I am a teacher that is trying to use a set of 10 Arduino UNOs with my class. I have installed the IDE on the PC's we'll be using (which run Windows XP). The trouble I have been having is with the drivers for the Arduinos. The first time I connect an Arduino I'm told I need to install the driver which I do and everything is fine - as long as I use exactly the same Arduino. If I connect a different Arduino UNO (Rev. 3 just like the first one) to the PC I have to go through installing the driver again.
Now I'm in a situation where I have to label the 10 Arduinos and use a different one when I install the dirver on each 10 PC's and from then on each PC can only connect to the one specific Arduino I used when installing the driver.
What's going on and is there any way to do the driver installation so that it will work with any UNO?
