request for using X55 with Carbon X1 Gen9 under debian bookworm

[Bjørn Mork]

You said you were using Debian Bookworm, so then I assume you are
missing the mhi_wwan_mbim.ko module Loic is referring to.  It was
included with the Debian sid kernel only a couple of days ago:
https://bugs.debian.org/1011395

So upgrade your kernel to version 5.17.11-1 (or newer) as soon as it is
avilable in Bookworm and everything should Just Work (tm)
