The driver detects the event correctly, then submits a URB to query the RC code. On the Extigy, the URB is submitted with a length of 2 bytes. My hardware, however, only replies with 1 byte, containing the correct RC button code. The current implementation discards this as being too short. (line 1784 of usbmixer.c) This patch specifies a "minimum packet length" in the remote control configuration. I've left the values for the Audigy 2/Live! the same as the packet length, as I'm assuming the existing code works with them. (I don't have the hardware to confirm) This fixes the Extigy RC support, e.g. for use with Lirc.
