USB DRIVERS ARE NOT WORKING

HELLO SIR,
I HAVE A PROBLEM WITH MY USB DRIVERS. MY USB DRIVERS ARE NOT SUPPORING FOR MASS STORAGE DEVICES ONLY.
I HAVE OPENED THE CONTROL PANEL FOR USB DEVICES. IT GIVES ERROR MESSAGE THAT, "
Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)
The driver could not be loaded because a previous version of the driver is still in memory."
SO WHAT CAN I DO FOR THIS? PLEASE HELP ME.

Can you check the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE10318}
At that registry key, in the right window, is there a "Name" UpperFilters and/or
LowerFilters?
If so, what is "Data" for those Names?

This question was solved.
View Solution.

What did you plug into the usb port.
Have your tried multiple devices?
When was the last time they worked?
Try removing the drivers in device manager.
Then reboot and let them reinstall
If that fails the try a System Restore to previous date when they did work.
Here is how to do a System Restore

USB Ports are not working in Windows 7

I am on a MacBook and I installed Windows 7 via Bootcamp. It is working amazingly. I love all the new features and the look.
But all my usb devices are not working. I have a external HD and a Zune and a printer plugged in and nothing shows up.
I have tried with my usb hub and without. Doesn't make a difference.
BUT, they do show up in the Hardware and Devices place. Like I can remove them but not explore them.
I have installed all the drivers for bootcamp and everything.
Please help.
Thanks in Advance.
Best Regards,
Luc

"I'm a new mac user and I've just purchased a Late 2009 Macbook White. I updated bootcamp and installed windows 7 on it, and upgraded the boot camp assistant on the Windows 7 to 3.1. but when ever i plug in a Flash drive into the upper slot it does not seems to recognize it and there is no safely remove icon on the task bar, but i am able to see it in my computer. but when i plug the same flash drive to the lower usb slot everything works fine, autorun, safely remove. can any one help me with this problem, is it a Hardware problem or Software problem."
do you have the same problem as me?

Usb drives are not working, usb drives are not working

USB drives are not working. Please help

Non of my Western Digital drives are working anymore on several different Mac computers, one Mac can still work with the drive so I am not getting it up dated to the new OS.
If they told me that all my 2 TB drives would no longer work if I got the new OS I would not have updated.
There needs to be a fix, I can't afford all new drives plus they have video on them that I need to use.
Also iPhoto and Garage Band have disapeared I can't find any trace of them???

Z87m gaming - 2 usb ports are not working

Hello all,
I have just finished putting together a new computer using the z78m motherboard which I am enjoying. I am running windows 64 on it. Unfortunately the two USB 3.0 ports under my lan port on the back panel are not working properly. Everything else works fine. I have installed the latest usb 3.0 drivers off the msi site. The BIOS does recognize those ports and indicates what is plugged in them. I feel like it still might be some sort of driver issue.
In my system information, under components - Problem Devices , it lists Universal Serial Bus (USB) Controller ( error code - Drivers for this device are not installed )
Then in my device manager, listed under other devices, it shows Universal Serial Bus (USB) Controller. When I try to automatically update the driver it says windows could not find one. I was thinking about manually updating it but I am not sure how to properly do that.
There are a few options under USB Controller - Intel(R)
- USB 3.0 eXtensible Host Controller
- USB 3.0 Root Hub
- USB 3.9 Hub
- USB 2.0 ....... etc.
I am not sure how to go about making a selection and I don't want to make my situation even worse. Wondering if anyone how there could point me in the right direction.
Thanks!

HP Pavilion dv6-6b10tx two of the usb ports are not working

I have recently bought a HP Pavilion dv6-6b10tx....and had it fixed by hp for a problem with the beeping noise.
After sending my laptop for repairs( replacing the system board), I received my laptop but two of my usb ports are not functioning...
I did a bios update and did the hp update to see if it actually fix anything but not luck. So I went device manager and found a exclamation mark on the renesas electronics usb 3.0 host controller with a device status 'This device cannot start. (Code 10)'. What do i do??

The question is why is the port not working? Is something in the port that you can see? If not, then there isn't much you can do but take the computer in to the genius bar and have the techs see if it is a circuit problem that can be fixed.

Apple 23" Cinema Display - The USB Ports Are Not Working

The USB ports on my Cinema Display are not working. I do have both Tiger and Leopard installed on my Power Mac G5. Does this issue have to do with Leopard? If so, how can I fix this issue?

I would power down everything, disconnect the monitor from the computer, and the power from the computer and the monitor, wait 15 minutes, and reconnect the power. *Double check* your monitor connections, make sure the USB is properly inserted to the compters USB port. Might try a different port. If the USB ports of the computer work with known working devices (like a keyboard) and the problems continue, it looks like the monitor ports have a hardware problem.

USB ports are not working and I can't figure out what to do!

My laptop is a HP Pavilion dv4-1225dx Entertainment Notebook. I've had it for almost three years now. It is running Windows Vista, the same it came with. The problem has only just recently started or was just discovered.
My problem is that the two USB ports in the side do nothing when something is plugged into them. The metal part of the USB devices gets hot but no lights come on the flashdrive and the camera doesn't act like it is plugged in at all. I've looked through Device Manager and it says they are working fine and the correct driver is installed already. There is also no older driver to rollback to. I've tried deleting them, disabling them, and everything that has been suggested online. I even flashed my BIOS from F.33 to F.55, whatever that means, and still nothing.
Does anyone know how to fix this problem? I am a filmmaker and desperatley need my USB ports. Any help would be appreciated greatly

USB ports must be enabled in order for them to work. If you disabled them it is possible that they still are disabled.
If that is the case, have you tried any of these? http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00820529&tmp_task=solveCategory&lc=en&dlc=en&cc...
By the way, even though Windows XP troubleshooting may not seem to apply to your situation, sometimes these sorts of errors and problems still happen in Windows Vista. It is rarer but it still happens. One Windows XP based solution can be found here: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00035365&tmp_task=solveCategory&lc=en&dlc=en&cc...
Also, take a look at power management settings for your USB hub and/or USB ports. If they are enabled, try going to Computer Management, Device Manager, and then right click on the USB ports and select Properties. Following this, click the Power Management tab and uncheck the option "Allow the computer to turn off this device to save power" and click OK and exit out of Device Manager.
Odd as it seems, sometimes a restart is necessary for this to work completely.
Also, if you have tried removing the USB Hub drivers according to HP methods, you need to make sure that nothing is plugged into the Ports when you remove them. Often, a restart still is necessary even if some techs do not think to instruct you to do so. After a restart, allow the drivers to reinstall--all of them. Sometimes you still will need to restart your computer again afterward. This sometimes takes a few minutes. But, you must in any case make sure that nothing is plugged into the ports.
You may also want to check to see if your computer has specific drivers for your USB ports rather than the generic ones. If so, running the option for restoring drivers in HP Application Recovery will fix this. If they are there you will see the USB drivers listed.
On rare occasion, there is a problem with a device further down the tree than the USB ports and/or USB hubs themselves. These problems are most often fixed by removing the device that controls the USB Hub, such as the devices attached to the PCI Bus and connected to the USB. You will see where these are connected by changing the view to "Devices by Connection" rather than the "Devices by Type" option.
Let me know your status, please, after you have tried these options. If you have already tried them all out, let me know that, too and we can see if there is another option for you to try.

Windows support files - bootcamp, drivers are not working [no sound, keyboard shortcuts]

Hi guys,
I'm using the following version of Bootcamp Version 5.0.3 (464) on MBP mid 2010, wit latest OS on it. I ave installed Windows 7 through multiple errors and had to clean the whole HD after backing the files. The Windows is running fine now, however I think I havent dowloaded Windows Support Files (second tickbox) in the bootcamp assistant when installing Windows (I only ticked the third box).
And now I have tried to download the drviers from bootcamp on USB after formating it correctly, but the USB shows its empty.
I tried the following steps:
I went back into my Mac and opened up Bootcamp, reinstalled all the Windows Support Files (the top box of Bootcamp) and made sure to put them onto an external device i.e. USB/External Hard Drive etc...
I then logged back onto my partioned Windows on my Mac and updated all the Windows Support Files. After that I restarted my computer back into Windows and popped in Guild Wars 2...
But nothing seems to be working. I went to Windows Update smth, and looked for updates found quite a few of them and isntalled all of them, but noting is working - sound and keyboard shortcuts are gone and I cant downloaed the software I want.
Could you please advice on what to do with those drivers. I have been trying for days...

Hi JFFulcrum, thanks for your suggestion. I updated the BIOS earlier and still am getting the same results. Also, I decided to try another old soundcard I had laying around today, a SB PCI 512. And....same result i'm getting with the Audigy. Windows detects both cards, says they're working, but there's no sound. I'm beginning to think I should just RMA the board
if you could find anymore information about those DMA issues, please do post! I have e-mailed gigabyte 3 days ago and they still haven't gotten back to me, so i'm not really sure where to go from here, if it's some setting in the bios, some sort of driver, a bad pci slot or what. ..

Drivers are not working for new BT wifi dongle

I just got BT infinity installed today. I also got the dual band AC wifi dongle 900 But it will not register on my PC. I tried installing the drivers for it but i noticed they are only for the 600 model. I know the Home hub 5 just came out along with the new dongle so is it just a case of waiting for drivers to be realesed?

Hi lightlamp,
I'm sorry about that, check out this link for the AC dongle drivers and let me know if you need any further help.
Cheers
Neil

64-bit Boot Image Drivers Are Not Working

I've been deploying Windows 7 x86 and x64 for years. I've been using the same 32-bit boot image for both and it's been working great.
We've decided to take the plunge and go all x64 moving forward. I want to switch to a 64-bit boot image so I don't have to curate the drivers for two architectures.
I've created a 64-bit boot image, and included all of the 64-bit versions of the drivers in my 32-bit boot image, but they don't seem to be working. I've tried booting 3 different models, but I receive "Failed to find a valid network adapter."
I've looked within the boot image, because I wanted to see the driver files. Either I just don't know where I'm looking, or they're in the "Files" folder where each file is renamed to a number.
What might I have done wrong?

I've solved my problem by downloading and importing the Dell WinPE driver pack. Now I've just got to add the USB 3.0 drivers (I support laptops that don't have optical drives), and I'll be set.
