Notice that I applied the patch to version 207 (that's what it said on the
patch that you sent me). It "kind of works" in 206.

Yes, the Foxlink I can provide immediatly, but the Phillips will have to wait
for Sunday.

(continue many more of these Dropping payload, and then keep repeating the
Frame complete and EOF in empty payload)
But luvcview actually works after an initial 3-4 second delay. In these 3 or 4
seconds the following appears:
uvcvideo: Trying format 0x56595559 (YUYV): 1280x960.
uvcvideo: Using default frame interval 111111.1 us (9.0 fps).
uvcvideo: Setting frame interval to 1/15 (666666).

uvcvideo: Frame complete (EOF found).
uvcvideo: EOF in empty payload.
1280x1024: Same thing as the 1280x960 case. Here's the output of dmesg
uvcvideo: Trying format 0x56595559 (YUYV): 1280x1024.
