Installs with any Razer product, including keyboards and mice. For the Razer Lycosa keyboard, it allows the function of the volume and music player buttons. Macros and profile switching for this and some other Razer devices will work without therazerhid.exe, since the macros are recorded and implemented in the keyboard itself. You just need the configurator to write to the keyboard memory and record the macros to it.
