Title: Antminer U2 setup problems Post by: jburke4 on April 06, 2015, 11:11:37 PM 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 Title: Re: Antminer U2 setup problems Post by: Mikestang on April 07, 2015, 12:06:42 AM You have to zadig the U2 with cgminer.

Cgminer is more updated but BFG runs for my Scrypt small miners fine Title: Re: Antminer U2 setup problems Post by: jekecoin on April 07, 2015, 12:18:13 PM Install CP210x USB driver from http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx (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 Fun :) |
