Welcome to Microsoft Answers forum.
I would suggest you to run the hot fix and see if that helps.
If your high-speed USB 2.0 ports don't work, you might not have the correct driver installed for the ports in your computer, or the ports might be defective. If you are using an external USB hub plugged into your computer, this might also be defective or lack the proper drivers. Check Device Manager to see if your USB ports or hubs are working properly.
1. Open Device Manager by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
2. Double-click Universal Serial Bus controllers and check to see if all your USB ports, hubs, and controllers are functioning correctly. Any devices not functioning will have a yellow exclamation mark in front of them.
3. If Device Manager shows any USB ports, hubs, or controllers are not functioning, check for updated drivers. For more information, see Update a driver for hardware that isn't working properly.

if the above method fails I would suggest you to delete upper filter and Lower filter, the following steps will help you to delete the filter.
REGISTRY EDIT DISCLAIMER:
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

4. Locate and then click the LowerFilters registry value. This value is located in the following registry subkey:
5. On the Edit menu, click Delete, and then click OK.
6. Exit Registry Editor.
7. Restart the computer.
Note If you remove both registry values, and then you lose functionality in a particular program such as CD recording software, you may have to reinstall that software. If this problem occurs again, contact the software vendor for help.
Hope this helps. Let us know the results.

The advice regarding Method II from Vijay B left me unable to boot, even after restoring registry backups. Way to go mate. I have tried literally every possible method of resolving this situation, which has plagued me since Vista...
Nothing has helped at all. The only thing that did work was disabling the usb hosts and having them revert to usb 1.x, which is unacceptable. Man up and admit that this MS' shenanigans. Many people are having this same problem, and it's about time we got some real answers. Yes, I have tried all of the hotfixes suggested on this site (and pretty much every other one out there). Yes, I have tried uninstalling all of the usb hosts in the device manager. Yes, I have left my PC off for a while unplugged. None of this helped, and finally an answer from someone associated with MS leaves my Windows 7 install unable to boot, so much so that registry backups didn't even help apparently.
I find myself endlessly frustrated with this situation, and even more so that I probably have to reinstall my OS, only to have the usb ports fail once again.
The blue screen error is STOP: 0x0000007B (0xFFFFF880009A9928, 0xFFFFFFFFC0000034, ...)
Yes, I have checked to make sure the mode is IDE. No, I will not format when all of my files are openly accessible through the repair option on boot.
As expected, even after a full reinstall of Windows 7, the USB issue persists...
I join the ranks of the frustrated. Although I'm not suffering from the BSOD and can boot into Windows 7 successfully, I have an unstoppable pop-up that claims that: "One of the USB devices attached to this computer has malfunctioned, and WIndows doesn't recognize it."
There is no device connected to my machine, yet there is a USB port that doesn't work anymore. I can't uninstall it since it keeps reappearing on startup and yet it just reports an "Unknown Device" that needs troubleshooting.
Click on the Unknown Device and get this in the properties window: "Windows has stopped this device because it has reported problems. (Code 43)" No device, nothing stopped and unable to stop the most annoying popup that continues flashing in the notification / task bar until I open it and keep it open for the duration of my session. My problem may be different in that the death of an actual USB port could be to blame. But I too have tried all the suggestions including rewinding to a restore point, HijackThis, etc. etc.
I keep glancing over at my gorgeous Ubuntu 10.04 laptop as I grumble along with Windows 7 (Home Premium) problems and feel like I might just snap at any second, scrub the boot and escape from proprietary software license land for good. I hardly play the heavy processing games anymore anyway, which is the only reason I refrain from the permanent move.
It looks like your problem is similar, but differs from the original question. Please start your own question and provide the details of your problem so that we can help you further.
