Hi everyone. Anybody run into a problem with windows 10 connecting to
SAA-2N (20200926 FW) after installing the latest Windows feature
update ver 2004? This update just came through this morning and I ran
it. Now the SAA-2N shows up in Device Manager as "System
Devices-Universal Serial Bus Controllers-USB to UARP Adapter" with the
Cypress driver, but it does not assign a COM Port as it previously did
before the update, when all operation was normal.. NanoVNA-QT will, of
course, not connect. Tried it on my WIN 7 machine and all is normal.
Tried my H4 on the Win 10 machine and it assigned a COM port as normal
with the MS Driver.
Maybe a driver issue? Any suggestions?
THX....Ted (KD7AQO)

Hello, I had that problem a few days ago and not even reinstalling the
driver was solved.
What I did to solve it was to replace the driver already installed by
the ZADIC libusb (in CDC mode). With this everything worked again.

Greetings

Yes. I cleared this exact problem last week for my V2. My windows built
a new "Unknown Device" in the Device Manager list.

I did a refresh the driver in this device and it gave me a good COM-6
with the Cypress driver installed.

I hope this helps.

THX Juan and John for the quick replies. I'll give it a try and see what happens.

Worked fine this morning, then I updated win 10 and the problem shows up. Typical windows I guess.

YEA!!!
Had two "unknown devices" in Device Mgr. First one, I tried to update
the driver with no luck, but on the second one, update driver worked,
unknown device cleared, and when connecting the SAA-2N, picked up COM
8. Everything now works OK.
Many THX.
