Re: NetBSD driver

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...

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...

Hey folks -- I'm the author of the NetBSD driver. The device driver is now merged with the rest of the system: http://cvsweb.netbsd.org/cgi-bin/cvsweb.cgi/src/sys/dev/usb/pseye.c Here's some additional information that I've discovered, but not yet been able to do much useful with: SCCB reg 0x29: app...
