I have been running my Antminer U1 and U2's off my Windows install for a while and I decided to switch this ASIC-controlling laptop to Debian instead. I am currently running 3 Gridseeds off it (/dev/ttyACM0-2) and I am working on getting a GawFury to run as well. The same laptop ran everything under Win7 x86. (However not as smooth as i wished, the cgminer3.11 version for GawFury is horrible)
I've compiled bfgminer 3.10, 3.59 and 4.2.1 to try to run the Antminers. (They ran under 3.10 on Windows.) I've compiled bfgminer 4.2.1-DarkwindE (spelling?) to try and run the GawFury.
However, what is happening is that I can plug in at most 2 Antminers before I get problems. The GawFury wont detect properly no matter what i do with it. The system will add ttyUSB0 1 or 2 for it. I never get ttyUSB3 added to /dev for some reason, which i should because they all use the same SiLabs cp210x driver.
All *four* cp210x devices get detected as /dev/ttyUSB0-2. Does not matter what order i plug/unplug and confiruge them in. They all appear on running lsusb. I have tried to run these devices by specifying USB ID's ("usb" : "7:12,7:13....")
When plugging in Antminer #2 or #3, one of the other Antminers will disconnect after 1-2 secs and fail to reconnect, *OR* the device I insert will just give me 'failed to open /dev/ttyUSB2'. So its completely random which device will fail when i plug in additional antminers.
The GawFury refuses to do anything at all. I have tried to specify the device by 'zeus:/dev/ttyUSB0' and just '/dev/ttyUSB0'
I've tried recompiling cp210x. I've tried probing the drivers. I've tried to add my root account into dialup group.
Both the Fury and the one or two failing Antminers will emit a repeating series of 7 led flashes + ~3 seconds pause when they fail to detect properly.
I have no idea what to do next. How on earth do i get this cp210x stuff to work ? I did read some post somewhere on some forum what the driver was broken in the newest Linux kernel in Debian. But I can't get this confirmed anyhere. Hope someone can help! Thanks.
