Does anyone here run the Compac F on a Sipolar USB hub? I am just trying to get a handle on what kind of hash rate is achievable running a single miner on this hub. So far the max average I've been able to achieve is about 180 gh/s at 325 mhs. That's fine if it's all that's possible - I just want to understand if there's any success to be had by playing about with the voltage screw & frequency settings.
I understand that it's not the recommended hub, but they're impossible to get hold of atm. Thanks!

Hi all,
with the difficulty to buy a good usb mining hub , I finally worked on my own design
https://i.ibb.co/Nj56pdq/usb-mining-hub.png
main features :
pci-e power connector 12V
3 power linear regulator 5A each
3 variable resistor to adjust 5V output
Atmega328 with LCD to display data like power of each usb port like usb key power meter
4 ports USB and 2 with just power for raspberry or fan
ports 1 and 2 share same 5V with usb hub data
port 3 share same 5V with one usb hub data and port4 with just power (fan, raspberry)
same configuration for port 5 and 6
I plan to add connector for fan because a thermal dissipator is need for the 3 linear regulator and a sensor to manage temperature
It works since one week without any issue
https://i.ibb.co/Kz3t75m/cgminer.png
Now I need program ATMega to display data and my prototype will be finish

Looks great, I am sure there would be many of us looking to purchase something like this. I am also waiting to get a GekkoScience hub and check everyday to see if I can purchase one.

Yeah I never use a config file, just a command line or shell script that's easy to edit because it's basically one command line.
got it.. thanks.
finally, thanks guys.. every single issue i had has been resolved including the usb bandwidth thing even tho one of them is still playing catch up... seems the issue was related to windows...
Im currently running rasp OS on one of my pcs and so far so good...
just waiting for the usb amp meter i ordered on amazon to set all the sticks at a set power rating...

Yeah I never use a config file, just a command line or shell script that's easy to edit because it's basically one command line.
what of the config file ? i will like to input my settings in it ... how do i create / locate it ..? looked through the cgminer directory looking for gekko.config i imagine but didnot find one ..
The extension for the config file is .conf.
The conf file is a pain in the a--. I like just using the command line so that I can easily make changes when I want to try something different.
But each to their own. Just don't forget you started using the stupid thing because it overrides your command line when you try using it.
Oh yeah that old guy. Error as old as cgminer running USB devices. From the Compac/2Pac support thread:
Q. How to get past "USB init, open device failed" ... "you don't have privilege to access" error.
You'll want to cd into the correct cgminer folder, but that is probably obvious. Either that, or run cgminer as root.

Q. How to get past "USB init, open device failed" ... "you don't have privilege to access" error.

That solved the issue, thanks a bunch. what of the config file ? i will like to input my settings in it ... how do i create / locate it ..? looked through the cgminer directory looking for gekko.config i imagine but didnot find one ..

There's a link in the first post, to a post hanging out on Page 3, with all the instructions you could want.
Thanks. I found the post & was able to setup cgminer just a couple more things...
1. im not yet able to generate the gekko.config file... still not sure how..
2. when i run the cgminer, it showing GSH errors , cant detect miner which i believe should have been GSF hence looking for the wrong hardware.. how can this be corrected ?
Some indication of the output of the screen in [ code ] tags would help, or a screenshot.
Certainly .. see below.

I need help, can anyone share links that can guide through the process for compiling cgminer on rasp OS..
Anyone knows a good Rasp Pi source ? cant find stock online.. Pi 4B 8Gb..
All the good retailers have no stock, one says due in around 14th March here in the UK.

found this on amazon: X-DRAGON Dual USB Digital Power Meter Tester
is that it ?
Yeah, look for 'USB amp meters', but it sounds good. I personally prefer the straight ones, where the miner is plugged in a straight line with the USB ports. That way it fits better onto the hub. But any type should work.is that it ?
Thanks, I found the type you refer to, in form of a flash drive.

You also need to have a USB power draw thing (I don't remember the technical name but it plugs into the USB port and the stick plugs into that) for testing and adjusting voltage because you can end up with way to much power even at 500MHz if you have too much amp wise if you adjust too much on it. After I finish each stick I just move the next stick onto it. So you only need 1 of them and they are less than $20 on Amazon.
Nice. will look for that. do you have a link to share on amazon for it ?

I think you are going to continue to have problems on a Windows based machine. Each stick upon receiving them I did run myself on my personal desktop (at the time a AMD 3950x on a Gigabyte Aorus MB, but I used a USB hub that could provide 2.5A so even at 500MHz it would get angry at points). The PI is a cheap very easy to setup solution and you can just set the sticks up with some kind of cooling solution and forget about them really. I monitor everything through the default miner.php included in cgminer.
Would Prolly go that route, hopefully i get sorted out. thanks. about the miner.php, how do you access it ?
