Windows 7 Mouse and Keyboard Stopped Working

[jay a]

Hello

I bought a brand new MICROSOFT NATURAL KEYBOARD 4000 to replace the exact same keyboard that's a few years old. Something went horribly wrong. The keyboard and the mouse no longer work, together, individually, or combined with other keyboards and mouse.

The computer no longer recognizes the MOUSE or the KEYBOARD. Device manager shows that they're plugged in as OTHER DEVICES, but it can't install the driver for them. I've tried installing the 4000 drivers, but that's shouldn't be necessary. The installation goes fine, but still, it only shows up as an OTHER DEVICE.

The thing in common is that they are both input devices, and neither work in Windows. The keyboard works in the bios just fine. If I remove all the USB Controlleres and Ports from device manager, and reboot, the mouse and keyboard both work at the login screen until the ports and controllers are rediscovered and reinstalled, then they both stop.

Event Viewer shows things like this:

INPUT.INF exists in c:\windows\inf. I've tried manually updating the drivers pointing to that folder, but that didn't work.

It seems to me that some core piece of windows is suddenly not working. How can I fix this without reinstalling windows? Are the basic input drivers somehow missing or currpt?

I boot the Windows 7 installer from a usb drive. Unfortunately, the USB drive was C and the windows drive got pushed out to E, so I didn't want to try reinstalling that way with the letter incorrect.

Thank you for your help.

UPDATE: Other devices work in the same usb ports (ie: the flash drive). The mouse and keyboard don't work in any of the usb ports; 2 on front 6 on back.

It seems like you're facing an issue with your new Microsoft Natural Keyboard 4000 and mouse not being recognized by Windows properly. The devices appear in Device Manager under "Other Devices," and you're encountering driver installation problems. Here are some steps you can take to troubleshoot and potentially resolve this without reinstalling Windows:

Troubleshooting Steps:​

1. Check USB Ports:
   • Verify if other USB devices work in the same ports where the keyboard and mouse are not functioning. This helps to determine if the issue is with the devices or the ports themselves.
   []Driver Installation:
   • Ensure that the drivers you are trying to install are correct for your operating system. Additionally, try manually updating the drivers from the Device Manager.
   []USB Controllers:
   • Since removing USB controllers temporarily restores functionality, there might be a conflict with the USB controllers. You can try updating or reinstalling the USB controller drivers.
   []Check BIOS Settings:
   • Confirm that USB functionality is enabled in the BIOS settings. If the keyboard works in the BIOS but not in Windows, there might be a setting affecting USB devices.
   []Windows Update:
   • Make sure your Windows operating system is up to date. Sometimes, Windows updates can resolve driver-related issues.
   []System File Checker (SFC):
   • Run the System File Checker tool to scan and repair corrupt system files that could be causing driver installation issues.

     Steps to Run SFC:​

   []Press Win + X and select Command Prompt (Admin). []Type the command: sfc /scannow and press Enter. []Wait for the scan to complete. If any issues are found, SFC will attempt to repair them.

   Additional Note:​

   • Regarding the drive letter change during the Windows 7 USB boot, this can happen due to the order in which drives are detected during the boot process. The drive letters can be reassigned but should not impact the installation process. By following these troubleshooting steps, you may be able to identify and resolve the issue with your keyboard and mouse not being recognized properly in Windows. If the issue persists, further diagnostics may be required to pinpoint the exact cause. Let me know if you need assistance with any of these steps or if you have any other questions.
