Yet another Western Digital My Passport driver problem

ComputerGeek, I really thought you had it! The composite driver was indeed missing (although usb.inf and usb.pnf were still there). Also missing was a driver called usbhub.sys. I placed both the files back into the system32 folder, and rebuilt the inf cache file. Unfortunately, I'm still getting the same error, as in drivers are not found and the drive shows under Other Devices with the yellow exclamation mark in Device Manager. Okay, I'm going to try another couple of things and report back. Thanks for the help!

Well, back to the drawing board, I guess. Maybe I'm missing an .inf file somewhere? I saw a suggestion on another forum to point the drive to the File Repository in the DriverStore itself but that didn't work either. Then I tried another sfc /scannow in an elevated command prompt and that gave me a clean bill of health.

Although all other USB devices are working just fine, I'm thinking maybe I should reinstall the motherboard USB drivers. Any thoughts? Appreciate everyone's help, thanks again.

Hey janitoronmars,

I just remember when I had similar driver problems that I used to use the Last Known Good Configuration tool for Windows. If you just remember when was the date that the driver worked for the last time. You could set a date prior to that.

Good luck.

I was just having slowness issues which is why I thought reinstalling all the drivers (regular Windows and the WD SES) would maybe make a difference. The drive was copying data at the same speed as USB 2.0

I have a WD My Passport Essential 500GB, USB 3.0, and it has always run at USB 2.0 speed through USB 3.0 ports. I'm pretty disappointed as it was out of warranty before I got a computer with USB 3.0 ports. If this is a common issue with these and they're just cheap and nasty, like cheap USB thumb drives that run slow, I don't know.
