If you (and others here) really want to improve anything for rt2800usb, change your development system and use a raspberry pi (PI). Why PI? Because the PI doesn't cover any broken code / concept / driver architecture with hardware resources. You want to have an example? This device[1] achieves 140 MBit/s (data receiving) on the PI, measured with netperf and rt5572sta compared to rt2800usb, which achieves very very very poor 30 MBit/s(! - even w/ best radio conditions can't be achieved any more) but an extremely high CPU load at the same time! If you compare the basic behaviour of rt5572sta and rt2800usb, you will see, that rt5572sta uses a completely different usb handling, which doesn't need that much CPU resources as the one used by rt2800usb. Therefore: If you really want to improve rt2800usb, at first take a serious look at how usb is handled by rt5572sta and how to save CPU resources. In a nutshell: Use a few, but big USB packets instead of a lot of small ones, which needs a lot of interrupts / s and therefore needs a lot of CPU resources - which aren't available on the PI at all.
