mcleodnine,
sorry about taking so long getting back to your post. I don't know if I have 'usb_dc2xx' or not. When I try a modprobe it says no such command or something like that. So, I guess I don't know anything about modprobe

when I do a man on it, it lists it, but only in section 8. I decided to do some homework for you, though so bear with me. First, I did: #cat /proc/bus/usb/drivers and I get the following:
usbdevfs
hub
96-111: hiddev
hid
48- 63: usbscanner
I don't know if that helps or not. Second, I got the output from both dmesg, which gives me the following:

Sorry about the length. I cut off a lot of stuff at the top to shorten it a bit. Then I did a tail on /var/log/messages to get this:

It looks like it isn't finding any drivers for the camera. I hope this helps you some. Sorry about the length.
