If you're using the original power supply it will melt! Be warned... Mine took almost 30 hours before it finally melted...

At the moment I'm running with a normal raspbian image where I installed cgminer. Isn't hard to achieve. You only need enough juice Wink

TOO RIGHT!!!!

WARNING MY PSU THAT CAME WITH THE U3 MELTED WITHIN A DAY OF RUNNING WITH A VOLTAGE SETTING OF 0800 ( SO BE WARNED IF RUN ABOVE 0795 FOR VOLTAGE THEY MAY MELT AND / OR CATCH FIRE!)[/color][/color]

mine started to sizzle and melt after 16 hours at the 0800 voltage setting.
I strongly suggest that no one use a voltage setting higher than 0795 with the stock PSU
I ran that one for 24 hours with no problem. If anyone runs into a problem at that setting please let us know.

EDIT: Well I guess it doesn't matter if you turn down the voltage a bit from 0800, my second PSU went out running at a voltage of 0795 after a day and a half or so. This one went out spectacularly, sounded like something from a cheap movie, I have never heard an electrical noise that loud before (while it did melt part of the case for the PSU I unplugged it before there was any actual fire).
I don''t know if lesser voltages even are safe with these, it may just take longer for them to go out. At this point, for safety's sake, I think it is prudent to simply assume any PSU that came with a U3 is defective and should not be used.
