(In reply to mike from comment #43)
I would try the following:

ATV1
OK
AT!ENTERCND="A710"
OK
AT!UDUSBCOMP=?

The "!ENTERCND" command is necessary only once, in order to enable the
password-protected commands.

The latter command is the one allowing switching modes.
It has provided me with this output on my MC7304:

You can then choose a mode depending on your device and your wishes.

Here I am using mode 8 from this list:

AT!UDUSBCOMP?
!UDUSBCOMP: 8

OK
