From: Pavel Rojtberg <[email protected]> this code was probably wrong ever since and is redundant with xpad_send_led_command.
Both try to send a similar command to the xbox360 controller. However xpad_send_led_command correctly uses the pad_nr instead of bInterfaceNumber to select the led and re-uses the irq_out URB instead of creating a new one. Note that this change only affects the two supported wireless controllers. Tested using the xbox360 wireless controller (PC).
