RE: USB Keyboard Hangs/Quits working on XPS15 9550 and Thunderbolt Dock TB16 . W10Pro x64
What version of Citrix Receiver? And if it’s at least 4.9 (which confusingly shows as 14.9 in Programs and Features....), did you update that before installing the ASMedia driver? Older versions can interfere with installing, updating, or even uninstalling that driver. There’s a Dell KB article about it.
