XFPS problem

[Raja54]

I recently bought xfps 4.0 speed. It doesn’t work !! Whenever I connect it to
my xbox and to pc all works fine. I play well for 1 or 2 minutes, but soon
after the connection beween pc and console is lost: I need to unplug the usb
pc-cable from device, plug it again, press F11 to give control to the pc
then press F12 to re-enter in the game (the character, during this time,
continue to move all around the scene without any control). I tried to change
PC, operating system (I tried with Vista 32, Vista 64 e XP), mouse and
keyboard: it always the same !! I've read on this forum another gy had the same problem. Is there anyone else who can help me ???
