious interrupts, which eventually brings it to its knees.

So now I tried this again:
on disconnect the mouse (reciever) is dropped from valid input devices
(Xserver)
reconnecting the mouse will leave it unused.
</STRONG></P>
<P><STRONG>
restarting X will not find the mouse on <TT>/dev/usbmouse0</TT> as usually.
restarting with config entry pointing to <TT>/dev/usbmouse1</TT> does find the mouse
and it's working again.
</STRONG></P>
<P><STRONG>
Changing a link which is in the Config to point to the right device after a
disconnect/reconnect does <EM>not</EM> work.
Restarting X with the same link to ...mouse1 will work.
</STRONG></P>
<P><STRONG>
I guess you should fiure out why your mouse gets disconnected, everything
else is lots of trouble and strange things happening.
</STRONG></P>
<P><STRONG>
But basically restarting X with the right mouse device should suffice,
rebooting the whole system is not necessary here. But my mouse gets
reconnected without error, yours not.
</STRONG></P>
<P><STRONG>
That's as far as I can try help in this I think....
</STRONG></P>

X should stay working if you use <TT>/dev/mice</TT> (major 13, minor 63, type character)
but that doesn't make it less annoying that it's losing an entry.
</blockQuote>
<blockQuote>
However, nothing will help if your mousie's little USB plug doesn't like
staying in the socket. If you have a machine with more than one USB socket
try the other one and see if it clears up suddenly. In which case you'll
either need to give up on the flimsy socket, or use it only for devices
that aren't so darn picky.
</blockQuote>

Good luck.
