Hi all -
Thought it would be fun to thow my old Antminer U1s and U2s against a bitcoin -testnet.
Plugged the Antminers into a usb hub, and plugged those into a Gentoo linux distribution, they should up just fine and now I have (7) ttyUSB[0-6] /dev entries - a good sign.
Starting Bfgminer 5.5.0 with the command line:
bfgminer -D -S bitmain:all -o $POOL -u $WORKER -p x
The screen clears and I get:
[2018-07-12 11:57:00] Waiting for devices; press 'M+' to add, or 'Q' to quit
After a minute or two the process allows me to do the M+ but does not find any devices, even if I use the full /dev/ttyUSBx format.
Any hints? Use to run bfgminer a lot back in 2014, so I suspect I'm just doing something stupid, like using the wrong -S argument for antminer U1s.
My portage USE flags contain "... sha256d bitmain". Also:
Dev ~ # bfgminer -V
bfgminer 5.5.0
Lowlevel: usb vcom
Drivers: bitmain
Algorithms: SHA256d
Options: ncursesw6
Update: Dug through the code a bit and discovered "bitmain" apparently is for S1-S5 only. Rebuilt using the "icarus" instead of "bitmain" USE flag and now see:
Dev ~ # bfgminer -V
bfgminer 5.5.0
Lowlevel: usb vcom
Drivers: antminer cairnsmore compac erupter icarus
Algorithms: SHA256d
Options: ncursesw6
Of course, the startup script was modified to use: antminer instead of bfgminer.
bfgminer -S antminer:auto -o $POOL -u $WORKER -p x
Noticed when I tried M+ adding miners a VERY brief "you don't have access" type message poped up, so I tried as Root and vola! it found the devices.
Final note: at least for antminers, it should be "-S antminer:all" not "-S antminer:auto".
Is there a way to run bfgminer on a regular user instead of as root?
