USB not recognized, but disply and drives connected work, keyboard does not.

I’ve had my 3900 for some time, today when I plugged it into my laptop running windows 10 a get a USB not recognized error. The display and external drives plugged into it seem to work fine, the key board does not. I have uninstalled and reinstalled with new driver from website. Still same error. USB keyboard does work if pllugged into laptop, but not if plugged into plugable…it used to work.

Thanks for getting in touch!
