hello,I'm a windows programmer. I've recently met a problem on usb driver, sincerely hope I could get your reply.
My usb driver doesn't work well with usb device. It's a webcam device. when I start this webcam, it always display white no matter what we show before it. I use bus hound to analyse it's urb data. All shows normal except URB_ISOCH_TRANSFER. It seems the device lose a lot of packets. The platform is Windows XP. Is there any trick on iso transfer? by the way,Does StartFrame in URB_ISOCH_TRANSFER struct change every time when I sumbit urb? Is there any example?
