Are there any drivers in the kernel that set urb->start_frame on every URB?
Could those drivers handle it if only the first URB they submitted to the host controller was scheduled for that frame ID, and all the rest of the URBs were scheduled ASAP?
BTW, urb->start_frame generally is ignored as an input parameter. Many host controller drivers pay no attention to it. Unless someone has a real reason, I think we are better off not using it.
