My Laptop has 3 USB Ports.

No other Miner connected!!!
I have tried other Computers!!!  ( Driver shows up, cgminer: no devices detected )
( i'm wiriting this just because you think i'm stupid and do all wrong )

Even on Ports where the U3 never was connected zdiag 2.1.1 shows:

cp2102 USB to ....

Driver WinUSB (v6.1.7600.16385) --> Driver WinUSB (v6.1.7600.16385)

                                                   Reinstall Driver

I HAVE REINSTALLED THE DRIVER!!!

cgminer 4.9.1 --benchmark still No devices detected!


EAT THIS!
