My usb midi keyboard (Edirol PC-50) doesn't show up in qjackctl's
connections window. It appears in the logs so I guess it's not
a hardware problem. (It also used to work fine with a previous
version of the distro I'm using now (Open Suse) and various
Fedoras.)
Any help appreciated,
Andras

jackd is started like this:

(I threw in that -X seq just as a shot in the dark. Things used to
work fine before without it.)
