What is oem42.inf and why doesn't it install?

In response to Computer Geek (thanks), here are the two files requested. I can't point you to the driver I'm trying to install because it's not listed (I guess because it won't install). The error message implies it's an Intel USB Controller driver but you will notice that there is a driver already installed for that. The USB ports seem to be working fine except I couldn't get the Line 6 drivers to recognise my device (it's a UX1 sound card for playing the guitar through the computer sound system). I talked with Line 6 but they say there is no incompatibility problem with Windows 10. This may be a red herring.

pnp.txt
DxDiag.txt

oemnn.inf is just a naming convention Windows uses when installing a 3rd party driver (more specifically, a 3rd party driver that wasn't included on the original Windows installation media). nn is just the next sequential number appended to oem when the driver is installed and the filename created

The error message implies it's an Intel USB Controller driver but you will notice that there is a driver already installed for that.

Yea, that error message also has me a bit confused as it seems to indicate oem42.inf was an attempt to re-install what pnputil shows as oem26.inf (Intel USB controller driver with same version number and date as oem42)

You say all your usb ports currently work. Look in Device Manager, are there any devices with yellow icons? Also, am curious, right click one of the USB controllers->Properties->Details tab. Use the pull down to select Matching Device Id. What does it show?

Also, your Gigabyte EP41-UD3L mobo is a bit old and doesn't appear certified for Win 10 which may be the root of your Line 6 problem.

Will look at it more sometime tomorrow

Well, i've been looking for drivers and getting nowhere fast. Maybe EdTittel will have better luck then I.

• You said this was a clean re-install. Does that mean that controller was working before under Win 10?
• Have you tried just right click the controller in Device Manager, select Update Driver?
• Windows 10 comes with its own generic driver for the USB controller. Had you checked if the USB controllers and ports worked with the windows 10 generic driver?

As to your processor question, can't answer. I'm more of a software guy :) Maybe one of the others can

btw.... Don't think still needed at this point, but when I asked earlier about "Matching ID" that's an actual selection in the Details pull down menu. It tells you which one of the hardware IDs Windows used in selecting the driver it chose. Can tell you have specific or generic a driver Windows selected for a device.

One more thing, to be certain. Select one of the installed controllers->Properties->Details tab, select Inf Name on the pull down menu. Verify it does say oem26.inf .?

Yes. The earlier install was the upgrade from 8.1. Worked fine.

• Have you tried just right click the controller in Device Manager, select Update Driver?

Yes, did that first.

I assumed that windows 10 installed its generic drivers during the clean install.

Not on mine. Perhaps because it didn't install?

There are 4 entries titled Universal Serial Bus (USB) Controller. All of them, including the one with the yellow triangle, have an entry described as Install Inf and it refers to oem26.inf. There is no entry titled ​Inf Name.

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

Hmm. Interesting. As I recall, the clean install went fine but then I had to manually install a couple of devices. The Line 6 was one and it failed. Can't think of any others. Of course I reinstalled a bunch of software but the wouldn't be the cause would it?

Is there a way to uninstall the Intel USB driver, delete it and allow Win 10 to install the generics? Would that be worth a try?
