 * usb_queue_reset_device - Reset a USB device from an atomic context
 * @iface: USB interface belonging to the device to reset
 *
 * This function can be used to reset a USB device from an atomic
 * context, where usb_reset_device() won't work (as it blocks).

Please use it if you can. Your version for example is buggy.
It will oops if you unplug the device while a reset is scheduled.

Thanks for your suggestion. I would replace it.
