Dear Linux folks,


On a Dell XPS 13 9360/0596KF, BIOS 2.21.0 06/02/2022, connect a Dell DA300 to the only USB Type-C port on the left side (with a network cable connect), Linux logs the warnings below:

```
$ cat /proc/version

```

Is that a hardware problem, or something the Linux kernel can address?

I created the bug report #216474 [1] with the output of `lspci -nn`, `lsusb` and `dmesg`.


Kind regards,

Paul
