This is a modem made by Philips.  I'm not really sure if snd-usb-audio
should support this device ...  ;-)

Miditech's vendor ID is 0x4752.

Well then something fishy is going on, since the keyboard is reporting
that on both computers I have, and the windows driver has no problems.

Are you sure that this is the data of the keyboard?  Aren't there any
other devices in the lsusb output?

mstart-2.inf from the miditech.de driver package says:
%USB\VID_4752&PID_0011.DeviceDesc%=MIDUSB.Dev, USB\VID_4752&PID_0011

The usbserial driver didn't get used when I compiled it.

That file is identical. All the files in the driver package you can
download from the Miditech homepage is dated 2003-11-08. The sys and the
ini-file are dated same on the cd version, but the inf file, the cpl
file and the install executable are newer (2003-11-11). The sys files
are identical in both.
