There’s no guarantee that glfwGetJoystickName() will return the same name on different OSs as the device drivers are different. However in the Windows case this name does seem to be not very useful as it’s the name of the driver and not the joystick - looking into this on the net it appears that Windows makes it awkward to get hold of the actual OEM joystick name properly in some circumstances - I don’t know if this can be fixed but will take a look into it, though I may not be able to reproduce the problem.
