The fixed blackwidow.py script. Use Zadig and libusb

readme.md

The following tutorial will help you setup a python script that will allow you to use the macro keys on your Razer Blackwidow keyboard with programs like AutoHotKey without the need for Razer Synapse.

Download and install python ( i used version 2.7.13 )

Download and install libusb-win32

Run the libusb-win32 "filter wizard"

select "Install a device filter" and click next

look for your Razer Blackwidow keyboard in the list of devices and click install

Download Pyusb

To install Pyusb open a command prompt window where "setup.py" is located and run the command "python setup.py install"

Download this Python script

Run the libusb-win32 "Test (win) Program" and open the Python script in a text editor

Make sure that the value of "VENDOR_ID" is the same as "idVendor" in the TestLibUsb window

Make sure that the value of "PRODUCT_ID" is the same as "idProduct" in the TestLibUsb window

Make sure that the value of "USB_INTERFACE" is the same as "bInterfaceNumber" in the TestLibUsb window

Save and run the Python script

The macro keys on your Blackwidow keyboard should now work without the need of razor synapse and should now correspond to the following keys:

m1 = f13

m2 = f14

m3 = f15

m4 = f16

m5 = f17

Fn = f24

The python script will need to be run every time you unplug / plugin your keyboard or reboot your PC; however the script can be made to run on startup. Steps 10 to 13 may need to be repeated if you change the usb port your keyboard is plugged in to.
