Install CP210x USB driver from http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

Try BFGminer

Code:

bfgminer.exe -o MY_POOL_URL:PORT -u MY_WORKER_NAME -p WORKER_PASSWORD -S antminer:all --set-device antminer:clock=x0781

For overclocking:

Code:

For 1.6 GH/s, use 0781 (this is the default)
For 1.8 GH/s, use 0881
For 2.0 GH/s, use 0981
For 2.2 GH/s, use 0A81

You can try BFGminer as well.
Cgminer is more updated but BFG runs for my Scrypt small miners fine

I'm trying to setup an Antminer U2 with multiplool but can't seem to get it to work.

I'm using the command line:

cgminer.exe -o stratum+tcp://us-east.multipool.us:9999 -u jburke4.1 -p x

With cgminer I get "No devices detected" I see the device listed in both device manager and in Devices and Printers as Silicon Labs CP210x USB to UART Bridge (Com4) It does eventually seem to find the device but It does not appear to be doing anything productive. I keep getting in an endless loop:

Pool 0 difficulty changed to 256

I have tried every server they have listed and keep getting the endless difficulty changed loop. I tried the antminer pool as well withthe exact same issue.

Also once working should I adjust the Bits per second in the hardware properties? It's currently set at 9600.

Windows 8.1
cgminer 4.6.1 x64
