Addressed in 99c483c - thanks

I seem to now have a new error. One possibility I'm guessing is it's matching by device name/type and I have to identical miners hooked up to my computer.
System.InvalidOperationException: Sequence contains more than one matching element

Can you send me the XML files in ~/.config/MultiMiner please?

from multiminer.

Can you also show me the output of:

bfgminer -S erupter:all -d?

from multiminer.

Hey Nate,

I am at work at the moment.
I'll send it as soon as I get back home

Here's bfgminer output. Note I'm currently running another instance of bfgminer in interm, so that's why it says in use.

Here is a link to the zip with the XML files. I edited the Coin settings to remove passwords.

I need the output without any devices being in-use please.

from multiminer.

Also note that the worker name and password cannot actually be used to login to anything.

from multiminer.

From looking at the XML file, it looks like bfgminer is going to report two different USB devices with duplicate (supposedly) unique serial numbers.

from multiminer.

Here's the output running alone.

Yup that is the issue. Both of your devices are reporting the same serial number, even though these should be unique. Can you try this update:

from multiminer.

Now the main window comes up. The start button is greyed out for some reason, though.

from multiminer.

Can you show a screenshot? You'll need to configure coins and then select the devices, right-click and assign coins.

from multiminer.

I didn't see the coin assign was moved to right click. It's there now. A miner quibble is it seems to not show the second miner's hashrate.

I was actually just looking at that bug. I should have a fix for it soon.

from multiminer.

Alright, good to hear. The original bug is effectively squashed.

from multiminer.

Can you please re-download that zip file and see if that fixes the display issue?

from multiminer.

Yep, that's good now too.

Glad to hear it - thanks again! d82d563
