Hi.
My brother has a yamaha psr-e423 keyboard. I tried hooking it to my Fedora machine, and the kernel recognized it (used dmesg and lsusb to test). Then I tried using it with the rosegarden midi editor, but it didn't show up in rosegarden's midi device manager.

What am I doing wrong? Should I use another app? start some sort of crazy audio daemon? edit configuration files?
