USB Mass Storage Device - Endless Loop

By hamilton456 ·

I installed Windows Vista and it worked fine for about a day. Now it keeps seeing a USB Mass Storage device that isn't there and then it alternates between seeing it and not seeing it. It happens so frequently that my games can't run smoothly and when I'm just working with other applications, the sound of it seeing the connected hardware happens so frequently it's annoying. I can remove it with the Safely Remove Hardware utility, but then it just appears over and over again. I believe this may have something to do with a Western Digital My Book backup drive that I had connected and then accidentally disconnected. The problem is that it keeps seeing it even though it isn't plugged in anymore. How can I get rid of this phantom?

I have also tried uninstalling it from the Device Manager screen (when it stays around long enough for me to select that option), but it always comes back.

Don't ya just hate the ghosts?

Try plugging the WD My Book back in, letting Vista complete the found hardware and get it installed, then use the safely remove hardware wizard to remove it properly and unplug it afterwards. "Back in the old days", we had to do this with floppy disks that were removed from the drive while looking at it and before the drive was properly closed (loot at some other drive). Windows would keep looking for the floppy. Vista may have had a file open on the My Book and is looking to close it.

Try this to show phantom devices

I know this works for XP. You need to get to the enviorment varibles and add this string.

"devmgr_show_nonpresent_devices" (don't type the quotes) and set the value to 1. Then in device manager, make sure show hidden devices is checked. Now you should see a bunch of ghosted devices. If you uninstall those, you should be good.
