Well. It's USB Storage, specified as part of the Mass Storage Class
Specification Overview 1.4. It's not part of the Linux usb-storage driver
(yet?), but it's really closely related. For one thing, UAS devices
come up in BBB (aka BOT) mode and have to be switched to UAS mode.
That might be an argument for integration with libusual, or it might
be an argument for integration with usb-storage. I have no idea yet,
I'm still experimenting.
Either way, there's got to be close cooperation, and being in the same
directory seems like a minimum requirement.
