DA100 USB device not recognized
 

A DA100 is getting the "USB device not recognized" message. It is the only USB device getting this message.

The Dell laptop is XPS Windows 8.1. I installed DisplayLink USB Graphics Software for Windows. Are there any other drivers to use?

Hello,

"USB device not recognized" is not a fault of the driver but the device as it states.
Unless Windows knows what device is connected, Windows will not know which device driver to assign to it.

I recommend you contact Dell, the manufacturer, to discuss a replacement.

Kind regards,
Alban
