I am completely new to Bitcoin. I am trying to connect Slushpool using BFGminer, but its showing some USB device not detected? I am a newbie and don't know which device it needs. What should I do?

  • Are you trying to mine just with your plain computer? BFGminer is probably expecting you to use an ASIC, specialized hardware for mining.

The best gaming PCs gave up in 2013. Now you need ASIC hardware to mine. Even 1 TH/s (1000 GH/s) is not fast anymore - I wouldn't buy slower than that. The device bfgminer is looking for is an old and slow ASIC that connects to the USB port of your PC.

Modern miners are stand-alone machines which connect directly to your network, not to your PC. You don't need your PC or bfgminer for the mining. You use a browser on your PC to configure the miner, after that it mines on its own.
