=Thanks To The Community=
=================
As with the original compac, this project would not have even been possible without the great support from the community.
A big thanks to everyone who pitched in; whether through signature campaigns, discussion, product ordering, or anything else.

=How to Run=
=================
At the moment, you will need to build cgminer with the latest gekko driver to mine with the 2Pac.
The driver is under active development in an fork of ckolivas/cgminer.
A pull request will be redirected to the ckolivas/cgminer repo once the code approached a stable point.
Run syntax:
*nix [if not root level privileges, see Q&A]

=Expected Performance=
=================
The expected performance of the 2Pac is 0.11*MHz=GH. For example, 150MHz gives 16.5 GH (theoretical expectation).
Rough chart of power draw:

=================
=Cooling=
=================
If you run the miners over about 100MHz it is strongly advised to cool them with a fan. The cooling requirements are fairly low and unless you're trying to run 250MHz or above almost any fan at all will do.
===============
=Basic Q&A / Troubleshooting=
===============
Q. Can I run this cgminer build with the original Compac?
Yes. The original Compac will register with separate device name from the 2Pac.
Q. Can I run this cgminer build with other USB miners?
It is recommended to use the
official cgminer build for better support of other devices.
It is best to keep the 2Pac separated from other devices until this fork of cgminer can be regression tested.
Q. How can I set a different frequency for the 2Pac vs the Compac?
cgminer will accept one or both parameters for the stick.
--gekko-compac-freq 200 --gekko-2pac-freq 150
Q. How many 2Pac(s) can I run at a time?
One. Review the power chart in the performance section above.
You can add more sticks using a 1-2A per port powered hub (recommended).
Hub thread:
https://bitcointalk.org/index.php?topic=1779423.0Q. Something doesn't look correct..
Here are some of the more common ways to address issue(s):
Any email asking for support will be met with "If you didn't buy from me, talk to the person you bought it from."
Q. How do I get the latest version of the driver and code?
Updates to main cgminer and gekko updates will be checked in regularly.
If you are following along with the instructions, enter the cgminer directory, pull and rebuild:
cd ~/git/vthoang/cgminer/
git pull
...
Q. I tried the latest code and am certain the old one works better, how do I go back?
git reset --hard 495461c
CFLAGS="-O2" ./autogen.sh --enable-gekko
make -j 2
Q. How to get past "USB init, open device failed" ... "you don't have privilege to access" error.
cd ~/git/vthoang/cgminer/
sudo usermod -G plugdev -a `whoami`
sudo cp 01-cgminer.rules /etc/udev/rules.d/
sudo reboot
