 This will be needed when you edit **config.h**.
 
 ### 2. Remove Drivers from Device Manager(Windows)
-Windows only. Linux, OSX and other OS's doesn't require this. It looks like Windows keeps using driver installed when device was connected first time even after the device changes its configuration.
