okay I got some USB Devices (Joysticks to be more percice) and what I
want to do is  be able to play some games in my living room. my
desktop computer however is a few rooms away.  now I managed to pipe
in the output from the video & sound Cards to the living room tv,  and
I got a laptop connected wirelessly to my desktop comptuer. Bouth
Compys are running XP (home) and I was wondering if there was some way
I could set things up so that usb devices on the laptop can be treated
as if they where on my desktop. I don't mind if I have to buy extra
stuff to do this and then can't access the device on the laptop wile
it's beeing "ported."  I just need to know if it's posible and if so
what I need to get to do this.

i dont think this is possible but will keep looking

I got the Idea from reading the site www.usb.org  it seems to imply on
the site that it's posible but doesn't mention how.

It is possible and you will need to create a Virtual Remote Port

This can be done in several ways but I am not authorised to respond as
an Answerer hence it would take too long to commment on.

Try and this link and work from there
