So I spent a good chunk of time getting BT3 to boot up correctly on my Acer Aspire One from a USB drive with changes. That is working well. I must have been in and out of BT3 from various USB drives about 15 times today. Last thing I know I run "macchanger --mac 00:11:22:33:44:55 ath0" and the computer locks up. So I do a hard reset and now my built in mouse pad has quit working. A USB mouse works though. Does anyone have a clue how I can reload the mouse pad and/or associated drivers?
