USB to ps/2 converter problem

[Roar Pettersen]

Hi !


We have two Dell PowerEdge 2950 which only have USB mouse & keyboard,
therefore I'm using a USB to PS/2 converter to get the KVM switch to
work with the servers.

When I boot FreeBSD-6.2 kernel (from feb. 2007) then the system detects
the usb converter :

ukbd0: CHESEN PS2 to USB Converter, rev 1.10/0.10, addr 2, iclass 3/1
kbd2 at ukbd0
ums0: CHESEN PS2 to USB Converter, rev 1.10/0.10, addr 2, iclass 3/1
ums0: 5 buttons and Z dir.

If I build a new kernel with GENERIC kernel configuration, then the 
converter isn't detected and the keyboard doesn't work. :-(

Here is more information from "dmesg -a" :

And here is some info from "usbdevs -v" :

The usb to ps/2 converter is on the /dev/usb3 port 5.
