Add the usb id of the HX1200i Series 2023. Update the documentation accordingly. Also fix the version comments, there are no Series 2022 products. That are legacy or first version products going back many many years.

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 additional non-sensor information
|
|
like uptimes.

Usage Notes
|
|
-----------
|
|
|
|
It is an USB HID device, so it is auto-detected, supports hot-swapping and
|
|
several devices at once.
|
|
|
|
Flickering values in the rail voltage levels can be an indicator for a failing
|
|
PSU. Accordingly to the default automatic fan speed plan the fan starts at about
|
|
30% of the wattage rating. If this does not happen, a fan failure is likely. The
|
|
driver also provides some additional useful values via debugfs, which do not fit
|
|
into the hwmon class.
