As an update, I think I understand why the rt2x00 version cannot recover
from the rfkill block. In addition to flushing the USBs tx queues, it also
flushes the rx queue, which calls usb_kill_urb. I have emulated that
function to simply wait for the packet to complete. For tx queues that's
fine, either the transmission goes through or it errors and eventually it
will clear. But rx urbs can sit indefinitely in the queue, and looking
through the Usb::Connection interface and Packet_stream_tx I don't know if
I can see a way to pull something out of the queue after it's been added.
If I understand it right, that would require re-doing things in a pretty
major way. But, on the bright side, if you don't use the rfkill feature
(and you can always physically remove a USB device anyway), it's useable
for me.
