There are no plans to document it beyond what is already available at linux-usb.org or by reading the source code. Besides, it's so easy to use that it hardly needs any documentation. Basically, you just modprobe it. (There are some module parameters you can set if you want to force the emulated connection to be SuperSpeed vs. High speed vs. Full speed, or if you want to emulate more than one controller. Unless you're doing something special, you can ignore them.)
