USB/External Harddrive Not Accessible..

Hi guys, hoping you can help me, this is really driving me mad.

I currently cannot plug in any USB sticks or my external HDD to my PC. This has been going on for a while, but I lost my old USB which worked fine but now everything I try these days just do not work. Have tried multiple different USB sticks and my external HDD.
Also, if I try to put my mouse/keyboard into a different USB port, neither will work either, they have to be in the specific ports they are in now or they just won't function.

What is strange is the fact that all these devices are recognised by my PC (the usb/external HDD). I can see them in Device Manager/Safely Remove Hardware when they're in any port and the drivers will install perfectly.

I have tried so many fixes and none seem to work, so asking you guys is my last shot. I need to create a back-up for my files (100gb worth) but can't get my external HDD to show up.

Here is a list of the things I've tried:

1. Reinstalling drivers.
2. Updating/reinstalling mobo chipset.
3. Deleting Upperfilters and Lowerfilters registry entries.
4. Uninstalling/disabling USB drivers in Device Manager (doing this completely broke every USB port and I had to system restore to a couple of days ago).
5. Tried to change/assign drive letters/paths in Disk Management. I get the error "The operation failed to complete because the disk management console view is not up-to-date. Refresh the view by using the refresh task." etc. Refreshing doesn't work, neither does restarting and all that jazz.
6. Have tried the Microsoft USB fixer, was completely useless.
7. Have tried uninstalling all Unknown Devices incase they were causing problems.

Really run out of options here.

Would appreciate any help you guys could possibly give me.

Thanks a bundle.

  1. You can try this, plug in a PD, bring up CMD and type : chkdsk X: /f/r (X is the drive letter, yours may be different)

    OR, a data recovery software : http://www.cgsecurity.org/wiki/PhotoRec

    OR, http://download.cnet.com/Zero-Assumption-Recovery/3000-2248_4-10061981.html not free.

    OR, find a friend with a PC and take out your HDD and backup everything there, then clean install the OS.

    OR, run some online virus scanners.
  2. Hi Lonewolf, thanks for your reply.

    It's not a case of data recovery. None of my files are lost. I can still access my PC fine, my original HDD is in working condition.
    It's a USB issue; no flash drives or newly plugged in peripherals seem to work, despite showing up on Device Manager and their drivers being loaded and installed.
  3. I would go into BIOS and set optimized defaults.

    Tried it that just now Spooky, but to no avail.
    Tried booting into safe mode too, again, didn't work either.

    I knew it that its not a data recovery issue, so I told you to do a clean install of OS, but you missed my point. Sometimes when the OS got corrupted this things can happen, or there are some virus issue. So do a clean install of OS.

    Another thing you can try by uninstalling all USB root hubs under device manager, restart PC, the USB root hubs drivers will automatically load, now try some USB device to see how it goes.

    Worst case scenario the USB ports on MB has died, but its unlikely.
