TESTING YOUR TABLET

tablet directly into the system USB port located on your computer.  Temporarily eliminate any 
external hubs in use until you determine that the system recognizes the tablet and that it is 
functional.  When the tablet is working properly, it is usually okay to then move the tablet to a USB 
hub.
