We just acquired 7 new Dell Optiplex machines with Vista 64 bit installed. We installed all of our tools and applications on one of the machines and then used Norton Ghost to deploy to the other 6 machines. We have found that the ghosted machines do not recognize any USB keyboards at all when booted into Windows.
The USB mice work fine. We tried all of the 6 different USB ports with both keyboards and mice; the mice work on all 6 ports but the keyboards do not work on any of them.
All these keyboards work fine on other computers. They work in the BIOS and when booting off the system restore disc to run the recovery tools / repair / restore / reinstall options, just not at the main Windows login prompt or beyond. The same behavior occurs in safe mode as well.
We initially thought that this was limited to a keyboard/USB issue, but it seems to be deeper rooted than that. If we use the on screen keyboard to get past the login prompt we are just stuck at a blank screen. Just the default blueish background wallpaper with no shell, no ability to used the on screen keyboard to bring up task manager or anything like that.
Any ideas what the problem might be or how to proceed?
