With --usb you can say how many devices to find or how many each driver should find
So for each cgminer
--usb BAS:1
would grab only one BAS device.
If you use
--usb :1
it would grab the first device of any USB mining devices that you have. (this also has the minor advantage that it stops polling for hot-plugged devices until the current device disconnects)
Kano, Thanks!!! This has been the best tip for running Block Eruptors. I was constantly loosing them one by one and then restarting cgminer. But when I added --usb :29 it finds all my BEs and then if one stops it finds it again and it reappears with a higher AMU number, but every time I look since I added than command I find all 29 running!!!
Is there a conf file syntax for this or command-line only? (I like to keep everything in one place.)
Does hotplug polling have much cost? Just curious.
Also, I rolled back to cgminer-nogpu.exe 2.5.1 and BFLs and BEs run fine. My GPU miners don't care 2.6.2 or whatever.
