Okay, so are you saying there is a way to adjust the global wait factor? Or that it's not going to work on OSX at all? I'm running 18 USB devices on that machine no problem otherwise (yes i tested this without them hooked up). I did have USB issue on Intel Machines with too many hard drives connected, on a couple of machines, but i've never had any issue on Apple Silicon. I know you said OSX itself, but not sure if that would be any different.

Thanks, i've asked in that thread. Hopefully i've just done something stupid and this is an easy fix 

Hello, newb here... Having a pain getting my R909 to work properly on the same system as 4 Compac Fs. It was recommended i ask in here to see if anyone has an idea of what's going on instead of in my own post.

Command i'm running: /opt/homebrew/Cellar/cgminer/4.12.1/bin/cgminer -o stratum+tcp://solo.ckpool.org:3333 -u "my bitcoin address" -p x --gekko-r909-freq 500 --gekko-compacf-freq 545 --gekko-start-freq 300 --gekko-tune-up 85

I've tried running the R909 out of a free port on the Gekko Science hub, tried running both through a USB 2 hub out of the same USB port, tried running through different USB ports on the same computer, all no gos. It crashes resets and tries again. The WU: (Work uptime?) for the 909 gets stuck between 50 and 65% and never gets higher once the frequency is reached.

I should say the R909 works totally fine on a different computer by itself as a separate worker, or on the first computer without the Compac Fs running. I've tried running all devices on both an M1 Mac Mini and an iMac Pro, and on both the WU stays low for the 909, then resets.

Only other thing i can think of is i'm running the kanoi/cgminer fork that installs through homebrew. It is at version 4.12.1.

I'm new enough that this is all out of my depth. Any suggestions for what i should be doing here would be much appreciated.

Thanks!

Well i'm only running 4 Compac Fs and one 909, and it's connecting to an M1 Mac Mini, so i'm doubting that's the problem. Unless people have had issues with M1 Mac Minis before.

What i'm reading seems to imply power might be the issue. That seems weird, but worth a try plugging into different sources. It was one last thing i hadn't tried.

So the data bandwidth is possibly the issue? I've seen people mention running like 15 Compac Fs at the same time through a Pi. Okay, i'll go through the thread. Thanks for the link!

Newb here to this forum. Recently got into "lottery mining". I have 4 of the Compac F USB miners running using the Gekko Science hub. That all works fine. Still have some tuning to do for getting the different sticks to run at different frequencies based on what that hub puts out, but that's a different question.

My issue is i also just bought an R909 Terminus miner and i'm having a pain of a time getting the Compac Fs and the R909 running at the same time on the same computer. If i run either separately, works like a charm. Turn on the other, USB failures.

I've tried running the R909 out of a free port on the Gekko Science hub, tried running both through a USB 2 hub out of the same USB port, tried running through different USB ports on the same computer, all no gos.

Another suggestion i had given to me by the guys at Bitcoin Merch was to run the 909 through a different terminal window. This part i've probably not done well. Basically ghosted the 909 in the one window and then started another where the 909 ran until USB errors happened on both sides and then confusion ensues as both terminal windows try to load devices randomly.

Can you point me to proper cgminer terminal commands to exclude specific miners per terminal instance, or if anyone knows what the trick is that i'm not doing right to get this combo to work?

I'm currently running the 909 on a different computer for now, but it's not an ideal setup. I'd like it all running on the same machine.

If it matters i'm running it all on an M1 Mac Mini. No resource issues on that end.

Thanks for any help!
