usb_submit_urb() returns -ENODEV when a usb device is disconnected. In commit 4935f1c164ac528dff3538f97953b385ba500710 ("Bluetooth: btusb: be quiet on device disconnect") I stopped treating that return as an error in the three btusb_*_complete() functions.
It turns out btusb_send_frame() generates a similar error if the system is suspended while the bluetooth usb device is enabled. The sensible thing to do here seems to be to treat -ENODEV (and -EPERM) just like the btusb_*_complete() functions now do.
