I'm not sure that a mini-OS makes sense; I'd rather just see the
standard USB support improve.  A good first step would be to gather
together all the available USB documentation, starting with the actual
on-the-bus protocols and programming the host interfaces (OHCI, UHCI,
etc.).  That will be a fearsome pile, alas.

The first obstacle to using USB for storage devices is that USB 1 is
slow and USB 2 (the original USB 2, not the USB 1 that has been
renamed to USB 2) is fast enough but requires new code to run OHCI
interfaces (yes, that's redundant).
