Picked up an A500 today after carefully reading through the documentation on Acer's support site as well as the user manual for mentions of USB keyboard support. It says implicitly that there IS support for USB keyboards (just not USB mice yet). However...I can't get a single USB keyboard to work (I've tried 3). Anyone tried this yet and gotten it working? I know the USB slot is working ok, because it reads a thumb drive just fine. Thanks!
