The Corsair digital power supplies of the series RMi, HXi and AXi include a small micro-controller with a lot of sensors attached. It can accessed by an USB connector from the outside. This micro-controller provides its data by a simple proprietary USB HID protocol. The data provided are temperatures, current and voltage levels, power used, uptimes, fan speed and a lot more. It is also possible to configure the PSU (fan mode, mono/multi-rail, over current protection). This driver provides access to the sensors/statistics of the RMi and HXi series power supplies. It does not support configuring these devices, because there would be many ways to misconfigure or even damage the PSU.
