USB devise not recognized in My Computer

You may need to reassign them to a new drive letter. I have had this happen several times in the past. Open disk management in Admin tools, and reassign the drive letter.

What happens is the devices are assigned the next drive letter.

In XP is you have drives a, c, d, f the device would normally attach itself to E and the next device will attach itself to F which is already assigned to something else.

Go into the Control Panel, Administrative Tools, Computer Management. In Computer management select Disk Management.

You should see your need USB device in there, where you can assign it to another unused drive letter. You right click the mouse to get the menu to change the drive letter.

Then you should be able to see the JumpDrive in Windows Explorer or My Computer.

I was having a similar problem and what this is what I found out. The usb connections in the front of most PC's are only 1.0 compatible. You may need to get a USB hub to extend your capabilities if you your device is 2.0. If you buy a powered hub, get one with its own power source. Also as a word of caution, disconnect or shut down any USB devices that you are not using (its possible to overload your system). If possible use the parrallel ports for mouse and keyboard, this will help because every system has a limit to the number of USB devices you can hook up. Lastly, don't forget to close and re open your Windows file manager after plugging in your USB device. Good luck!

take out the usb thing and put it back in or restart your computer and doit agin or install the disk if it came with one
