This is a multi-threaded multi-pool FPGA and ASIC miner for bitcoin.
This fork has been modified to add a driver for the bitaxe miner. https://github.com/skot/bitaxe
This code is provided entirely free of charge by it's programmers.
If you wish to support it, simply mine at https://kano.is/
This code is licensed under the GPLv3. This means that the source to any
modifications you make to this code MUST be provided by law if you distribute
modified binaries. See COPYING for details.

EXECUTIVE SUMMARY ON USAGE:
Single pool:
cgminer -o stratum+tcp://pool:port -u username -p password
Multiple pools:
cgminer -o stratum+tcp://pool1:port -u pool1username -p pool1password -o stratum+tcp://pool2:port -u pool2usernmae -p pool2password
Single pool with a standard http proxy:
cgminer -o "http:proxy:port|stratum+tcp://pool:port" -u username -p password
Single pool with a socks5 proxy:
cgminer -o "socks5:proxy:port|stratum+tcp://pool:port" -u username -p password
Single pool with stratum protocol support:
cgminer -o stratum+tcp://pool:port -u username -p password
The list of proxy types are:
http: standard http 1.1 proxy
http0: http 1.0 proxy
socks4: socks4 proxy
socks5: socks5 proxy
socks4a: socks4a proxy
socks5h: socks5 proxy using a hostname
If you compile cgminer with a version of CURL before 7.19.4 then some of the above will
not be available. All are available since CURL version 7.19.4
If you specify the --socks-proxy option to cgminer, it will only be applied to all pools
that don't specify their own proxy setting like above
After saving configuration from the menu, you do not need to give cgminer any
arguments and it will load your configuration.
Any configuration file may also contain a single
"include" : "filename"
to recursively include another configuration file.
Writing the configuration will save all settings from all files in the output.

SETTING UP USB DEVICES on WINDOWS/LINUX/OSX
WINDOWS:
On windows, the direct USB support requires the installation of a WinUSB
driver (NOT the ftdi_sio driver), and attaching it to the chosen USB device.
When configuring your device, plug it in and wait for windows to attempt to
install a driver on its own. It may think it has succeeded or failed but wait
for it to finish regardless.
If the driver doesn't allow mining, cgminer will get a "USB init," error message
i.e. one of:
open device failed, err %d, you need to install a WinUSB driver for the device
or
claim interface %d failed, err %d
This means you need to associate your device with the WinUSB driver.
The best solution for this is to use a tool called Zadig to set the driver:
https://sourceforge.net/projects/libwdi/files/zadig/
They've moved the latest versions to:
https://zadig.akeo.ie/
This allows you set the driver for the device to be WinUSB which is
required to make it work if you're having problems.
With Zadig, you will need to run it as administrator and if your device is
plugged in but you cannot see it, use the Menu: Options -> List All Devices
and you should be able to see the device in the drop down list as something
like: "CompacF Bitcoin Miner"
Choose the install or replace driver option and select WinUSB.
When you first switch a device over to WinUSB with Zadig and it shows that
correctly on the left of the Zadig window, but it still gives permission
errors, you may need to unplug the USB miner and then plug it back in. Some
users may need to reboot at this point.
LINUX:
The short version:
sudo cp 01-cgminer.rules /etc/udev/rules.d/
The long version:
On linux, the direct USB support requires no drivers at all. However due to
permissions issues, you may not be able to mine directly on the devices as a
regular user without giving the user access to the device or by mining as
root (administrator). In order to give your regular user access, you can make
him a member of the plugdev group with the following commands:
sudo usermod -G plugdev -a `whoami`
If your distribution does not have the plugdev group you can create it with:
sudo groupadd plugdev
In order for the USB devices to instantly be owned by the plugdev group and
accessible by anyone from the plugdev group you can copy the file
"01-cgminer.rules" from the cgminer archive into the /etc/udev/rules.d
directory with the following command:
sudo cp 01-cgminer.rules /etc/udev/rules.d/
After this you can either manually restart udev and re-login, or more easily
just reboot.
OSX:
On OSX, like Linux, no drivers need to be installed. However some devices
like the bitfury USB sticks automatically load a driver thinking they're a
modem and the driver needs to be unloaded for cgminer to work:
sudo kextunload -b com.apple.driver.AppleUSBCDC
sudo kextunload -b com.apple.driver.AppleUSBCDCACMData
If you are running an old Mac and desktop performance is noticeably affected,
adding the --mac-yield option may help, but also may slow down mining.
There may be a limit to the number of USB devices that you are allowed to start.
The following set of commands, followed by a reboot will increase that:
sudo su
touch /etc/sysctl.conf
echo kern.sysv.semume=100 >> /etc/sysctl.conf
chown root:wheel /etc/sysctl.conf
chmod 0644 /etc/sysctl.conf
Some devices need superuser access to mine on them so cgminer may need to
be started with sudo
i.e.:
sudo cgminer <insert commands here>
There is a hidden option in cgminer to dump out a lot of information
about USB that will help the developers to assist you if you are having
problems:
--usb-dump 0
It will only help if you have a working USB mining device
---
Advanced USB options:
The --usb option can restrict how many USB devices are found:
--usb 1:2,1:3,1:4,1:*
or
--usb BAS:1,BFL:1,MMQ:0,ICA:0,KLN:0
or
--usb :10
You can only use one of the above 3
The first version
--usb 1:2,1:3,1:4,1:*
allows you to select which devices to mine on with a list of USB
bus_number:device_address
All other USB devices will be ignored
Hotplug will also only look at the devices matching the list specified and
find nothing new if they are all in use
You can specify just the USB bus_number to find all devices like 1:*
which means any devices on USB bus_number 1
This is useful if you unplug a device then plug it back in the same port,
it usually reappears with the same bus_number but a different device_address
You can see the list of all USB devices on linux with 'sudo lsusb'
Cgminer will list the recognised USB devices
with the '-n' option or the
'--usb-dump 0' option
The '--usb-dump N' option with a value of N greater than 0 will dump a lot
of details about each recognised USB device
If you wish to see all USB devices, include the --usb-list-all option
The second version
--usb BAS:1,BFL:1,MMQ:0,ICA:0,KLN:0
allows you to specify how many devices to choose based on each device
driver cgminer has - the current USB drivers are:
AVA, BAS, BFL, BF1, DRB, HFA, ICA, KLN and MMQ.
N.B. you can only specify which device driver to limit, not the type of
each device, e.g. with BAS:n you can limit how many BFL ASIC devices will
be checked, but you cannot limit the number of each type of BFL ASIC
Also note that the MMQ count is the number of MMQ backplanes you have
not the number of MMQ FPGAs
The third version
--usb :10
means only use a maximum of 10 devices of any supported USB devices
Once cgminer has 10 devices it will not configure any more and hotplug will
not scan for any more
If one of the 10 devices stops working, hotplug - if enabled, as is default
- will scan normally again until it has 10 devices
--usb :0 will disable all USB I/O other than to initialise libusb

MULTIPLE POOL CONNECTIONS
FAILOVER STRATEGIES WITH MULTIPOOL:
A number of different strategies for dealing with multipool setups are
available. Each has their advantages and disadvantages so multiple strategies
are available by user choice, as per the following list:
FAILOVER:
The default strategy is failover. This means that if you input a number of
pools, it will try to use them as a priority list, moving away from the 1st
to the 2nd, 2nd to 3rd and so on. If any of the earlier pools recover, it will
move back to the higher priority ones.
ROUND ROBIN:
This strategy only moves from one pool to the next when the current one falls
idle and makes no attempt to move otherwise.
ROTATE:
This strategy moves at user-defined intervals from one active pool to the next,
skipping pools that are idle.
LOAD BALANCE:
This strategy sends work to all the pools on a quota basis. By default, all
pools are allocated equal quotas unless specified with --quota. This
apportioning of work is based on work handed out, not shares returned so is
independent of difficulty targets or rejected shares. While a pool is disabled
or dead, its quota is dropped until it is re-enabled. Quotas are forward
looking, so if the quota is changed on the fly, it only affects future work.
If all pools are set to zero quota or all pools with quota are dead, it will
fall back to a failover mode. See quota below for more information.
The failover-only flag has special meaning in combination with load-balance
mode and it will distribute quota back to priority pool 0 from any pools that
are unable to provide work for any reason so as to maintain quota ratios
between the rest of the pools.
BALANCE:
This strategy monitors the amount of difficulty 1 shares solved for each pool
and uses it to try to end up doing the same amount of work for all pools.
---
QUOTAS
The load-balance multipool strategy works off a quota based scheduler. The
quotas handed out by default are equal, but the user is allowed to specify any
arbitrary ratio of quotas. For example, if all the quota values add up to 100,
each quota value will be a percentage, but if 2 pools are specified and pool0
is given a quota of 1 and pool1 is given a quota of 9, pool0 will get 10% of
the work and pool1 will get 90%. Quotas can be changed on the fly by the API,
and do not act retrospectively. Setting a quota to zero will effectively
disable that pool unless all other pools are disabled or dead. In that
scenario, load-balance falls back to regular failover priority-based strategy.
While a pool is dead, it loses its quota and no attempt is made to catch up
when it comes back to life.
To specify quotas on the command line, pools should be specified with a
semicolon separated --quota(or -U) entry instead of --url. Pools specified with
