USB port not working

[notaguru]

SP3, SP4 keyboard, W10, Windows Defender is the only AV, no tricky software

My one-and-only USB port provides power, but does not "see" common USB devices (external drive, digital microscope, etc.). Those devices work properly on another computer. I really need that digital microscope, which is claimed to be Windows 10 compatible!

Control Panel > Device Manager produces only one yellow exclamation point: UTAX WIA Class Driver. No update is available.

I wiggled the connector.
I examined the interior of the female USB port (with the digital microscope connected to another computer) and see nothing unusual.

Have you tried deleting that entry and restarting?

Your devices might draw more power than 900ma. Try using a powered USB hub or USB Y cable Connected to a USB power port.

Deleted the UTAX WIA entry, restarted, found UTAX WIA missing. I deleted the software for a digital microscope (400mA total draw) and restarted. Reinstalled, and the device appears as USB20 Camera with a yellow exclamation point. It wants a driver, so I tried to find it online and on my machine. The vendor of the device will try to help.
