[android-developers] Re: Why ADB and DDMS cannot recognize my phone in Ubuntu?

Make sure that you have USB debugging enabled on your phone:

Settings -> Applications -> Development -> USB Debugging

Then use /usr/sbin/lsusb to see the VID and PID of your device

I don't know the VID and PID of the Acer Liquid.
But be sure that what you find with lsusb matches your UDEV rules.
