I tried RedHat 9.0 and the CCRMA stuff, but I guess I mustn't have setup
the modules.conf file properly. I'm used to the monolithic kernel
approach, and I found the whole modules.conf thing confusing. I assume I
need an entry in there to load the USB MIDI interface driver - could you
send me your modules.conf so I can see what sort of entries are
required?

I'll try this approach tonight.
Has anyone had succes in getting SysEx data
flowing back and forth
between Roland sound modules and their computer?
Yes, SC-8820, over USB.
I have attached my
simple test program in case I'm doing something obviously wrong.
I see nothing obviously wrong.
It might be time-saving to try the low-tech approach first:
do a "cat /dev/midi42 > somefile", then, on another console, run:
echo -ne '\xf0\x41\x10\x16\x11\x04\x01\x76\x00\x01\x76\x0e\xf7' > /dev/midi42

My unit's light is active while the dump is being transmitted (several
seconds, depending on the size of the data). Are you sure your's is
sending anything?
I have tried
using Linux, but gave up when I couldn't get ALSA or
OSS to recognise my USB MIDI interface, (a Yamaha UX96). Under
NetBSD it's recognised as soon as I plug it in.
Any somewhat recent version of ALSA does support the UX96.

The snd-usb-audio driver doesn't really need any entries in
modules.conf, except when you want to force it to have a specific card
number.
The module should be automatically loaded by the hotplug scripts when
you plug in the USB device (or when booting).

My knowledge is limited to GS sysexs only, but I think your address
04 01 76 / length 00 01 76 may not be correct. The lower two bytes are
identical. Does the parameter at address 04 01 76 really have a length
of F6h bytes?

The MIDI activity light flashes *very* briefly, so it could be that
nothing's being sent back.

Something like the following: (I'm assuming you have another sound
card as the first card)
# ALSA stuff
alias char-major-116 snd
options snd cards_limit=2
alias snd-card-0 snd-whatever
options snd-whatever index=0 some_option=42
alias snd-card-1 snd-usb-audio
options snd-usb-audio index=1
# OSS emulation stuff
alias char-major-14 soundcore
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-8 snd-seq-oss
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-12 snd-pcm-oss
alias sound-slot-1 snd-card-1
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss
