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: 18.104.22.168 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???
My reader will not read mine either. I use a usb key card reader. It used to read the regular old SD cards but the new HC card format wont work. This is due to UDF differences. You can try to reformat the card but then your camera or device may not recognize it anymore. good luck
If it is a desktop computer, try connecting to one of the rear USB ports. sometimes drives won't be recognized properly from a secondary USB or HUB. If it's a notebook go into control panel and see if you can find and delete unknown devices in hardware
then attach and see if it connects. XP should not need a driver install.
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.
