Bit of an experiment.

I have 2 x ASIC Miner Block Erupter 333Mh/s Rev. 3.00 plugged into powered USB ports.

I've downloaded and installed CP210x_Universal_Windows_Driver from https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers.

I see:

enter image description here

If I run bfgminer, I receive an error "no devices found. Press 'M' and '+' to add". I press M, then +, but no devices are detected.

Help appreciated.

This is the tutorial I was following.

Try following the ASIC instructions provided with BFGMiner

These will autodetect if supported by the device; otherwise, you need to use the '--scan-serial erupter:' option to tell BFGMiner what device to probe; if you know you have no other serial devices, or only ones that can tolerate garbage, you can use '--scan-serial erupter:all' to probe all serial ports. They communicate with the Icarus protocol, which has some additional options in README.FPGA

Try adding --scan-serial-erupter:all to the command for starting BFGMiner.

  • Do you know if BFGminer monitors the temperature of the devices?
