![]() ![]() I did try multiple different BEs, and all had the same result. I did read through the various readme files, but nothing pertinent jumped out at me. I also tried editing the config file to delete everything except my pool. I run cgminer with no command line options, just the config file. I've tried this with cgminer 3.4.1 and 3.4.2. (Once we get to the point where cgminer sees the BE, I'll ask the follow up about why this PC says it runs out of USB resources after about ten devices.)Įdit: Couple more bits of info. There's no error message from cgminer about missing drivers, or anything like that. There's no yellow ! sign in Device manager. If I plug a USB thumb drive or keyboard into the same slot as the BE, it works without issue. Tried a hub with a BE in it, same thing - no response from cgminer. Trying other slots, USB2, USB3, all elicited no response from cgminer. Unplugging and replugging the BE did nothing. It didn't give any error message indicating USB problems or anything like that.Ĭonfused, I saved the config file, exited, and ran cgminer-nogpu. It found my graphics card, but not the BE. It asked for my pool info, which I entered. If I unplug it and replug it, Windows doesn't give any error messages. Now the device appears properly in the Device Manager. I ran the Zadig tool and installed the WinUSB driver. Windows dutifully reported that the driver failed to load. Next, I plugged a single Block Erupter directly into USB slot on the case. Downloaded and unzipped Zadig and cgminer, but didn't run them yet. Ran Windows Update until it ran out of things to patch. Installed Windows 7 Ultimate, drivers for the motherboard and graphics, Microsoft Security Essentials, 7-Zip, and nothing else. When I got to my new place, I bought a new Core i7 4770K based PC with a Z87 chipset based motherboard, a 7970 graphics card, and all the other usual accoutrements. I recently moved, but I didn't take my computer with me. OK, I have a strange situation here, maybe y'all can help me make some sense of this. usb :1 means grab whatever the first USB mining device is, it can find, and only one device Of course you can change or add more to the -usb option if you also have other non ica devices. If you wish to handle each device independently, you need to run a cgminer for each device (and each will connect to all the pools individually)Ĭgminer-nogpu -o -u user.1 -p password -usb ICA:1Ĭgminer-nogpu -o -u user.2 -p password -usb ICA:1Ĭgminer-nogpu -o -u user.3 -p password -usb ICA:1Īnd each cgminer would only use 1 ICA device (ICA is the driver for AMU,ICA,BLT,LLT,CMR) Or it will assign all devices to all pools(/workers) in balance or loadbalance mode etcĬgminer-nogpu -o -u user.1 -p password -usb ica:1 -u user.2 -p password -usb ica:2 -u user.3 -p password -usb ica:3Ĭgminer will assign all devices to the first active pool(/worker) in failover mode (the default) its easier to see which stick is doing what Yes but all 13 erupters will use the same worker, cg and bfminer works well but i want to assign each erupter its own worker.
