usb device not recognized in windows 7

Anonymous

So it seems MS has a problem with " usb device not recognized in windows 7 ". A Google search will find no real solutions to the problem. I haven't found one hear ether. How can I have a handful of flash drives and external hard drives that will not work on only 2 Win7 systems that I know of ,yet work on others ? I never needed to download drivers from anyone to make them work on any other OS . I just plug them in and the work ... THE 1st TIME... not after trying all things that don't. This is something that needs a REAL FIX. I should not have to pay Tech Support to find out why. This is clearly an OS Win7 problem. Thanks This is real FRUSTRATING

Hi DJBigBang,

1. Have any USB or external drives worked on your computer? 2. What is the make and model of your computer?

As all the hardware devices have drivers associated similarly USB devices also have it. Sometimes proper drivers do not get detected after the initial installation so reinstallation of the drivers helps resolve the issues.

You may check after uninstalling and reinstalling the USB drivers if you are able to connect. You may disconnect all USB devices and then perform the following steps:

1. ClickStart, and then click Control Panel.

2. ClickSystem and Maintenance, click System, and then clickDevice Manager.

Note If Control Panel is in Classic View, double-clickSystem, and then click Device Manager.

If you are prompted for an administrator password or for a confirmation, type the password, or clickAllow.

**3.**In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".

Check if at all there is an exclamation mark along the driver, it suggests issues with the driver installed.

4. Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".

Then, restart your computer and Windows 7 will reinstall all USB controllers automatically.

If you still face the same issue then you may check for the updated USB device drivers using windows update. Refer to the below link for assistance–

http://windows.microsoft.com/en-us/windows7/Update-a-driver-for-hardware-that-isnt-working-properly

If the issue sill persists I would request you to check for chipset driver updates which you can get at the manufacturer website. The chipset drivers normally incorporate USB controller drivers as well.

Hope this helps.

Thanks,

Hello DJBigBang,

There is an old Windows XP KB article that was recently updated with multiple steps to resolve these types of issues. The KB covers Windows XP, Windows Vista and Windows 7 with step by step methods. See if this helps.

Sorry I Took So Long ... After not wanting to reload Windows and start all over I had to anyway. I just got this box back up and running after one of my 2Gig memory mods took a dump and took out my hard drive. Recovery from install disk would not even work.I did separate the RAID and used only 1 drive to reload for now. I will pull data off the other (I'm still trying to get it to boot) and reRAID later. But That is all another problem.As for this one ,I did unplug the KVM but that did not work. The problem existed before the KVM with just a plain old USB mouse and keyboard attached. I did not get to try the clean boot or corrupted profile ( only 1 profile on here) as I was reading email one day and WAM Dead Box (didn't even have video). So now, things are up and running again and all is well with the USBs, KVM and all. I am bummed out I didn't get to find out what was wrong but I hope it doesn't happen again. Thank You Both for your help. I did learn a few things so it was not all a wast of time.

Thanks Again

Hi DJBigBang,

Thank you for your post.

Are you using any USB hub?

Are these flash drives with SD cards in them, or just a flash drive with no removable memory cards?

I suggest unplugging the KVM switch and plugging in the USB flash drive.

If that doesn't work, you can perform a clean boot to check for software conflicts that may be preventing the device from installing correctly.

http://support.microsoft.com/kb/929135

You can also plug the flash drive in to the computer, then restart the computer in Safe Mode. Navigate to the Device Manager and check for duplicate entries for the flash drive.

When a device is hot swapable, such as the devices your having trouble with, a formerly installed driver may prevent the device from installing correctly a second time.

However it may only show up in Safe Mode with the device installed.

If that doesn't work, I suggest testing for a corrupt profile:
