Help guys, I have 2 U3 antminer, 1 I bought from china, the other I got in my country. The chinese one came with original power supply conected to pc and tried on raspeberry pi 2, both with no success. Chinese from start didn't work, got steady light at led and tf1 (leds), sometimes rf1 blinks once and stops, cgminer doesn't detect u3, but windows does I followed instructions and used au3-freq 225 au3-volt 750, as described as default for the miner. Chinese seller did extensive test over teamview an decided to send a new board.
It took 60days for the u3 to come, so more 60days with a new paper weigth, I got angry just tinking about it and bought another U3 in my country to mine while the board doesn't arive.
The new u3was the same model, I did the same config, worked for 1 day and stopped working. Now I only get a steady light at led, and rf1 blinks once no other.
Can any one help me understand or maybe fix, if its fixable?

Are you using same power supply? Do the two share any part's. To have 2 dud's from different sources is unlikely. I'm guessing there is a shared issue.
And I could be wrong but look at what the two share. With windows Zadig can sometimes give problems. So might look into driver. With RPI though I would try more with it. What issues did you run into with RPI?
The one that i got from china, arrived dead with original power supply, the one that I bought in my country came with a switch power supply.
Before the u3 from my country stop working, i tried tried both power supllies on it, both worked perfectly (so that would rule out power supply problem).
They never shared a part, only power supply and usb cable, so i could rule out bought as a faulty part. They didn't use the same power supply simultaneously. It couldn't be zadig, since i always used the raspeberry pi 2 too mine. About the led light i tried with different cables, different systems (pi and pc), different usb cables, different usb ports, different power supplies.
thanks for help!!
