I have a Corsair HX1000i PSU, but looks like I can't quite get information for it in the vfs /sys/class/hwmon*; this is my output:
ema@scv:~$ ls -la /sys/class/hwmon/

My device is revision 2, id: 1b1c:1c1e (I can see it in lsusb):
...
Bus 001 Device 003: ID 1b1c:1c1e Corsair HX1000i Power Supply
...
And I'm running on Ubuntu 22.04 - which is using kernel 5.15.0. Looking at the kernel sources seems like rev 2 of my PSU is only supported from kernel 6.1 forward in terms of appearing in hwmon* vfs.
Am I correct in expecting this adaptor to appear in this vfs once my kernel gets updated to 6.1+?
What shall I do if I want to query this device myself now? Shall I just use the hid part of the driver to communicate with the low level USB interface? Is there any library to facilitate USB I/O on Linux (happy to write - or borrow - c code)?
I guess libusb should do whilst I wait Ubuntu to update the kernel?
Thanks!
