Hence there is a helper: * 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.
