My cable (see above in this thread), that works with my RC softwares and with FMS simulator, even on Win 2K and XP, has no problems on laptops, as it is powered by the RC transmitter (there are only 2 wires to the PC: data and ground).
If you do not have a COM port, use a serial to USB converter, it works fine.
