0034 Description
0035 -----------
0036
0037 This driver implements the sysfs interface for the Corsair PSUs with a HID protocol
0038 interface of the HXi and RMi series.
0039 These power supplies provide access to a micro-controller with 2 attached
0040 temperature sensors, 1 fan rpm sensor, 4 sensors for volt levels, 4 sensors for
0041 power usage and 4 sensors for current levels and addtional non-sensor information
0042 like uptimes.

0076 Usage Notes
0077 -----------
0078
0079 It is an USB HID device, so it is auto-detected and supports hot-swapping.
0080
0081 Flickering values in the rail voltage levels can be an indicator for a failing
0082 PSU. The driver also provides some additional useful values via debugfs, which
0083 do not fit into the hwmon class.
