Hi
I have recently bought a laptop and I ran into issues with it's internal devices, every time I start linux on that device (doesn't matter whether it is an ISO or a finished installation) Right after I get through systemd, the device gets stuck in a loop, where it tries to connect & disconnect a specific device.
Here's the dmesg messages:
```
[162.160184] usb 3-8: new high-speed USB device number 12 using xhci_hcd
[162.308559] usb 3-8: New USB device found, idVendor=2808, idProduct=a658, bcdDevice= 1.10

[164.626933] usb 3-8: Manufacturer: Realtek USB2.0 Finger Print Bridge
[206.783497] usb 3-8: USB disconnect, device number 13
```
That's the only thing I am able to get, as this is the only thing that gets printed out on the screen, and when this happens, the laptop gets basically frozen (cant login inside the DM, switching tty works, but logging in doesn't work - pressing enter has no effect)
What's weird is, that few times I've gotten past this, but right after rebooting I run into this issue again and again. I've tried to add a udev rule, to ignore this device, but that doesn't seem to do anything (it might be wrong, as I don't have much experience with custom udev rules)
```
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="2808", ATTR{idProduct}=="a658", RUN="/bin/sh -c 'echo 0 > /sys/$devpath/authorized'"
```
I can't seem to get around this issue at all, the only way to install the device was by using an old 2021 ISO, that I had lying around, which didn't have this problem.

By updating the udev rule it seems the device no longer connects and disconnects and I am able to get into a display manager. But there still seems to be an issue with lot of stuff, systemctl times out, doas too but no errors except for timeouts get logged out in journalctl.
```
SUBSYSTEMS=="usb", ATTPR{idVendor}...., ATTR{authorized}="0"

Updating to latest kernel resolved my problems.
