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

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