basic troubleshooting
1. if the tablet has a led light on it make sure its lit when plugged into the usb port of the system ,
2. see if after you've unplugged and replugged the usb cord in to the system that the system responds popups should occur saying something about adding new hardware or something ,
3. if possible try the tablet at a different computer dont download a free ware app or just install a trial of something from adobe

this will tell you if its the system or the software or the tablet thats the cause of the problems.. do see about downloading and installing the most recent driver for your device straight from wacom.com under support or drivers and support

look up Open Source, i.e gimpshop or paint tool sai on google ,i.e pressure sensitive open source art programs

Se trata de utilizar la herramienta de traductor Google. Para la compra de una tableta Wacom, considere su conjunto de habilidades y capacidad, y donde va a ir con él y considerar el presupuesto en el peso, así me las arreglé para ser extremadamente afortunado y encontró una tableta cerca del nivel del pro disponible para el 80 $ USD era el Intuos 3 hace aproximadamente un año. He encontrado la mía a través de craigslist sin embargo la caza a través de Ebay / Craigslist / Facebook - compra / venta / comercio grupos de su área pueden también existir. siempre las críticas, siempre conocer gente en lugares públicos w / cámaras, trae algo para probarlo o enciende y se puede utilizar (se tarda un minuto para conectar a un ordenador y para que lo reconozca para las funciones básicas). considerar también el tamaño, el área de la tableta más, mejor para ciertos tipos de trabajo y las pequeñas para más portabilidad.
=====================================
This is using the google translate tool. For purchasing a Wacom Tablet , consider your skill set and ability , and where you plan to go with it and consider the budget in the weight as well, i managed to be extremely lucky and found a near pro level tablet available for 80$ USD it was the Intuos 3 about a year ago. i found mine via craigslist however hunting via Ebay/Craigslist/Facebook - buy/sell/trade groups for your area may also exist. always read reviews , always meet people in public places w/ cameras , bring something to test it powers up and or can be used (it takes a minute to hook to a computer and for it to recognize it for basic functions) . consider too the size , the more tablet area the better for certain kinds of work and smaller for more portability.
