I bought 2 x 2Pac usb miners. I got cgminer setup, but for some reason when I run cgminer only 1 of the 2pac's will run. Using cgminer -n I can see both devices, but when looking at USB management menu within cgminer it only show's 1. How can I enable both 2pac's to mine at once?
Edit:
I just tried changing the USB device used with the --usb 2:11 argument in my batch file. It says device not found. Why is it detecting both devices with the -n command but when running cgminer.exe it only detects one device, not both?
Thanks!
How are you powering both devices?

How are you powering both devices? on a USB hub

How are you powering both devices? This time I started it up and the other 2pac started working. So I moved one of them to a different USB connection and now both are being used. THis is annoying because now I wont be able to cool both of them now that they are in different spots and not on the same hub. Thought this hub could have taken both of them .... Thanks for your help.

You need more power. Find that hub's AC adapter, or get another good powered hub. Without the adapter, your current hub is splitting 500ma between all its ports.

Howdy,
I just went through the install guide for a rasPi (3) on the bitshopper site which is actually the same as in post 1 of this thread.
When I use the cgminer -n command I see the usb devices counter change when I insert the stick or not.
But it doesn't detect it as a 2Pac device.
Any idea what could cause this?

you may have to run it with ./ like you do with the autogen.sh script, ./cgminer
I went through the pages and found the above quote which solved my problem. without the ./ it apparently used the previously build cgminer altho I was in the right folder. now I have 1 of the 3 that seems to be working. the other 2 are stuck at 0/Hs even after I enabled them.

hello,
my sticks run default on 100MHz.
If I want to turn it up to let's say 150MHz do I need to tweak that tiny potentio meter?
And in which direction?
Can this be done when running or better to turn it off?
Does cgminer list the voltage somewhere? or do I really need to meassure it with a multimeter and compare it to that table on page 2 or 3?
Edit:
I seem to meassure 0.64V over both 'blocks' shown in that meassurement picture on page 2.
this value doesn't seem to reflect the 1.xx volts I see in the vcore voltage table?

It's one half the value shown. Each chip gets half the total voltage.
Frequency is a command-line argument, so you have to close cgminer, change the startup command and re-run it.
Most people don't really need to measure the voltage directly if you're only making a relatively small change to the frequency. Just keep a watch on your HW, and if it starts to go up, you need to turn the voltage up a bit. Righty-tighty, which is to say a clockwise rotation will increase the voltage.

I changed the frequency to 150 and then to 200 without touching the pot.
it seems to be quite stable with a laptop cpu/gpu fan on top of it to keep it cool (was very hot after a minute)
not sure if I can push it further as my adapter is only 2A.
if I interpret the chart right then it's 0.64*2=1.28 which equals (inbetween) the first and second line.
so 225 would be 1.95A and the max I can go with this adapter with a possible small voltage increase?

I tried with small increases so from 0.64 > 0.68 > 0.70
but it wouldn't mine at 225MHz and in some case not even at 200MHz. it's like the stick froze and the voltage also dropped to 0.16.
so I went back to 0.65V and 212.5MHz
and this is what I'm getting now which is ideal I guess?

If everything's working correctly, you should be seeing WU of about 1.53 per MHz.
gvb, your HW is very high so the voltage is probably too low. But it sounds like your USB available power is keeping you from being able to turn it up further. At 212.5MHz you should see 23GH and WU around 325 but I think your error rate is keeping that from happening.

indeed Sidehack,
I think my 2A phone charger power supply ain't stable enough but it's hard to find powered hubs in Belgium that deliver full power to each port and not the standard 0.5A.
I went back to 150MHz as I figured out this night that it stopped mining again after a while and I could not get it working again at 200, 180 either as it stopped after seconds/minutes again.
Now it worked fine through the night at 150.
this is my current stats
0: BSD 10015542: BM1384:2 150.00MHz HW:0 | 21.28G / 16.36Gh/s WU:228.5/m
Thanks for adding the leds, it's not only cool looking but it notifies me when something is wrong if it doesn't flash after a few seconds.

this one seems to be good for a bunch of 2Pacs. https://www.eyeboot.com/sipolar-10-port-usb-hub.htmlbut shipping to europe + import taxes (€30+, based on item price + price of shipping) makes it go beyond $100 for me.
