No device under Win10


Roger 2021/03/24 01:35

I connect NanoVNA V2plus4 to the PC (Win10 64 Home) and get "Device COM5" but I do not see any drive.
When I look at Device COM5 in Properties, it says Device COM5 not migrated.
I have also tried with my laptop, same behaviour.
I have also tried five different USB cables, no change.
What should I do?

Hello Roger,
I have exact same problem on WIN10 Pro 64bit.
The Cypress driver installed without problems and device is shown in "Device Manager". But that COM port for "NanoVNA V2plus4" is not shown on SaverSW, the "serial  port" window remains blank, "rescan" doesn't find anything, independent of Saver SW versions. (I tried version 0.22 and 0.3.8, both 32bit and 64bit version)).

However when running the alterntive Windows "vna_qt.exe" software everything works well. So it can't be any cable or USB-driver issue.

Did you find ayn solution to that problem ?

Try manually entering the COM port name in nanovna saver like: \\.\COM1

OwO,
thanks for the quick reply, but your idea doesn't help.  I also tried on another WIN10 PC, same problem.

CypressDriverInstaller_1:
Driver   Cypress
Date    13.Oct 2015
Version 3.13.0.59

Something strange on both PC:
Device manager / COMport/Driver/ Events...
... Ports\VID_04B4&PID_0008\1&2b53a856&0&00" erfordert weitere Installationen. = *requires addtional installations.* I have no clue what that means ???

But the strange thing is, all works fine with "vna_qt.exe" = VNA View.
I can select \\.\ COM4 and it runs

So I guess the VNASaver SW istn't fully supporting that Cypress chip in the NanoVNA V2plus4 ??

Welcome to the club. I've pretty much given up trying to connect the V2 to
the PC or laptop under WIN 10 / 64. I have the V2N and am unable to
connect to either Saver or QT with the Cypress driver installed in the same
folder. It is recognized on the USB buss, but that's as far as it goes.
However, it's a spiff instrument as a stand-alone!

I managed to get mine to work on both Winders 10 PCs with the saver
software. I have to leave to run a few errands now. When I get back I will
write something up.

Back home, so here is what I did.  I have two Win10 PCs. Both are running WIN 10 Pro. One is a laptop and the other a desktop.

Looking at the laptop first.

Laptop WIN 10 Details:

Version 20H2, build 19042.906. Latest updates:

KB5000842 Update for Windows Package ( I think this was an optional update, and the last one installed. I installed this one before doing what is described below)

10.0.19041.903 Servicing Stack 10.0

KB4601050 Update for Windows

KB4562830 Feature Update for Windows 10 20H2 via Enablement

After KB5000842 is installed reboot the PC and see if that fixes the problem. In my case it did not.  I have not idea if you need this update.  If you don't have it go without it.

When the NANO connects to the PC two items should appear in “Device Manager”. Under “Universal Serial Bus controllers” will be “USB to UART Adapter”. The second under “Ports (COM & LPT)” will be “USB Serial Port (COMx). COM3 in my case. On the laptop, if I recall, I never got the COM port. On the other PC I got a COM port, but the Saver software did not see it. In both cases if you look at driver property it should say “cypress”.

I noticed something else in Device Manager. There was an “Other Devices” listed. It had a little yellow triangle in the icon. In that section was “Virtual Serial Port Device 00”. Right click and select “update driver. You are shown a couple of options as to where to find the driver. Both failed but I was given a third option to look to Windows Update. Found a driver and it installed. I viewed “optional updates” and found a Cypress. Installed that driver and “Other Devices” disappeared. I now had a COM port. I think I did a reboot here also. Connected the NANO. COM port was there. Started the Saver Software. It took awhile to load. It started and it found a COM port. I clicked “connect” and I was good to go. For the laptop that is all it took. For the Desktop, not so lucky.

The desktop:

Installed updates:

KB4601554 Update for Windows

KB5000842 Update for Windows (optional update I installed before starting this)

10.0.19041.903 Servicing Stack 10.0

KB4562830 Feature Update for Windows 10 20H2 via Enablement

KB4589212 Update for Windows

KB4586864 Security update for Windows

KB4570334 Security update for Windows

KB2504637 Unspecified

Installed KB5000842 as above. Rebooted, no luck. Also, I did not have the “Other Devices” in “Device Manager”. I had the “USB to UART Adapter” device so I right clicked and selected update driver. It came back that I had the latest driver. I selected “uninstall” and took it out. If a COM port showed up when the NANO was connected under “Ports”, right click and uninstall that one also. It will be the one with the Cypress driver. Unplug the NANO if it is connected to the PC. Reboot the PC.

Plug in the NANO to the USB port. The “USB to UART Adapter” will reappear. Try to update the driver again using Windows Update. For the desktop system windows update found a Cypress driver. I installed it and rebooted the PC. Device Manager now showed the “Other Devices” with the “Virtual Serial Port Device” in that section. As with the laptop I right clicked and updated the driver via Windows Update. A reboot then reconnected the NANO and started the Saver software. It worked.

How long will this last? Who knows? Until another major update like 20H2 I guess. 20H2 sounds like a virus. Oh wait… Windows is a virus…..

That is the solution!
First: the Crypress drives and installed in Program Files (86)
Second: vna_qt.exe (for Windows) and installed in Program Files (86)

Hi Team,
I also installed the Cypress driver and the .exe for a successful install on my Win-10 Dell Inspiron-15. Just placed the zip file into a new folder in 'Documents' folder - no special location.   Then made a short-cut from the vna_qt.exe to the desktop for launch.

This fix also worked for me (Win-10, Dell Inspiron laptop).  Just needed to make a desktop shortcut for the .exe for convenience.
(Unsure what happened to my previous post on this topic ... )
Cheers,

I am currently using the Microsoft driver 10.0.18362.1.  I tried the Cypress driver 3.13.0.59 and saw no difference so I uninstalled it and went back to the one included with the OS.  I am running 10 Pro 10.0.18361 Build 18362.

I wonder if the problems people are running into started with later versions of the OS or if something else is causing it.

Mike Suhar 2021/04/14 11:47

For me it started with the upgrade of Windows 10 to Version 20H2,  Run "winver" and it will show you your current version.
