Having bought a Kinstone "PC Camera" that claims to be Linux-compatible, I am having problems getting it to work properly.
The instruction pamphlet claims that drivers are available at
www.lodall.com/drivers/c2/ but the link there is to a RAR archive that Ubuntu's package manager claims is unsupported.
Running up camorama, a colour image is shown, but the red and blue channels are swapped (so my blue shirt appears to be red, and my skin has a bluish hue). Acquiring an image in GIMP and swapping the channels over restores the correct colours.
How can I swap the red/blue colour channels back?
After unplugging and re-plugging the device a few times:

edit: I've just discovered the existence of the "colour correction" filter in Camorama, but that doesn't help with acquiring images through GIMP or other applications. Any ideas on how to fix this at the driver/v4l level would be much appreciated.
