Kernel error during usb_modeswitch for usb lte modem (navio2)

I’m trying to connect an lte modem ( Alcatel L800 ) for navio2+RPi3.
But usb_modeswitch brought some error messages.
What’s wrong with this?

Wow, that’s unfortunate. We’ll try to repro and then file a bug report or look if someone has already done that.
