USBVideoClass Isochronous | Cypress Semiconductor
I've bin having some trouble getting these examples to work, once programmed the device disappears and reappear a couple of times. when lucky the video viewer shows one roll of the cypress mug and then looses connection to the device. most of the time it looses connection before any data transfers.
When I look at the USB log (taken with USBTrace, so not complete) it seems that it always fails once a BULK_OR_INTERRUPT_TRANSFER request is cancelled. I've attached the log file.
Also the endpoint listed with these BULK_OR_INTERRUPT_TRANSFER requests changes when I change the control interrupt endpoints servicing interval.
The only change I've made to the program is the VID so it loades generic uvc drivers.
If anyone got this example to work could you tell me how?
all this is done on a windows 7 x64 with the DVK board.
Thanks in advance,
