This is how I invoke it:
usb_modeswitch --default-vendor=0x12d1 --default-product=0x1446 -J -Q
There is a bit of a misunderstanding there.
The log is created during the automatic invocation of usb_modeswitch, when
the wrapper (usb_modeswitch_dispatcher) is triggered by the insertion of a
modem.
For extended output during a manual run, add the -W parameter and remove the
-Q parameter.
Note that a bug has been found in the wrapper only recently which prevented
logging of early problems, e.g. when the parameters passed to the wrapper are
not useable and it therefore exits.
This bug has been fixed in usb_modeswitch 2.3.0. There is a description in
the discussion of bug report #805512 (see message #40):
