Dell U473D Keyboard stops working

This question is not answered

Computer: Optiplex 980 Win7-64bit

Keyboard: Dell U473D  M/N: Y-U0003-DEL5

If I unplug the keyboard and plug it back in, it stops working. If I unplug it and replug it into a different USB it will work, if I plug it from that USB it will not work from both USB ports.

It might need a new driver.

I tested a different keyboard (DELL SK-8115) and it worked all the time no matter how many times it was unplugged.

Is there a keyboard driver or some USB driver that's needed?

  • I have noticed the same thing.  I love this keyboard so I'd rather not replace it.  I did notice that you can also get the keyboard to work again if you go into device manager and uninstall it.  There are two instances of the device for some reason called "HID Keyboard Device".  I uninstall both with the keyboard plugged in, disconnect from USB and reconnect to same USB, the keyboard autodetects and reinstalls again... then it works.  It always shows two instances of the device though... I am sure that is causing a issue somehow.  Can anyone help?

  • Actually, I just messed with it a little bit more and found you don't have to unplug and plug back in.  Just uninstall both devices then right click on the category the device is under "Keyboards" and click "Scan for Hardware Changes".  You may have to do this more than once but after doing that at least once or twice the keyboard detects again and auto installs then starts working again.
