> a) How many interfaces and what kind of pipe is used?
Its only 1 interface on the camera. So that piece is done. It uses
Isochronous transfers.
16 alternate settings exist that varies the bandwidth from 0.5 MBit/s to 8
MBit/s. And of course one setting for 0 MBit.
> b) What video format is used? Number of different image sizes?
320x240 JPEG is what I have now. But the chip seems to support YUV4:2:2
Packed/Planar and YUV4:2:0 Packed/Planar. Packed format is JPEG compressed.
Image sizes that the camera seems to support is sub-QCIF (128x96), QCIF
(176x144), CIF (128x96), SIF (352x240), 320x240 and VGA (640x480). In VGA it
is only capable of 15 frames/s in the other formats it supports around 30
frames/s.
> c) Is decoder ready? What is the output format?
My code fetches JPEG compressed image data from the camera. At least i think
it is. The registers on the Winbond chip is enabled for JPEG data. I have not
written any code to verify it yet.

Lets hope so :-)
