[linux-audio-user] DR-880 problems with USB MIDI

Hello!

I recently bought a BOSS DR-880 drum machine and am
having problems getting it to be recognized
as a USB MIDI device on my Slackware 10.1

I use a 2.6.10 kernel with Alsa support compiled in.
I also have the snd-usb-audio module which works
perfectly with my XP MIDI Mate USB MIDI cable.

It gets recognized instantly when plugged in
and I see it as a MIDI device in qjackctl.

When I plug in the DR-880 via USB to my laptop
I see this in /var/log/messages:

Jan 19 23:56:01 localhost kernel: usb 3-2: new full speed USB device
using uhci_hcd and address 3

When I do "cat /proc/bus/usb/devices" I see:

T: Bus=03 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 3 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=ff(vend.) Sub=ff Prot=ff MxPS= 8 #Cfgs= 1

E: Ad=01(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=82(I) Atr=03(Int.) MxPS= 64 Ivl=1ms

However, dmesg says:

usb 3-2: new full speed USB device using uhci_hcd and address 3
midi: probe of 3-2:1.0 failed with error -5

What is error -5? I tried googling and searching the newsgroups
and searching this list for any help. No luck. I tried searching
for earlier BOSS models, the DR-770 and 670, nothing.

This link:
http://www.qbik.ch/usb/devices/showdev.php?id=3168

says that the DR-880 is supported from Alsa version 1.0.9 or later. I
use 1.0.10.

I do not know how to roubleshoot this problem. Why doesn't
the driver for the DR-880 load. I set up USB mode on
the DR-880 to MIDI, so no fuck-up there.

Could you please offer some assistance, I would like
to sync the DR-880 with the Muse sequencer so
it starts playback when I press Play in Muse and
I want it to playback from a ceratin point when
I adjust the playback slider in Muse.

Once again, I kindly ask for help.

Best,

Hiram.
