I want to connect my Huawei Mate 20x android phone to the pc for adb debugging, but I get some errors in dmesg and the device does not show up in any list (lsusb, adb devices).
The android device has "adb debugging via usb", "allow debugging while loading only" and related options enabled. I might be missing some more obscure security settings here, but I followed the tutorials I could find.
I own two other (way older) android devices, which are connecting without problems, so the kernel settings on my pc should be fine. I tried kernel versions 5.11.10 and 6.4.3 (gentoo sources).
These are the messages from dmesg

So I just solved this using a solution from a thread in ubuntu forums from 2011.
I'll include the solution instead of deleting this post, just in case someone else stumbles into the same problem:
It seems to be a problem with usb autosuspend activating as the phone switches into power loading mode once it gets connected to usb (even if deactivated in the phone's settings).
It seems to be necessary to disable autosuspend for usb on the pc.
