This bug also caused problems with other usb devices.
What sort of problems? > After the device was removed from the system, the usb keyboard stopped > working until a hard reboot was performed (unfortunately I have no > kern.log of that event). I'm not familiar with the USB subsystem but I suspect that the rt73 driver may be holding a lock on the bus when it crashes, so no other drivers will be able to use their devices on that bus. > Below is the kernel log for booting with the device in the usb port.

Could you also send the output of "lsusb -v" with the device plugged in?
