Identifying chipset/driver - spca or not?

[Anne]

Recently I bought a PCLine PCL-100K webcam.  PCLine is a store-chain own
brand, so it's probably a re-badged device.  I bought this because it is
listed as 'working', but when I got it home I didn't know how to find out
what driver was required.  Some kind soul told me that it needed the gspcav1
driver, and I installed the atrpms build of it.

The driver has been working, but with some colour issues.  Last evening I was
told about the CVS mailing list.  Searching the archives I came across mention
of the command spcacat, which gave the following information:

How can I find what driver I should be using?

It sounds as though it is amazing that it is working at all with the gspcav1
driver.

Hi,
glad you used the right forum for this type of question
I wouldn't know much on how to help, best way is to search for your webcam's model number + "linux" in google, it might help.
You could also type 'dmesg' right after you plug the camera and see the last few lines (or grep through dmesg output for 'video') to see if it tells you "XXX driver loaded" or something...
if you can make it work, then it's alerady a good thing !
