This is the next generation Razer device configuration tool bringing the Razer gaming experience to the free OpenSource world.
The tool architecture is based on "razerd", which is a background daemon doing all of the lowlevel privileged hardware accesses. The user interface tools are "razercfg", a commandline tool; and "qrazercfg", a Qt based graphical device configuration tool (see screenshot below).

Razercfg does only offer options for features supported by the actual hardware of the mouse. So if the hardware does not support button remapping for example, razercfg will not offer button options, even if the windows driver does. Button remapping on these devices has to be done by xmodmap, xinput or other X11 tools. One exception is profiles, though. If the mouse does not support profiles in hardware, razercfg will emulate 20 profiles in software.

- Q: My buttons don't show up in qrazercfg. What is wrong?
A: Most likely there is nothing wrong with that. If the menu does not show, your mouse does not have support for internal hardware button remapping. See the supported hardware features table above.
- Q: But the Windows driver has a button remapping feature.
So razercfg should have that, too.
A: Razercfg is only supposed to configure the hardware. If you want any software remapping of buttons, which is what the Windows driver does, you need other tools. Your search engine will help you.
The following prerequisites are required to start working on
a driver for a new device.
- to be able to understand and write C code.
- to read the contribution guidelines.
- the original Razer Windows driver for the device.
- some way to sniff the USB-traffic of the configuration sequences with the original Windows driver.
If you lack one of these prerequisites, please try to get all of them before contacting me.
Modern mice most likely implement the "Synapse 2.0" wire protocol or (even more likely) a derivative thereof. That protocol is implemented in librazer/synapse.c. Drivers for mice with synapse protocol are supposed to use that generic code and tell it with feature-flags (enum razer_synapse_features) about slight variations in the wire protocol. See the hw_imperator.c and hw_lachesis5k6.c drivers for examples. New mice most likely require adding more feature flags and modifications to the generic synapse code.
Older devices or device families like the Deathadder for example use their own protocol that differs a lot from Synapse. See the implementations of the individual devices for more information.
Synapse 2.0 Framework is the name of the new Windows driver for Razer
It basically is a one-supports-all solution. One driver for many devices. That's great.
However, what's not to great is the required internet connection, online registration and cloud connection. You guys at Razer, are you serious? A device driver with forced registration and cloud connection? This is ridiculous.
I am not going to play this game. I won't buy any new Razer product that requires an online registration or any sort of internet connection to run the device driver. That also means that I will not work on razercfg support for these devices.
