Thank you.

Your device exposes five formats: YUY2 (YUYV), YV12 (YVU420), NV12, P010 and 
BGR3 (BGR24). They are all supported by V4L2 and the uvcvideo driver except 
for the P010 format. This would be easy to fix in the uvcvideo driver if it 
wasn't for the fact that the P010 format isn't support by V4L2. Adding support 
for it isn't difficult, but I don't have time to do this myself at the moment. 
Would you consider volunteering if I guide you ? :-)
