USB Device Not Recognized error flashes on and off .
I touched my computer and got shocked. The USB drive registerrred an insertion and thinks there is hardware installed. I looked under the device manager and it says Unknown Device. The only way for me to turn it off is to disable the driver. When I uninstall it just comes back. Flashing and beeping. Is there a way to just Delete the device somehow?

Instead of disable, right-click and choose uninstall. Good old static electricity will destroy many an electronic - the official right way to touch the computer (which no one really does) is to run your hand across a wooden table or other hard surface (not the carpet, now) before touching the computer or monitor - or wear anti-static gloves. Usually not a huge issue, but you have joined the unlucky minority.

My Verbatim Sto N Go 8GB USB Flash Drive does not work in any port, in any computer. When I plug it in, the "Device is not recognized" error comes up. When I click on it, and the Unknown Device Properties comes up, the device status reads: "Currently, this hardware device is not connected to the computer. (Code 45)
To fix this problem, reconnect this hardware device to the computer."
The driver details read: Provider: Advanced Micro Devices File Version: 22.214.171.124 built by: WinDDK Digital Signer: Microsoft Windows Hardware Compatibility
This is the 2nd drive of this same brand that quit working within 6 months. I have MONTHS of work on files in this drive, and would hate to have to redo all that work! I was real careful after the first one went bad to use the eject button when removing it from my computer. But I am thinking the last time I clicked the eject button, it froze, so I just pulled it out without the message coming up. Hopefully there is someway to get the computer to recognize this drive again???
1 Connect your flash drive to your computer using an available USB port. If your flash drive is not recognized, you'll usually receive an error that says "USB Device Not Recognized."
2 Click "Start" > "Control Panel" and open the system configuration by double-clicking the "System" icon.
3 Navigate to the "Hardware" tab and click the "Device Manager" button to open the Device Manager.
4 Click the "+" next to "Disk Drives" and locate your USB flash drive. A question mark icon should be shown to the left of the label. Right-click the device name and select "Uninstall."
5 Open the "Action" menu at the top of the Device Manager and select "Scan for hardware changes." This will scan your PC for any new devices. Because you uninstalled the flash drive, it will be detected as a new device and the drivers will be reinstalled.
6 Click "Start" > "My Computer" and look for your flash drive. If this process was successful, your flash drive should now show up under My Computer as a storage disk.
Hope the above information will be helpful to you. Thanks.
You mentioned that you uninstalled the unknown device from the Device manager. If you uninstall it then connected your usb flash drive you will see an error again on your device manager. This means that the driver for your usb port is not properly installed.
To install it, visit dell website, look for the model of your machine and locate the driver, download it then install from your machine.
This solution worked for me when I got the USB device not recognized message: http://www.infobarrel.com/USB_Port_Repair It can be quite frustrating. I've heard that older computers are more likely to have the USB device not recognized message.
We can fix it -- and recover the data (provided it is recoverable -- which it generally is). If we don't get your data back, we ship the drive back to you and you pay nothing. We've been recovering data for over 16 years and are successful about 85% of the time.
