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. [ The bug has been present from the very beginning in the staging driver time, but Fixes below points to the commit moving to sound/ directory so that the fix can be cleanly applied -- tiwai ] Fixes: 61864d844c29 ("ALSA: move line6 usb driver into sound/usb") Signed-off-by: Fabián Inostroza Cc: Signed-off-by: Takashi Iwai --- sound/usb/line6/midi.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'sound/usb/line6/midi.c') diff --git a/sound/usb/line6/midi.c b/sound/usb/line6/midi.c index 6d7cde56a355..e2cf55c53ea8 100644 --- a/sound/usb/line6/midi.c +++ b/sound/usb/line6/midi.c @@ -125,7 +125,7 @@ static int send_midi_async(struct usb_line6 *line6, unsigned char *data, } usb_fill_int_urb(urb, line6->usbdev, - usb_sndbulkpipe(line6->usbdev, + usb_sndintpipe(line6->usbdev, line6->properties->ep_ctrl_w), transfer_buffer, length, midi_sent, line6, line6->interval); -- cgit v1.2.3
