Could be Arch already supports your webcam without you having to install any additional drivers. Have you tried simply plugging in your webcam and running a program like Cheese?

Re: webcam driver (trust) how to ?

I have a Trust branded webcam that used to work simply by plugging it in, but since the upgrade to kernel 2.6.39.1 it has stopped working. Here's what appears in dmesg when I plug it in:

I guess OP has the same problem. Any ideas on how to fix this?

I'd to report this bug to the kernel developers, but I'm not sure how. Could someone with more experience tell me a) what else I should include in the bug report apart from the dmesg output and kernel version and b) whether LKML is the right place for such a bug report?
