Hello ,
thank you for your answer! Yes I have enabled the Link-Support but the RM-Series has a USB connection for the sensors. So there is a "problem" with the driver. It seems that ther is no driver for the RM-Series anymore. In the Silabs folder there are a driver with these device IDs: VID_1B1C&PID_1C00, USB\VID_1B1C&PID_1C01, USB\VID_1B1C&PID_1C02.
But the device ID from the controller in the PSU is USB\VID_1B1C&PID_1C0A. It uses a default (?) Windows HID driver and the Corsair Link software uses this driver. As you can see the device is in the usbdump.
In my old dump was a unknown device - was a problem with a USB hub - I just fixed it
Thank you for your help
