FreeBSD V5.0 and USB to Serial on Toshiba Satellite 1110

My Notebook (Toshiba Satellite 1110) does not have 
serial ports, so I wanted to connect a serial adapter.

The adapter is recognized (see below), but I can't access 
any of the serial ports:

root_at_sat# minicom
minicom: cannot open /dev/ucom0: Device not configured
root_at_sat#


root_at_sat# cu -l ucom0
/dev/ucom0: Device not configured
link down
root_at_sat# cu -l ucom1
/dev/ucom1: Device not configured
link down
root_at_sat#


I will be happy about any hint!
(the USB-mouse is working flawless!)
