Hi!

I have received my U3 yesterday.

Unfortunatly the U3 will not work.

1. Plug in Power
2. Plug in USB
3. Device is recognized and installs CP2102 Driver

Starting cgminer --benchmark ( Ver. 0.4.9.1 ) No Device found
Starting cgminer --benchmark ( Ver. 0.4.6.1 from bitmain HP) No Device found

Replacing U3 with a R-Box or New RBox and there are no problems, cgminer is hashing

Is my Bitmain U3 DOA?

Follow the instructions /vp1Yad]here, you haven't Zadig'ed yet.

I think nobody has read my post carefully.

Rockminer R-Box / New-RBox and a Antminer U2 are using the same driver and are running without problems.

1. Power up Antminer U3
2. Connecting USB to Antminer U3
3. CP2102 USB to .... show up in Device-Manager
4. starting cgminer 0.4.9.1 with --benchmark parameter
5. No Device detected / Waiting for USB hotplug device or press q to quit / Pool 0 not .....
6. waiting 3 minutes > nothing
7. Plug Rockminer New R-Box into USB and after a few seconds the New R-Box will beginn to hash

Antminer U3 DOA or what is my mistake?

THX!

I don't think you read our responses carefully. Step 3.5: Use Zadig to change USB driver to WinUSB driver.
