Thomann Andreas posted a mail to the list on September 15th 2006 and seemed to imply he would start a UVC gadget driver. You should try to contact him. > Another question, an UVC driver should open its sof interrupt, is it true? > Because if it doesn't, it won't be able to handle isoc packets on time and > could possiblly lose packets. > I am asking this because I am on a very low cpu clock environment, my > system can't handle sof interrupt that fast.

UVC devices must report the SOF counter value, but I don't think they need to process SOF interrupts if the device has a hardware SOF counter.
