Try plugging the device into a different USB port, preferably a port
using a different USB controller on your computer. (For example, if the
device is plugged into a USB 2.0 port, try a USB 3.0 port, or vice
versa). Wait a few seconds and with luck you may see a quick popup
message saying that Windows has loaded the driver and the device is
ready for use.
I had a similar problem a couple of days ago on my Windows 10 Pro
computer. The external USB audio device I use for data comm showed up
fine in Device Manager and all the drivers showed as current and
working. Yet, WSJT-X and other software triggered a popup message that
they couldn't connect to the device. Switching ports fixed it. After
that, I put the device back on its original port and the "loading
driver" message popped up again and its working fine where it was.
If my suggestion doesn't work, you may need to uninstall and install
again. I wanted to avoid that because my external device also operates
four USB-to-RS232 comm ports and they are always a pain to reload and
fix the comm port assignments.
