Thats a critical issue, it is strange that only rt2800usb shows this
behavior and not rt2800pci.

Well this is a lower priority issue, if the driver works good for fixed rates,
the dynamic rates can be resolved later.

Nice.

No need. It isn't done in rt2500usb and rt73usb either. Readint the TX_STA_FIFO
register won't help either since it won't be filled in (it is only valid for rt2800pci).
