Wait, you mean the USB storage class from the device side, right?  If
so, just read the USB storage spec, and the SCSI spec that it referrs
to.  There is no need to worry about mmap, or anything other than
"normal" scsi block commands.

This device can't run Linux, it's too small, which is a shame, as Linux
works really well running as a USB "gadget".

good luck,
