As a rule, often the stock kernel, or operating system, of your initial installation may already have support for what you need.

Because of the expiration of the Non-Disclosure-Agreement between Philips Corporation and the former maintainer of the <filename>pwc</filename> driver, support for Philips PWC-chip-based webcams has ended. The driver will no longer be offered in the kernel source and the binary-only part will no longer be maintained. For a discussion of the issues behind the decision and (as of this writing still available) source patches, see <ulink url="http://www.smcc.demon.nl/webcam/">http://www.smcc.demon.nl/webcam/</ulink>.
Because of the expiration of the Non-Disclosure-Agreement between Philips Corporation and the former maintainer of the <filename>pwc</filename> driver, the previous kernel support for Philips PWC-chip-based webcams has been removed. Luckily a new, still experimental driver that does not require a proprietary module is under development. The old site, with a discussion of the change, can be seen at <ulink url="http://www.smcc.demon.nl/webcam/">http://www.smcc.demon.nl/webcam/</ulink>; the new driver is maintained at <ulink url="http://www.saillard.org/linux/pwc/">saillard.org</ulink> with more information at the <ulink url="">PWC Documentation Project</ulink>.
