Unable to install any USB devices

Difusal, you are an absolute Genious...Your instructions worked like a charm. You just saved me 5 hours of boring OS reinstallation and apps reload for a user. Thank you Sir!

1000 Thank's :)

I spend more than a week trying to sort this out, nothing was working except your solution!!!

Just like others, I just joined to say thank you.

Thanks a lot Difusal for this useful workarround!!! It works for me too... :)

Kind Regards
Hacene

I had to sign up just to thank you Difusal. It worked and no reinstall (reinstall is not a fix in my opinion). For those of you who it didn't work for your problem is NOT the same as OP. Problem. My problem: no new drivers or USB devices recognized. Old USB devices previously recognized still worked. If I uninstalled the driver of a previously working usb device. Reinstallation and detection would fail. Thanks again Difusal.


Cheer!

Unfortunately I had a similar problem in which my Toshiba Satellite L850 laptop simply stopped recognizing my devices and acting as if I had not even plugged them in. I have tried every solution listed in this thread thoroughly and still nothing has worked. What's worse is I cannot reinstall Windows since my laptop did not come with an OEM disc for some reason. Is there any possible solution to this at all?

Polite bump, I would really like to know if there is any possible solution to my problem. The one suggested on the first page did not work unfortunately.

I tried Difusal way but it didn't work for me, than I pull out battery and again didn't work and I had finally found a solution. Follow steps bellow, i founded on other site.
How To Delete the UpperFilters and LowerFilters Registry Values

1. Click on the Start button.
   If you're using Windows XP, also click on Run.
2. In the search box (Windows 7 and Windows Vista) or the Run textbox (Windows XP) type regedit and click OK or press the ENTER key.
   This will open the Registry Editor program.
   Important: Changes to the registry are made in these steps. Take care in making only the changes outlined below. While it's not a necessary step to complete this process, I recommend that you play it safe by backing up the registry keys you're modifying.
3. Locate the HKEY_LOCAL_MACHINE folder under Computer/My Computer and click the |> or (+) icon next to the folder name to expand the folder.
4. Continue to expand folders until you reach the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class registry key.
5. Click on the |> or (+) icon next to the Class key to expand it. You should see a long list of subkeys open up under Class that look something like this: {4D36E965-E325-11CE-BFC1-08002BE10318}.
   Note: Each 32-digit subkey is unique and corresponds to a particular type, or class, of hardware in Device Manager.
6. Determine the Correct Class GUID for the Hardware Device. Using this list, find the correct Class GUID corresponding to the type of hardware that you're seeing the Device Manager error code for.
   For example, let's say your DVD drive is showing a Code 39 error in Device Manager. According to the list above, the GUID for CD/DVD devices is 4D36E965-E325-11CE-BFC1-08002BE10318. Once you know this GUID, you can continue to Step 7.
7. Click the registry subkey corresponding to the device's Class GUID that you determined in the last step.
8. In the results that appear on the window on the right, locate the UpperFilters and LowerFilters values.
   Note: If you don't see either registry values listed, this solution isn't for you. Double check that you're looking at the correct device class but if you're sure you are, you'll have to try a different solution: How to Fix Device Manager Error Codes.
   Note: If you only see one or the other value, that's fine. Just complete Step 9 or Step 10 below.
9. Right-click on UpperFilters and choose Delete.
   Choose Yes to the "Deleting certain registry values could cause system instability. Are you sure you want to permanently delete this value?" question.
10. Repeat Step 9 with the LowerFilters value.
    Note: You might also see an UpperFilters.bak or LowerFilters.bak value but you do not need to delete either of these. Deleting them probably won't hurt anything but neither one is causing the Device Manager error code you're seeing.
11. Close Registry Editor.
12. Restart your computer.
13. Check to see if deleting the UpperFilters and LowerFilters registry values solved your problem.
    If you've completed these steps due to a Device Manager error code, you can view the device's status to see if the error code is gone. If you're here because of a missing DVD or CD drive, check Computer or My Computer and see if your drive has reappeared.
    Important: It may be necessary to reinstall any programs designed to utilize the device you've removed the UpperFilters and LowerFilters values for. For example, if you removed these values for the DVD/CD device, you may have to reinstall your DVD burning software.

Thank you--you're a lifesaver!

Four and a half years on and you are STILL saving people. I had the issues this morning on a new installed refurb but your guide saved me.
Thanks a million and more.
