After unplugging and replugging my Logitech MX700 mouse and then shutting
down my Linksys WPC11, I get the following badness message:

input: USB HID v1.10 Mouse [Logitech USB Receiver] on usb-0000:00:1d.0-1.4
orinoco_lock() called with hw_unavailable (dev=df2e8184)

I am using the 0.14alpha2 orinoco drivers on top of 2.6.0-test9-mm2. Previous
unloads of this driver did not produce this badness message until after I
replugged my mouse.

TIA
