Dear reader
EDIT: Solved it, see comment below.
a few hints on how to debug this situation would be greatly appreciated, thanks for your time in advance.
The situation is reproducible by rebooting.
I have a few usb devices directly attached to the motherboard. Those are products of a company called aquacomputer.
I have no active udev rules for these devices.
On reboot I can access the fan-speeds and temperatures provided via loaded kernel_module aquacomputer_d5next I am using kernel 6.6.54-2-MANJARO
After about 30 seconds to 1 minute the driver “vanishes”.
Couldn’t find any hints in journalctl -ke and dmesg
Right after boot. Notice the drivers used.
