Re: No matching id on Details pull down
"Not on mine. Perhaps because it didn't install?" Yes, that's why. Sorry, I meant for you to check one of the controllers that did install. But matching ID isn't important to know at this point
Re: Inf name not on your Details pull down
"All of them, including the one with the yellow triangle, have an entry described as Install Inf and it refers to oem26." Very strange. I can't explain why yours shows Install Inf vs Inf name. I looked at Device Manager Details on both Win10 v1511 and v1607 releases. Both show Inf name for me. But, again, not important as Install Inf shows what we wanted to verify
Re: "I assumed that windows 10 installed its generic drivers during the clean install"
Yes, the MS generic drivers are installed on a clean install.
- But your current situation shows the Intel USB driver installed. It was downloaded sometime after you completed the re-install. (Either by you or Windows update i would think)
- Makes me wonder when it worked before, might it have worked when it was the Windows 10 generic driver installed?
- After the re-install, do you know how/when the Intel USB driver was downloaded? After re-install, do you know if your problem also occurred with MS generics, before Intel USB downloaded and installed
