I checked that.

The attached dump is started after the xhci and usbmon module are loaded
(the device is not visible when only ehci/uhci are loaded).

I then switched the device manually to configuration 3 via sysfs and
loaded the cdc_mbim module and it's dependencies via modprobe.

Afterwards I ran the mbimcli --query-device-caps command as before.

Maybe you can see anything from that.
