PS2 Keyboard with USB adapter doesn't work

[pmatos]

Hi all,

I have a laptop, an external mouse and an external keyboard. Both external keyboard and mouse are PS2, so I bought a PS2->USB converter since the laptop has only 1 PS2 port.
Problem is that Gentoo is not recognizing the keyboard or mouse with converter. If I connect them to the PS2 port everything is ok but the other one which I try to use with the converter is not recognized by Gentoo and doesn't work. Not even if I do lsusb.

My intuition is that pure USB devices register themselves when they get connected but this is not happening with the mouse or keyboard since they are PS2 by default so I guess that configuration is more complex.
Any ideas on putting this to work?

EDIT: I just noticed this in the message log:

Have you tried it in Windows? Have you checked your bios?

Where I work it is hit and miss on what PS/2 keyboards will work with the adaptors. It is almost like the keyboard itself has to support being adapted to USB.
