Windows 10: Updated to Win10 version 1909 - now USB serial converter does not function

Updated to Win10 version 1909 - now USB serial converter does not function.


The 'ports' section of device manager has been removed in this version of windows, and the application I am using requires a COM port be associated with a USB device. Keyspan USB to Serial adapter - USA-19H


How does one go about adding a COM port to a USB device? I have attempted to 'add legacy device', however, nothing returns for USB Serial device. Also, there is no 'port' tab in the properties of these USB devices.

Windows 10 serial on OEM


So I'll summarize steps made...

1. Saved serial number (taken with Belarc Advisory) from preinstalled (half chinese language) Windows 8.1 (don't know exactly the version, suspect Windows 8.1 with bing) on tablet
2. Formatted tablet
3. Tried to make a clean Windows 10 (HOME, HOME N and also PRO, everytime with the same result) install with ISO taken with MediaCreationTool, during install (and also after completing installation) it says that the saved serial is not valid
4. Tried to reinstall Windows 8.1 (ISO taken with MediaCreationTool again) HOME, it says that the serial is not valid

So i suspect that the saved serial, is from a WINDOWS 8.1 WITH BING OEM version and this kind of ISO is not accessible/downloadable anywhere (at least I can't find it, any suggestion?)

Still not tried SHOWKEY with that serial, I am in office now, and the serial is saved on a usb pen at home, will try this evening.

So I'm stucked but if everything is like I suspect, it's incredible. If I have a tablet/notebook/netbook with Windows 8 preinstalled, it seems that I can update to Windows 10 without problems, but if I want to make a clean Windows 10 install that serial is not valid...

Serial Mouse via USB not detected


Hi,

I have just installed Windows 10 and my mouse no longer works. Its a specific adapted mouse (for disability) that connects via Serial (9-pin) into a Serial-USB converter cable. The converter cable gets detected ok (as Prolific Serial-USB Adapter) but the Serial mouse running on the end of it doesn't work/get detected.

In Windows 7 it works fine and needed no addition drivers other than the the Prolific adapter. Can I tell if Windows is detecting its presence? Any suggestions?

Cheers,
Russ,
