I'm developing driver for EZUSB-based system. When I use continuous iso-transfer (several urbs connected in the ring), every 986 (sometimes +-3) I get 1 or more urbs, which complete in reverse order.
For example, start_frames in completion routine show up like 20, 21, 23, 22, 24. The next error would be like 6, 7, 9, 8, 10 ... Sometimes even 0, 1, 6, 5, 4, 3, 2, 7, 8 ... No missing data, just reverse order. This is with 2.4.20, UHCI (uhci.o) in Dell Inspiron. Is this a known phenomena, my misunderstanding of something or a bug ... By the way, is there a thumb rule, of how many urbs one should have in a ring ?
