Added CMT-M373NT to rules to allow it to connect

Collecting some random patches from the web (this was also at glaubitz#3).

Looks good to me.

Unfortunately, we have the list of USB device IDs for NetMD devices in multiple places. Please also add the device ID to netmd/libnetmd.py . We already have the ID in libnetmd/netmd_dev.c , so no change required there.

That's true. There are also some more outdated places that need to be updated when devices are added.

In my friendly fork (which I'll try to get merged upstream eventually) there's a single place to update it (devicedb/minidisc.devids), it generates a udev rules file and data for libusbmd (which is a small library that allows e.g. libnetmd and QHiMDTransfer to share that information from a single place).

It also writes out the database as netmd-js compatible file (not used yet, but once this is merged, maybe we can get the maintainers to use/copy that file) and the Python netmd implementation (since it's kind of nice that it's self-contained, we could use ctypes to load libusbmd, but that'd require it to be built, etc...).

Adding device with that mechanism still involves a diff in multiple places:

thp@b1c5562

But the way this is achieved is simple:

1. Add the entry to devicedb/minidisc.devids
2. Run make -C devicedb
3. Commit the result

So feel free to close this PR for now, and we'll "fix it properly" with the devicedb and libusbmd changes.
