Have you tried using it on a different computer? it might be just an error.
Try restarting your PC and then try it?
maybe you need to redownload the driver files. they couldve been damaged
Go to control panel>administrative tools>computer management>device manager
In device manager, expand the "universal serial bus controllers" tree, and delete things from the bottom first, one by one, going upwards. Root hubs and then host controllers. Reboot, and windows will reinstall fresh copies from its driver cache.
Tried another USB port..?
I've got this drawing tablet that works in one of the usb ports on my laptop, but not another.
Try switching it around.

Dr. Evil,
Does Windows give any errors in the device manager, and what version of Windows are ya using?
Is it working on other ports, or is just that device? If you have another device, you can try that to see if the ports that are possible damaged, or something along those lines. Just need a little more info, that's all!
