usb: do not reset if a low-speed or full-speed device timed out
commitpull/10/head6e01827ed9
upstream. Some low-speed and full-speed devices (for example, bluetooth) do not have time to initialize. For them, ETIMEDOUT is a valid error. We need to give them another try. Otherwise, they will never be initialized correctly and in dmesg will be messages "Bluetooth: hci0 command 0x1002 tx timeout" or similars. Fixes:264904ccc3
