| 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. |
