[LAD] Trouble setting h/w MIDI device as output port

I've been stumped for a while as to why my Tascam US-122 box stopped
working as a writeable midi port.

Using Debian Wheezy, everything was working up to a few weeks ago. MIDI
input still works and there's nothing suspicious in the /var/logs.

But...

nick@email-addr-hidden:~$ aplaymidi -l
 Port Client name Port name
 14:0 Midi Through Midi Through Port-0
 20:0 TASCAM US-X2Y TASCAM US-X2Y MIDI 1
 24:0 USB MIDI keyboard USB MIDI keyboard MIDI 1
nick@email-addr-hidden:~$ aplaymidi -p 20:0 Desktop/076903b_.mid
Cannot connect to port 20:0 - Input/output error
nick@email-addr-hidden:~$ uname -a
Linux arial 3.2.0-4-686-pae #1 SMP Debian 3.2.32-1 i686 GNU/Linux

Using older kernels doesn't help. Connecting e.g. rosegarden to the
TASCAM US-122 in qjackctl fails silently (the link is not made in the
connections window and nothing is printed on the console). Can't see
any module loading issues.

Is anybody else seeing this behaviour? I'd submit a bug report but
really can't figure out exactly what isn't working :(
