Description of problem: USB transfers can process data in their callbacks sometimes causing unacceptable latency for other USB transfers. Separate BULK completion callbacks from CONTROL, INTERRUPT and ISOCHRONOUS callbacks, and give BULK completion callbacks lesser execution priority than the others. This way USB audio won't be interfered by heavy USB ethernet usage for example. Further serve USB transfer completion in a round robin fashion, instead of only serving the most CPU hungry. This has been done by adding a third flag to USB transfer queue structure which keeps track of looping callbacks. The "command" callback function then decides what to do when looping.
