Comment 161 for bug 903422

Dave,

Unfortunately, these newer Motorola devices appear as... wait for it... a CDROM drive.

The CD image contains the installer for some windows software that they want you to run, which will send a magic USB packet to the phone to switch it into MTP mode. That's really what's going on. I haven't found any useful information about this online, so it doesn't appear anyone's reverse engineered the magic packet. Sad sad sad.
