Thank you very much. I did your suggested quick fix and got my device
working again. I'll try to help others and report the vendor and product
ids to kernel's USB serial subsystem maintainers.
So it's not really usb-modeswitch package's bug but the removed feature
of not loading kernel modules "manually" triggers the underlying
problem. Maybe this bug can be closed.
Thanks!
