Subject: [linux-audio-user] More Midisport 2x2 troubles

Hi all,
I just upgraded to Mdk 9.1 and reinstalled all of the MIDI-related
stuff, as well as the Alsa 0.9.2 (from sources, after uninstalling Mdk's
RPM's). I also installed Fernando's modified alsasound script that
enables smart unloading of snd- modules.
The end result is that the midisport works, well sort of.
The firmware loads fine, and the midisport is properly recognized. The
problem is that I only have one MIDI port available even though this is
the 2x2 version (I had 2 ports in Mdk 9.0, usually /dev/midi(0) and
/dev/midi1). Now I only have /dev/midi.
The interesting thing is that the /proc/asound/card1/midi0 lists the
following:
Output 0
Tx bytes : 0
Output 1
Tx bytes : 0
Input 0
Rx bytes : 5 (this number changes, most likely because
it's the only port that has anything hooked up to it)
Input 1
Rx bytes : 0
So, it seems that there are 2 I and 2 O ports, but they are all
allocated within the midi0 device according to the proc stuff (or
/dev/midi1 according to the dev stuff). If this is the case, then how do
I access the second port.
Cat /dev/midi1 only outputs stuff coming into the first port, so that
tells me something's fishy.
I am using CCRMA's hotplug 8_26_1 and ezusbmidi 2002_11_17.
There were no alterations to the kernel or any other part of the system
(apart from the alsa install and other audio software installs).
My modules.conf looks like this:
# ALSA portion
alias char-major-116 snd
alias char-major-14 soundcore
alias snd-card-0 snd-intel8x0
alias sound-slot-0 snd-card-0
alias snd-card-1 snd-hdsp

#alias sound-service-0-1 snd-seq-oss

#alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
#HDSP
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-1 snd-seq-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-8 snd-seq-oss
alias sound-service-1-12 snd-pcm-oss
#MIDISPORT
alias sound-service-2-1 snd-seq-oss
alias sound-service-2-8 snd-seq-oss
In this situation the hdsp is not in use, so midisport assumes the 2nd
card position.
Upon midisport reconnect, the /var/log/messages spits out the following:

(NB: what's up with the sound-service-2-2, is there such a thing?)
Upon doing this, cat /dev/midi1 is the only one that works.
Other pertinent info is (in abbreviated form):
/proc/asound/version -> ALSA=0.92 kernel=2.4.21-0.13mdk
../cards -> 0 i810, 1 2x2 (Midisport) at usb-00:1d.2-1
../card1/ has id and midi0 files only
All I also remember the last time when I was using 0.9.0 is that I had
to upgrade from CVS in order to get both ports (it was the snd-usb-audio
bug IIRC). But now, I did d/l and install 0.9.2 which should have those
fixes but I can't seem to get the second port to work. Could it be that
there's something leftover from the mdk 0.9.0 version of Alsa even after
I did rpm -e and reinstalled 0.9.2 from sources?
Any help on this issue is greatly appreciated! Sincerely,
