    Hi,

    Could you try some of the following tests to control the registers:
    I have grouped each test together, please don't do them all in one single shot,
    since that will not help narrowing down the exact register which breaks everything.

    > > 11 :0x0005 | 11 :0x000a MAC_CSR11: SIFS.
    > > 12 :0x016c | 12 :0x013a MAC_CSR12: EIFS.

    echo 11 > /<debugfsroot>/<mac80211>/rt2500usb/register/csr_offset
    echo 5 > /<debugfsroot>/<mac80211>/rt2500usb/register/csr_value
    echo 12 > /<debugfsroot>/<mac80211>/rt2500usb/register/csr_offset
    echo 364 > /<debugfsroot>/<mac80211>/rt2500usb/register/csr_value

    > > 33 :0xb11a | 33 :0xb162 TXRX_CSR1: TX configuration.

    echo 33 > /<debugfsroot>/<mac80211>/rt2500usb/register/csr_offset
    echo 45338 > /<debugfsroot>/<mac80211>/rt2500usb/register/csr_value

    echo 42 > /<debugfsroot>/<mac80211>/rt2500usb/register/csr_offset
    echo 14 > /<debugfsroot>/<mac80211>/rt2500usb/register/csr_value

    echo 2 > /<debugfsroot>/<mac80211>/rt2500usb/register/bbp_offset
    echo 30 > /<debugfsroot>/<mac80211>/rt2500usb/register/bbp_value
