=== Overriding entries from the database tarball ===
From its 1.1.7 version, usb-modeswitch searches for device switching data in
the usb-modeswitch-data database tarball [0]. This heavily reduces the
database disk space, but makes configuration investigation harder. To solve
this issue, usb-modeswitch is shipped with a patch that allows administrators
to override the database entries from the tarball [0] with files under /etc.
[0] /usr/share/usb_modeswitch/configPack.tar.gz
= Example =
Let's assume one has a 3G dongle "05c6:1000 Qualcomm", which matching database
entry [1] is 05c6:1000:uMa=Option , but isn't correctly switched. Hacking this
database entry can be done as following:
# cd /etc/usb_modeswitch.d
# tar xzf /usr/share/usb_modeswitch/configPack.tar.gz 05c6:1000:uMa=Option
Now the /etc/usb_modeswitch.d/05c6\:1000\:uMa=Option file will get used by
usb_modeswitch_dispatcher when the "05c6:1000 Qualcomm" device gets plugged
in.
When a correct database entry is found, please report it on the upstream
forum:

[1] One can find exactly which database entry is matching a given device gets
matched with by activating logs (/etc/usb_modeswitch.conf) and reading
them from /var/log/usb_modeswitch*.
