Based on that, the unknown device is not your mouse since the PIDs are different.

I had that problem once before and it turned out to be a card reader, which I never use, that required a driver reinstall.

Did you try comparing the PIDs for your card reader to that of the problem device?

I know what you mean. I can't find mine listed in Device Manager and I don't have any cards to insert into it. I only asked since your reply sounded like it might have been the problem.

A Card Reader should show in its own separate node, in Device Manager, named "Memory Technology Devices". Unless, say for example, you have an Card Reader integrated into the computer, and it is switched off in BIOS.

I didn't check the BIOS. However, the device was installed by the vendor (cyberpowerpc). When I install the driver disc in my G: drive (CD-ROM) and tell Windows to open the disc, it shows the device as drive F:. Drive F: is not shown in Windows Explorer but it is shown when I run msinfo32 as a CD-Rom drive.

Thanks. I wanted my system to be good for 10 years so I added a bunch of things when I ordered it. Turns out, 11 years later, I have never used the floppy drive or the card reader.

Look forward to what you find.
