Part 1 of these fixes (http://www.spinics.net/lists/linux-usb/msg69842.html) resolves few issues around isoc transfer. It was able to handle specially those cases where application (gadget) was blocking, I mean during each giveback, gadget was taking too much time (more than 125 us) to call next ep_queue. Still I see some corner cases, which was failing. when gadget is non blocking, ie it does not call ep_queue during giveback, if it does not have any data. Now another thread will call ep_queue, whenever data is available. These patch sets resolved this issue. I am sending these patches as RFC only. May be can be added after few more tests.
