I want to mine two different coins (different workers on the same pool) at the same time.
I am running 8 MLDs on one Pi.
I have 4 MLDs running each on 2 hubs(which I intend to extend if I get this working).

For this reason I power down one hub and start BFG miner with the first coin I want to mine. It finds the 4 MLDs and starts hashing.
Then I power up the second hub of MLDs and run a second instance of BFG miner with the other coin. It finds the other 4 MLDs and starts mining.

However after a short time the speed of first instance drops down slowly (a couple of minutes) to 1Mh/s per MLD and lower. I shut down this instance and restart it and it is back to 3-4Mh/s per MLD but then the other instance starts to slow down and goes below 1Mh/s.
I can alway repeat this back and forth, the instance that was running before will always end up runnning slow.

I don't see any hardware errors (600 clock) or any other unusual activity.

Anybody have a fix for this or another way to mine two (or more) different coins on one system?

this has been coverred several times, stop switching the hubs on and off and create 2 different launch scripts.

Can someone give me steps how to set 2 MLD sticks mining verge and the rest mining Litecoin?

create 2 separate configs or launch scripts and specify which devices to use with:

-S MLD:/dev/ttyUSB0 -S MLD:/dev/ttyUSB1 ... and so on

make sure to remove the -S all

if you're on linux here's a scipt to find out the correct device numbers to use

Code:

#!/bin/bash

for sysdevpath in $(find /sys/bus/usb/devices/usb*/ -name dev); do
   (
   syspath="${sysdevpath%/dev}"
   devname="$(udevadm info -q name -p $syspath)"
   [[ "$devname" == "bus/"* ]] && continue
   eval "$(udevadm info -q property --export -p $syspath)"
   [[ -z "$ID_SERIAL" ]] && continue
   echo "/dev/$devname - $ID_SERIAL"
   )
done

edit: Im running 10 now on a raspi2 through a hub been goig about 12 hours still at 4.3mh per mld

Thanks I got it now.
