Thanks. Device Manager did not show the IDE controller you quoted but there was another one there (C200 from memory). I uninstalled that, which stopped access to my windows drive on reboot. So I did...

I recently installed a new mobo. I rebooted with the existing version of Windows 10 x64. Since then I occasionally get a BSOD caused by iaStorA.sys. I know this is part of Intel's RAID setup, but I...

Well that was interesting. Look at the attachment. Those Intel drivers are tenacious. However, things do look better for the moment. There wasn't an Intel uninstaller in my list, so I tried to...

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...

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...

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

Thanks for the explanation. Always learning! It used to be complicated enough when I just had an Atari 400 and a cassette recorder!

Yes, there's a USB Controller with a yellow icon. That's the...

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...

Think the water's a bit deep here. I ran the 2.6.2.3 version of Driver Update Utility from Intel. It tried to update my drivers from 9.xxx to 10.xxx. It failed, reporting an "unknown error". But I...

Not that smart. I did backup all the user files (which has proved useful). I'm guessing the way forward would be to uninstall the rogue entry. Then unplug all my USB connections and add them back one...

After a recent clean re-install of Windows 10, there's a USB Controller device that is reporting itself unable to configure. The Events list reports:
Device not configured (oem42.inf)

Hi Ed,

Thanks for the advice, but that didn't fix it. Here's a snip of my Device Manager.

I've discovered these entries appeared when I attempted to install my Logitech Unifying Receiver....

After a clean installation of Windows 10, I get a series of Unknown Devices listed under "Other devices." When I run the update drivers option I get the message seen in the attached image.

Thank you all. I understand much better now. Thanks especially to L Miller 7 for a very helpful and clear explanation.

Ahah! No, it creeps up over 4.7GB 57%. So I guess nothing else I'm doing needs the extra ram.

Good thought, but no. About reports installed RAM as 8gb and System type as 64-bit operating system, x64-based processor.

I have 8gb ram memory. System info shows it all. Performance monitor shows that I use up to about 3.5gb, but never more. Is that normal?
