GOOGLE the model and find its specs, you didn't list the USB drives model so i can't really help with that. If you are running a ubuntu it lets you see in the device properties. In windows 7 if your device is not 2.0 and you use it, it will tell you that it is not 2.0. but if you get no notifications in windows 7 then it is almost 99% sure a 2.0 USB drive.
if i had the model i would have google it myself
but it's a usb disc on key that i got as a gift from a company. there is nothing on it but the company logo... it's some kind of advertising. a free disc on key with their logo.
anyway i need to know if it's usb2
