With this driver, each device attached to the receiver is recognized as one different device. Recently, a driver called hid-logitech-dj has been added to the Linux kernel. On old Linux kernel, the Unifying receiver is recognized as only one keyboard and/or one mouse device. It's an USB receiver that can be attached up to 6 differents devices (mouse, keyboards…). This keyboard, like many of the new wireless devices from Logitech, uses the Unifying interface. Someone should write code to get the battery status and light meter from Linux: challenge accepted! How the keyboard works This activity being quite energy consuming, it emptied the whole battery. My problem is that there's obviously no way to know the battery status from Linux, the provided application only working on Windows.Īnd one dark night, while fragging on QuakeLive, my keyboard stopped working: it had no battery left.

It has an incredible useful feature: while being wireless, it has no need for disposable or rechargeable batteries, it uses solar power! I'm particularly picky on keyboards, but this one is good.

A year ago, I bought a Logitech Wireless Solar Keyboard K750.
