My Windows 7 64 bit install is all good except for the Synaptics touchpad integrated into my keyboard. It is recognized as a Microsoft Serial Mouse, but the latest Synaptics drivers don't seem to 'do' serial. I have tried the new 14.0 driver, as well as an older 9.0 version designed for 64 bit Vista, but to no avail.
I've also tried a serial to PS/2 to USB conversion, and though the touchpad is then recognized as an HID compliant mouse, I can't get it recognized as a touchpad with scrolling, etc. I can't use it as a PS/2 mouse because my new motherboard only has a PS/2 keyboard connector.
I can't go back to the original keyboard manufacturer because they're long since out of business. Any help would be much appreciated.
