From 7ecb46e9ee9af18e304eb9e7d6804c59a408e846 Mon Sep 17 00:00:00 2001 From: Fabián Inostroza Date: Thu, 12 Apr 2018 00:37:35 -0300 Subject: ALSA: line6: Use correct endpoint type for midi output MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Sending MIDI messages to a PODxt through the USB connection shows "usb_submit_urb failed" in dmesg and the message is not received by the POD. The error is caused because in the funcion send_midi_async() in midi.c there is a call to usb_sndbulkpipe() for endpoint 3 OUT, but the PODxt USB descriptor shows that this endpoint it's an interrupt endpoint. Patch tested with PODxt only.
