Q: What is a PGA?
A: At the moment, sgminer supports 3 FPGAs: BitForce, Icarus and ModMiner.
They are Field-Programmable Gate Arrays that have been programmed to do Bitcoin
mining. Since the acronym needs to be only 3 characters, the "Field-" part has
been skipped.

**************************************************************************************
* Optional - Install libusb if you need auto USB device detection; required for Ztex *
**************************************************************************************
Go to this url ==> http://git.libusb.org/?p=libusb.git;a=snapshot;h=master;sf=zip
save the file to your local storage. Open the file and copy the libusb* folder to
\MinGW\msys\1.0\home\(your user directory/folder).
Or if you do not want to download the file directly and would like to use git then
Type the following from the MSYS shell in your home folder.
git clone git://git.libusb.org/libusb.git
Run the MinGW MSYS shell
(Start Icon/keyboard key ==> All Programs ==> MinGW ==> MinGW Shell).
Change the working directory to your libusb project folder.
Example: cd libusb-something [Enter Key] if you are unsure then type "ls -la"
Another way is to type "cd libusb" and then press the tab key; It will auto fill.
Type the lines below one at a time. Look for problems after each one before going on
to the next.
./autogen.sh --disable-debug-log --prefix=/MinGW
make
make install
You may now exit the MSYS shell.
Ctrl-D or typing "logout" and pressing the enter key should get you out of the
window.
You will have to copy "libusb-1.0.dll" to your working sgminer binary directory.
You will find "libusb-1.0.dll" in the \MinGW\bin directory/folder.
Use this method if libusb does not work for you on Ztex. Once someone lets us know
Libusb works instead of libusbx then we will remove the section below this line.
Run the MSYS shell and change into the libusb folder as above.
Type ==> make uninstall
Go to this url ==> http://libusbx.org/
Click on the "Downloads" tab.
Click on "releases".
Click on the latest version. I downloaded 1.0.14; yours may be newer.
Do not download from the link that says "Looking for the latest version?".
Click on "Windows"
Click on the file and download it. I downloaded libusbx-1.0.12-win.7z.
Extract the the following from the file and place in where directed.
Copy libusb.h from include\libusbx-1.0 to \MinGW\include\libusb-1.0\libusb.h
Copy contents of MinGW32\static \MinGW\lib
Copy contents of MinGW32\dll to \MinGW\lib
You will have to copy "libusb-1.0.dll" to your working sgminer binary directory.
