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:
```

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,
