Looks like the AT port is completely timing out, it may be due to
incorrect serial port settings. But you also have a cdc-wdm port and a
wwan port; is this modem a QMI/MBIM device? What manufacturer/model is
this?

That is very weird, looks as if the system bus is not working
properly. Does your system have a proper dbus server running? Do you
get those errors in a setup where you don't modify anything?
