We tried that with Juan (and many other things :-) We loaded the firmware
into Juan's 1x1 in two different ways, with the ezusb2131 software and
then with fxload and a script that is triggered by hotplugging. Both
attempts end up in the same way, the firmware loads fine, the device
disconnects but it never reconects again (loading the usb-midi module,
either oss or alsa, does nothing). All three LEDs in the interface stay on
and none of them blink (as the documentation says).

I just took a look at the Midiman web site and the interface Juan has does
_not_ look like the one in the 1x1 manual, it does not have MIDI
connectors in it, just cables that end in female MIDI connectors, and it
looks smaller.

My guess is that this particular Midiman 1x1 interface uses slightly
different hardware and is not compatible with the custom firmware...

We also tried with a Quattro, but the built in interface was not
recognized either (but we did not try as hard :-)
