[linux-usb-devel] usb device driver- read -webcam

[rahul shetty]

We are writing a usb device driver for a webcam(twinkle). We are encountering a host of problems in writing the read entry point. We have opted for isochronous transfer but are now not in a position to proceed with it. We would appretiate any help which will guide us through as to "How does one perform isochronous transfer?".
Our code utilizes the URB structure for isochronous transfer. But once the URB is submitted it gives us a pending message and does not proceed from thereon.
Thank you.
