I in the test app I have #define LIBUSB_BULK_SIZE 16384 Interesting -- I'm actually doing much larger bulk xfers (full frame sizes) in my driver. Wasn't aware that I could get away with smaller. How do you detect end of frame? BTW that 7720Rev2.set is quite useful as a reference, I found (trivial i...

If you skip odd rows do you get an image as well? How big are your bulk xfers?

I believe Ekiga's handling of the camera is a result of something broken in Ekiga. The version of Ekiga I have installed wants to treat the YUYV progressive output as something else entirely. I also validated that Ekiga does tend to try to crop the camera when the output frame size is not settable ...

One thing I'd like to figure out is how to handle short bulk xfers. There appear to be 16-byte control packets in the stream when bandwidth is limited followed by a partial frame. There appear to be two cases where short reads happen: * 16-byte control packets: I have no idea how to decode these yet...

Here's a link to the .set file I was talking about: http://www.invisible.ca/~jmcneill/outgoing/7720Rev2.set If you look at the CameraSetting lines you get a bunch of magic registers, in the format: reg, value, mask. So I take something like: HKR,%7720Combo640X480%, Tag, 0x10001, 0x64048024 HKR,%7720...
