I purchased an ADATA 16 GB USB 3.0 Flash Drive for the purpose of running Ubuntu and I used "UNetbootin" to do so (Ubuntu 12.04 Live). Whenever I boot from the flash everything seems to go fine, when I select Install Ubuntu it loads the Installation with no issues but once I get in my keyboard doesn't function at all. I can move the mouse cursor around but I can't left click on anything to continue on with the Installation. I am a total newb at this stuff and any insight would be extremely appreciated.

Thank you very much!
