Why are you adding -sha256 its not necessary.

yes, i did.

i also tried:

This is how I run cgminer:

ideally, you measure the voltage with a multimeter, then follow the table in post #1.

how about this: return the voltage adjustment where it was, remove the whole folder (using rm -rf command; see the home dir for the name of it, could be vthoang or git or git/vthoang, I don't remember, and build the whole thing again very carefully (no mistakes).
Reboot once or twice with the problematic stick attached. I was also using Pixel, not sure which kernel since i used whatever default they had on pi website.

Are you running cgminer with ?  I'm running 3 pi's and that got them started

Yes, i also tried to adjust the voltage as mentioned in page 2 but without any luck. I turned to 1/8 clockwise, unplug and wait 2 secs and plug again. I also tried 1/4 turn, unplg and wait 2 secs and plug again.  Nothing has changed, problem still remains. ><


Pls advise and help.

If you bought from eyeboot, it's a green stick. Note that the board it's build on is green. The ones in Europe are made with a black board.

Have you tried adjusting the voltage a bit higher and replugging it?

1. I bought it from eyeboot. (bought two sticks);

2. pretty sure i am using the most updated VH's cgminer driver, because one of my 2pac usb stick is running well individually (and followed each steps to build, as well as tried to find solution from all old posts, no solution).  The problem stick is just couldn't be recognized individually and inactive (tried other ports).

3. Rasbperry Pi 3 with Raspbian Jessie with PIXEL (kernal 4.4)

how to check green or black stick?

Green stick or black stick? Who did you buy it from?

Make sure you're using the most updated version of VH's cgminer driver as detailed in the first post.

Depending on what Pi software you're using, you might need to move some files around to be executing the right cgminer build.

hi Biodom,

I did all the codes you have mentioned, but nothing has fixed. My 2pac usb miner is still inactive.
I have tried to plug the usb on different usb ports, but still not working. But it gets an error message below:
"get GekkoScience detect (1:12) failed to initialise (incorrect device?), resetting failed usb_init"

Pls advise how to solve the problem? Thanks.

^^^^Did you do what i told you to do in my post directly below your "post 488"?
Your second message contains no info on what you did, exactly.
I am not going on some dinky site to check your pic.
Post on imgur or other more reputable sharing site and link here as a pic.

sidehack checks each and every stick before sending out, so it is VERY unlikely that it is broken.

Dear All,

Refer to the Post #488, I am still having the problem.
Here I post the capture screens below for your reference. Pls advise and help.
My 2PAC usb is still not recognized by cgminer. (Running on Raspberr Pi 3)
I wonder if i've bought a defective one.

Thanks All.

There is no reason what-so-ever for the words AMU to show up in your question if you follow the instruction in the OP of this thread.
Toss out or set aside the cgminer binaries you have.  Re-read the first post.

Hello
I have installed a Raspberry Pi freshly and I also kept up the instructions (is very well written thank you). 
Unfortunately, the stick but not correctly recognized, I have only about 1Mh / s
Under "USB management -> List all know devices" I get the Miner correctly displayed
Bus 1 Device 19 ID: 10c4: ea60 bitshopperde 2Pac BM1384 Bitcoin Miner active
In the survey, however, only
0: AMU GS-10013: | 2.001G / 593.2Mh / s WU: 9.6 / m
The topic has already been done but unfortunately only with see above  
I do not know which I should still make
*** HELP ***

RPi3 will run at least one 2Pac @ 100MHz.  I ran one for a couple days with no issues.  Powered the pi with a 2.1A supply.

Two possiblities (init or power)
For init, follow post #1 (Q/A section);
heck, here is the code:

For power, try adding the following:

this is instead of default, which is 100, I believe.
I don't think that rasp pi 3 has enough power in USB connectors to run at default, but I could be wrong.
Most people use USB powered hubs like Superbpag (it is another $35, unfortunately).
Also, sometimes if above did not work or if it shows as a zombie, replug it "live".

Hi All,

I have bought the GekkoScience 2PAC usb miner, but it cannot be recognized by cgminer. It always showing as inactive. How to config cgminer to make it active? Pls advise. Thanks.

I am running it on Raspberry Pi 3.

Thanks.

Read the first post.

I would like to make some some newbie questions:
I just got USB-Stick Miner bitshopper GekkoScience 2Pac, I setup cgminer 4.10.0, (compiled it with icarus) and started mining.
Without changing anything the hash rate is far below expected: in slushpool it is from about 100Mh/s till about 1Gh/s, usually about 300-600Mh/s.
I have connected it to a usb port on my PC (till the hub I ordered is here). Is that responsible for low hash rate?
What I see in cgminer is:

Is it OK? Shouldn't I see some frequency? How can I alter frequency?
When I try to start cgminer with I get
Thank you!

A little background info for more detail.. CJ is my cousin. I was recently in Indianapolis to take care of my ill Grandfather who was on hospice. I am very experienced with these (and the original COMPACS) for those who don't know me.

While I was there, I ordered two 2PAC's from sidehack while there & set everything up for him. We ordered 2 USB Y splitter cables, used a decent powered USB hub, had a 120mm box fan that provided excessive cooling, & were running both sticks at 200MHz with no problems for several weeks.

A few weeks later, my Grandfather passed & I returned home. I left 1 of the 2PACS with my cousin (and it was running fine before I left), & took the other with me. After a few days of being home, the stick began acting up as he described. I spent over an hour on the phone with him in an attempt to help get it running, but nothing worked. Told him to order a USB multimeter so we could have a more accurate reading of the electrical specs than his old circuit tester provided us with while I was there setting them up.

He shipped the stick to me earlier today (just outside Philadelphia, PA), & I will attempt to get it working. I will update once I receive the stick, but wanted to rule out the possibility of user error (even though my cousin is in IT & a whiz with computers) before reaching out to sidehack for warranty repair.

Thanks for all of the help in the meantime (my cousin was having some trouble believing me when telling him about how willing this community is to help one another, so it's great he got to see for himself)!

2017 JUNE 12 UPDATE:
I received the 2PAC from my cousin in the mail today. Using a USB 'Y' cable to supply sufficient power, a regular/standard USB multi-meter, & a 35W powered USB multi-meter (to add or decrease power). Along with several other things I tried to get it hashing, I used different versions of CGMiner. Here are some of the results:

For some reason sounds like the chip is not getting enough power to run anymore.
Move around the PC and try a port on a different controller or use a powered hub (recommended).

I have tried all the ports, on multiple computers, and with a powered hub....with same results.  :-(
