more instrutions for the clueless would be nice I had a problem with bfgminer-5.4.2-win64 with it marking 2 of my Eruptors as Dead this morning I came to the conclution that the Serial Driver might be the cause So I installed https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers Win64 driver for Win10 I have version 1709 is this the problem Is my version too old??? I reloaded the Win10 Genaric and it works now but I still get a COM5 Error not enough Admin privlages which is BS I own the hardware.I niticed they are all set to 9600BAUD is this another error communication speed should be much higher right I did try setting it as high as my 3D printer communication rates this is when the driver crashed and I had to reinstill.... so Do you leve this com rate at 9600Baud???
