Hmmm... I tried motion and fswebcam, and they cannot seem to communicate with it. Motion complains about an unsupported pallette (GBRG), and fswebcam says it times out waiting for frames. The same thing happens if I try this LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so trick I have seen online.
I wasn't able to talk to it on my laptop either.
Both are Arch linux though, i.e. similar kernels and drivers installed I suppose, so perhaps I should see what happens on another machine, e.g. Gutenberg.
Do you happen to know what driver you were using?
Some info on my end:
Bus 002 Device 011: ID 0461:0815 Primax Electronics, Ltd Micro Innovations IC200 Webcam
Driver Info (not using libv4l2):
Driver name : spca561
Card type : iCam320
Bus info : usb-musb-hdrc.1.auto-1.3
Driver version: 3.12.0
Capabilities : 0x85000001
Device Caps : 0x05000001
journalctl -b -k

...that "device v0461 p0815 is not supported" is not very promising... I wonder if that is the spca561 driver saying that...
