messages.log:
...
: drivers/usb/class/cdc-acm.c: This device cannot do calls on its own. It is no
modem.
: cdc_acm: probe of 1-1:1.1 failed with error -22
: usbcore: registered new driver cdc_acm
: drivers/usb/class/cdc-acm.c: v0.23:USB Abstract Control Model driver for USB
modems and ISDN adapters

Is there any change to get it [If#= 1 ... Cls=02(comm.)] working with current
kernel/modules (cdc-acm?) ??

Steps to reproduce: plug in USB device and have a look to the logs
