i have the same one and didn't have that issue. I heard you can have problems if you install the program after you plug in the usb cable. did you do that? unfortunately, this was my first experience with this type of thing.
I just used the drivers on the little cd. i would try uninstalling all the software and programs, rebooting, and reinstalling. might have to clean up the registry first also. that's all i can think of and i'm betting you already tried all that.
are you in windows xp?
