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?

Has anyone had succes in getting SysEx data

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.
