External USB Keyboard not recognized - Suspect Driver problem

I have a 10 year old Lenovo X220 laptop that I upgraded from Win 7 Pro to Windows 10 Pro last year. I recently upgraded RAM from 4 to 16 Gig and replaced the original HD with a Samsung SSD. The SSD migration had no problems and I'm enjoying a much faster boot up and improved performance.

The only problem is my external usb keyboard has stopped working. The internal laptop keyboard and scratch pad work fine. Before the SSD and memory upgrade I was able to plug the external usb keyboard into any usb port on the dock and it worked fine. I've tried plugging the usb keyboard into every usb port on the docking station when docked and on the laptop (undocked) and none of them work with the keyboard. All of the X220 usb ports can read and write to usb thumb drives.

I've tested this same usb keyboard on my desktop and it works fine.

Reading some other X220 forums, I've used the Windows Device Manager to delete the Standard PS/2 Keyboard from the Keyboard folder, and I've deleted and reinstalled all of the USB Hubs and Controllers in the Unversal Serial Bus controllers folder. Still won't recognize the external usb keyboard.

I opened Windows Devices and Printers and I notice that it shows the external usb Lenovo Black Silk Keyboard when I have it plugged into the usb port. It's listed in the unspecified frame as shown on attached screen shot. But the keys on the usb keyboard still don't type. Adding to this madness, this icon goes away when I unplug the keyboard.

As before, this keyboard still works in other PC's and all of the usb ports on the X220 work with other usb devices like memory sticks. When I right click on that unspecified device here are the properties. Note error, device not migrated.

Any help would be appreciated.

you might try
check to see what it says about the device in the device manager when it is attached to the other computer where it works
or
In device manager right click on on the usb mobile device (seen above) choose update driver
choose "browse my computer" then "let me pick" uncheck "show compatible hardware" scroll down the list to the company and look for the keyboard.
If you don't find it try microsoft/ hid-compliant consumer device or usb input device
one of them might work.

Considering the age of the laptop probably hardware failure or gone out of spec as regards chipset which provides the USB hubs.

You should also try fixing from the regedit, Once my keyboard way also not connecting to my PC and was showing the Driver issue but it wasn't fixing from there so I tried editing the regedit and it worked. So try searching about fixing keyboard driver issue from the regedit and your problem will be fixed.

After comparing the drivers in windows/system32/drivers between my desktop and the laptop, I noticed that many of the drivers in the desktop (including keyboard drivers) were prefixed by avg*. Then I remembered I had removed my AVG antivirus from the laptop when I installed the SSD.

Once I reinstalled AVG on the laptop the external usb keyboard started working.

Thanks,

Glad you got it going.
Why would your antivirus be the problem, confuses me unless you had a nasty virus or AVG
has some protect mode for drivers.
My knowledge of avg is limited , I use norton.
