I have a ps/2 connected ergonomic keyboard (part number 59758 ) branded as\nMicrosoft "Natural Keyboard." It connects and lights up, but the computer\nshows no response to the keyboard. (It works fine with my old 98SE computer.)\nSomewhere along the maze of trying to figure it out, there was a Vista\nmessage that there was a logitech ps/2 keyboard driver that may be missing or\ncorrupted (39). I can find no help on the microsoft.com site. A friend's\nUSB keyboard works fine, but I want my ergonomic keyboard back. A few\nother postings show vaguely similar problems with ps/2 keyboards.\nI tried unistalling keyboard drivers, but the only one showing with the\ndevice manager was the USB keyboard. It uninstalled. I rebooted with the\nUSB unplugged and the PS/2 plugged in. The PS/2 keyboard was still\ninoperative. I plugged in the USB keyboard, and it loaded a driver for the\nUSB.\n\nIs there a solution? I suspect MS did not regression test their software\nagainst their own older PS/2 keyboard. Good ideas?
