This is very odd. I've got two laptops and a desktop, each running XP Pro SP3 with a MS Digitial Media Pro USB Keyboard. Yesterday, after moving some stuff around, I connected the keyboard to a laptop (that had used the keyboard before) and I got the Found New Hardware Wizard for MS Digitial Media Pro keyboard. The hardware wizard could not find the drivers and the keyboard would not work. So I downloaded/installed the MS IntelliType Driver, removed the device from Hardware Manager, plugged in the keyboard again and the drivers could still not be found. Then I tried my other MS Digitial Media Pro keyboard with the same results. Then I replugged the keyboard into my other laptop and it also got the found new hardware wizard and could not find drivers. I had been using the keyboard on that machine just an hour before with no problem. I have tried manually specifing that the device is an HID compliant keyboard, but XP says the device will not start.
Summary - two keyboards, two laptops, each was working fine earlier in the day, now neither laptop works with either keyboard.
What could be going on?
