I use Ubuntu 10.04LTS from the beginning, and throughout that time the only thing that could not succeed was that this webcam is recognized but not working:
Bus 005 Device 002: ID 0c45:60fc Microdia PC Camera with Mic (SN9C105)
I use Ubuntu 10.04LTS 32bits and the kernel is 2.6.32-32-generic-pae. As I've been reading recently, which could for the kernel, a new search and I did not find any documentation that satisfactory.
In http://mxhaard.free.fr/spca5xx.html - appears as the webcam support Test and driver: spca5xx/LE - just bought this webcam to work on Linux, taking the version 9.04 on all other it worked, but now 10.04LTS repeats in the case of Ubuntu 9.04.
