Just got my TB and am trying to put the appropriate files on it from my mac. When I plug in the TB dongle an error of Low Power comes up asking me to either connect to power cord or other USB input. Tried on my macbook and desktop mac with same results. What can I do? Can I install the TB CFW w/ a different USB drive and then use the TB after? Also, when TB is plugged into PS3 nothing happens either. Multiman doesn't even show that a USB drive is plugged in.
