Then I would like to see an lsusb listing for 19d2:1225 with an SD-card

which is for the windows install cd-rom.
There are almost no 3G dongles having the SD-card interface active in
default (non-switched) mode.
Though I see your point. Is the switching desirable at all for this
device or do I need to block the device on the SCSI level?

However, when I reinstall usb_modeswitch I see that the storage
functionality is unnecessary to switch this device.

Yes but there are other 19d2:1225 devices which don't have dual-mode
(19d2:1403 RNDIS or 19d2:1405 ECM) they do only have one of the modes
and they don't auto-flip so they need usb_modeswitch.
This is the first 3G dongle I have seen with multiple LUN on the same
USB interface, there has always been one interface for each storage
function in the past. So yes I jumped to conclusion..
Anyway, it would be good if you could block the MMC interface on LUN
level while still having the virtual cd-rom working.
