FlySky FS-i6X not reliably detected on Arch Linux

Hello,
I’m having an issue with my FlySky FS-i6X controller on Arch Linux. The same controller and cable work correctly on Linux Mint, but on Arch the detection is unstable. The problem is not with the cable or the controller itself, but likely with how Arch detects the device.

Here’s what I’ve tried so far:
Running lsusb
Checking logs with dmesg
Testing with evtest
Several other checks that all point to the same result

The main issue is that plugging in the USB device does not produce any output in dmesg.
Since it works on Mint but not on Arch, this seems related to kernel, udev, or HID handling rather than hardware.

Any help or known issues would be appreciated.
Thanks.

Re: FlySky FS-i6X not reliably detected on Arch Linux

Please post the output of

$ lsusb -tv

with and without the controller plugged in .

For clarity : the controller is directly connected to a usb port on your system and not through some hub or other device ?

Yes, it is directly connected to my usb port.

This is the output before and after plugging the device:

They are the identical.

Re: FlySky FS-i6X not reliably detected on Arch Linux

Damn..

It looks like you have several different ports (usb3 20000M, USB3 10000M, 2x USB2 480M ).
You have tried the device in all physical available ports ?

Does it make a difference if the device is plugged in before a cold start or plugged in after booting has finished ?

Thanks, I just found out that there is a problem with my controller itself.
