  34 Description
  35 -----------
  36
  37 This driver implements the sysfs interface for the Corsair PSUs with a HID protocol
  38 interface of the HXi and RMi series.
  39 These power supplies provide access to a micro-controller with 2 attached
  40 temperature sensors, 1 fan rpm sensor, 4 sensors for volt levels, 4 sensors for
  41 power usage and 4 sensors for current levels and addtional non-sensor information
  42 like uptimes.

  65 Usage Notes
  66 -----------
  67
  68 It is an USB HID device, so it is auto-detected and supports hot-swapping.
  69
  70 Flickering values in the rail voltage levels can be an indicator for a failing
  71 PSU. The driver also provides some additional useful values via debugfs, which
  72 do not fit into the hwmon class.
