Subject: [PATCH] usbmidi (0.9.0rc7) output endpoints detection for MIDIStreaming protocol
Date: Mon, 3 Feb 2003 00:56:26 +0100 [thread overview]
Message-ID: <200302030056.26089.plcl@telefonica.net> (raw)

Hi,
Attached is a patch to solve a little mistake with output endpoints detection
for standard USB MIDI devices. Midisport devices are affected only if using
Lars Doelle firmware.
Typical syslog output was like this:
kernel: snd-usb-midi: MIDIStreaming version 01.00
kernel: snd-usb-midi: EP 01: 2 jack(s)
kernel: snd-usb-midi: EP 81: 2 jack(s)
kernel: snd-usb-midi: created 0 output and 4 input ports
kernel: usb-uhci.c: ENXIO c0008480, flags 0, urb c1b665a0, burb c1b664a0
kernel: snd-usb-midi: usb_submit_urb: -6
Regards,
Pedro
