I'm trying to get a wireless mouse and keyboard combo working with my Acer Iconia tab a500. Picked it up for cheap at Radio Shack. It's an iconcepts 62350NS keyboard mouse combo if that helps. Anyway, it came with a USB dongle, and my tablet has a full sized host USB port. Theoretically it should work, but I can't even get a pointer to show up. Is there some setting I need to change? Maybe desktop keyboards don't work? It was really cheap, so if it doesn't work, not a huge deal. My tab has android 3.2.1 on it.
