Trying to interface a C51 device to a PC PS2 port. I can't find information on the PS2 data packet. Of course I have searched MS web site but HDI driver information appears to locked up in the DDK sbscription kits. I googled a number of driver web sites that will sell drivers but I don't want to install a driver on Windows. I want to use the existing 'standard' Win drivers such as a common mouse driver. If anyone can point me in the right direction, it would be greatly appreciated. Brad
