I have an A3 phone from Thailand, when I connect it to my PC running Windows it prompts me to install the driver to make it work properly. However, when I use my Ubuntu 10.10 there is an error detecting the device but I'm able to charge it. Is there a way I can make it work with Ubuntu?
Usually you have to enable the USB connection from the handset, too. Pull down the notification bar at the top of the screen, and switch the USB connection on. You don't need any drivers for this with Ubuntu, USB already works fine.
There's also an Android Stack Exchange site (like this one) over here.
