This works, provided that the MidiSport is always at the
same USB bus address; in your case, you will have to
change the /004/003 to /002/003.
Hope that helps.
I'm interested by your comment "hotplug makes some real

getting the audio side of my Novation Speedio (a USB audio
and MIDI interface) to work properly (as per previous posts
on this list) - could this be related? If so, what do I do
to run it without hotplug?
Just one more comment while I'm mailing the list: if anyone
uses the Proteus 2000 (a hardware synth), you might be
interested in having a copy of a spreadsheet I've prepared,
which has descriptions of all the drums and percussion
sounds in the ROM it ships with. Let me know.

Thanks for the help! That looks very good.
#! /bin/bash
modprobe snd-usb-audio
cd /usr/share/usb/midisport
fxload -D /proc/bus/usb/004/003 MidiSportLoader.ihx -I \
MidiSport2x2.ihx
exit
Where do I get the files located in /usr/share/usb/midisport? There's
nothing like that on my system.

I don't know the Novation device, but I had some problems with the Maya
44 USB and some Tascam USxxx (both USB) together with hotplug. The
solution to both problems was to add the corresponding kernel modules to
the blacklist of hotplug. On Gentoo with the standard layout you find
the blacklist in /etc/hotplug/blacklist. On default there should be some
entries in it like 'usbcore' and 'usb-uhci'.

Well, it's kind of a catch22. The problem is that the USB device
numbers don't seem to be constant. My MIDI interface gets a
different address almost every time I plug it in.
There's no easy way to figure out where it got added, and if you have
multiple devices of the same make/model, you're actually SOL. hotplug
events gets sent when the device is plugged - so when hotplug gets
called is the only point in time when you can know what numbers your
device came up with.
So to be be 100% sure, you must use hotplug. If you're Speedio is the
only device you have, then it's pretty easy to just load the modules
by hand like you might for a PCI card - whatever USB numbers are
actually related to a device must be your box since you've only got
one.
FWIW - I don't think it'll help your audio issue. If hotplugging
brings up the MIDI side, loading modules by hand is going to do the
same thing. If you need some firmware, it could be an issue with the
firmware that you're loading.

New subject: [linux-audio-user] Re: M-Audio MidiSport 2x2 [SOLVED]
Thanks! I've got the missing files by eMail - and it works! For
documentation a short summary:
1) blacklist snd-usb-audio for hotplug
2) get the firmware of the device from the usbmidi project (or from
somewhere else)
3) get fxload
4) use the following shell script to load the firmware
#! /bin/bash
modprobe snd-usb-audio #if not already loaded at startup
cd /usr/share/usb/midisport
fxload -D /proc/bus/usb/*BUS*/*DEVICE* MidiSportLoader.ihx -I
MidiSport2x2.ihx
exit
Substitute *BUS* and *DEVICE* with the numbers you get by running lsusb.
Thanks to everyone who helped me!

Um, hold on, you should not have to blacklist snd-usb-audio to make this
work. Hotplug should load the firmware automatically.

yeah, that works fine here,
but all USB devices are "dead" after putting the system to sleep and waking it
back up, and have to be physically unplugged and replugged to work again (even
mouse/keyboard). whats the proper fix for this...coldplug? had the same problem on a
non-notebook when rebooting, the midisport has hte firmware already (pulsing LED...) but
still needed a re-plug to show up..

Yes, and it was doing so very well for my midisport device also.
I think there's some confusion in this thread. Some of us are having a
hard time when upgrading to versions of udev that supersede hotplug
(i.e. there is no hotplug). I have solved that problem but it wasn't
easy. I offer to help anyone with the same hurdle, and to help fix the
usb-midi-fw.sf.net project too (see the existing bug report [1]).
Others seem to be having unrelated problems on hotplug systems and are
opting for the simpler shell script solution. When you get tired of
running the shell script by hand, come back and we'll help you get it
working with (udev|hotplug). But if you're happy with the ad-hoc
solution, and would rather just get on with making music, well I can't
argue with that. :)
