I bought a microsoft wireless arc for my a500. When i plug or unplug the usb dongle the tablet bugs out a bit, but after a second its ok. The keyboard doesn't work though.The volume buttons work for some odd reason but nothing else. Tech support argued with me that it wasn't their problem before telling me to call back monday to friday for t2 support. I was hoping someone here could help me before i return the keyboard. What are the requirements for keyboards to work, and are there drivers i can get? The arc keyboard doesn't come with drivers and works plug and play on pc. Also any recommendations for keyboards? I want to use the tablet to take notes in university instead of my laptop.
