Device Driver updated a different MS package this time after reinstall
I installed 1909 from 1903 and then my All in One printer stopped working. It's a non-compatible Lexmark Pro700 Series inkjet. I've used the printer in Windows 10 ever since the new desktop OOBE purchase. It's always been connected via a USB cable and worked fine. Lexmark got out of the inkjet business a long time ago so they don't support updated drivers.
The first time that I actually ever had a problem with the printer not working occurred after installing version 1903. To get it working again on 1903 didn't take any real fiddling. I have to assume it became working again due to a Microsoft driver package automatically installed by Device Driver via Windows Update. I'll explain my reasoning.
After installing 1909, Device driver updated the Driver Store with a different Microsoft printer driver package. How do I know this? From what I noted in the Driver Store while I was still on 1903. The Microsoft driver package had an "identification", for the lack of a better word, to describe the INF which was different than what the identification is that’s installed now.
The Microsoft printer driver package in the Driver Store showed the package identified as prnms066.inf. After installing 1909, I removed the printer, uninstalled all drivers, and re-installed the Lexmark software and drivers. I attempted every method that can be followed in the book when trying to re-install the printer and get it working in 1909.
I believe the Microsoft driver package - prnms066.inf is the correct one. The MS package that installed this time however is identified as prnms006.inf. Catch the difference? Look at the numbers. No, I did not make a mistake when I wrote down prnms066.inf while on version 1903.
I spent time searching in Windows Update Catalog using every search phrase I could come up with for this MS driver package. Without knowing the version number makes it a little harder, and I have only been able to find the prnms006.inf file on the Update Catalog website.
Yesterday, I uninstalled version 1909. The reasoning was that if Device Driver installed the working driver package in 1903, it might again. Incidentally, the printer began showing up in Control Panel -> Devices and Printers as "Unspecified" with a small generic looking icon after going to 1909. The same with my USB external HDD. I'm currently on 1903 now and nothing has changed in regard to this thing that others are experiencing too where USB connected devices show as 'Unspecified".
I'd greatly appreciate some direction here. Sorry about the long post
