I still can't figure this out. windows 2008 r2 x64, cgminer 2.4.2

I'm using a config file, I have 4 bfls

Using "scan-serial" : "\\\\.\\COM4",
finds only 1 bfl Sad

this does not work either
"scan-serial" : [ "bfl:COM3", "bfl:COM4", "bfl:COM5", "bfl:COM6" ],

Instead of scanning, why not just put in their ports? (e.g. using the -S switch when you start cgminer)

try looking in device manager to see where they are.

yes please i will do that, but HOW?

"scan-serial" : "COM3, COM4", etc does not work

That is interesting, I didn't know you could use scan-serial in the config file. I just tried using it as well, and it's only noticing one of the BFLs too.

oh could be a config file bug
how do i do it in the command line? i will try that

In the past, to get all of mine to work, I use a startup script (.bat file for you) with my command line options like this:

cgminer -Sdev/cu.usbserial-001013FA -Sdev/cu.usbserial-002013FA -Sdev/cu.usbserial-003013FA -Sdev/cu.usbserial-004013FA -Sdev/cu.usbserial-005013FA -Sdev/cu.usbserial-006013FA -Sdev/cu.usbserial-007413FA -Sdev/cu.usbserial-007513FA -Sdev/cu.usbserial-007613FA -Sdev/cu.usbserial-007713FA

I'm using cgminer 2.4.2 in osx, so yours in windows would probably look like:

cgminer -S COM4 -S COM5 -S COM6

I'll see if I can figure something out about using the conf file.

Yeah, thats what I was thinking. By repeating the same array value ("scan-serial") it might just be overwriting one value instead of multiple instances, so you end up with whatever that is set as (probably the last one).

Thanks but now its crashing when i use
start "CG Miner" cgminer.exe -c cgminer.conf -S COM3 -S COM4 -S COM5 -S COM6

this doesnt work at all
start "CG Miner" cgminer.exe -c cgminer.conf -S COM3,COM4,COM5,COM6

using one works perfect however
start "CG Miner" cgminer.exe -c cgminer.conf -S COM5

you need a -S for each:

-S COM4 -S COM5 -S COM6

I did
start "CG Miner" cgminer.exe -c cgminer.conf -S COM3 -S COM4 -S COM5 -S COM6

I'm running out of ideas. What are the ports that your BFLs are assigned to (via Device Manager)?

You could try using the whole port, like this:

-S \\.\COM3 -S \\.\COM4 -S \\.\COM5

You could try installing the drivers:

See if that helps.

-S \\.\COM3 -S \\.\COM4 -S \\.\COM5
crashes it https://imgur.com/WF6uH

Mine are 3,4,5,6

Is no one using multi bfl in windows? Sad

Everything I'm reading says that it should see them up to COM9, so for COM10 you'd need to use \\.\COM10 for anything above (i'm grasping at straws). If the drivers don't work, I don't know what else it could be.

Thanks for your help. They each work individually. I just cant get them all to run.

When I was trying to get all of mine to work together, I just called multiple instances of cgminer. It's ugly, for sure, but it worked till I could make some headway. Way less ugly than having them just sitting there.
