The index in usb_string array is defined by the gadget. The gadget can
choose which index entry it assigns for the serial number and which the
product name. The gadget has just to ensure that the descriptor contains
the proper string id which is assigned by composite.
If the composite layer knows the index of the "default" information
which will be overwritten by module parameters, it can be used later to
overwrite it.

I have no idea what I've been thinking while I was doing this in the first
place. Now the strings are initialized properly and reported by lsusb.

This fabric uses the target framework to provide a usb gadget
device. This gadget supports the USB Attached SCSI Protocol (UASP)
and Bulk Only Transfers (BOT or BBB). BOT is the primary interface,
UAS is the alternative interface.
It has been tested with dummy_hcd on HS and SS. On SS USB3 are
supported. I also took my omap device and tried it there against
WindowsXP. UAS implements basic command passing (i.e. read/write
requests) and TASK MANAGEMENT functions are missing.
I had to add a little of error recovery to BOT because Windows was
issuing some strange commands and it does not complain after the
gadget responded with CSW.status=1.
(nab: Move to drivers/usb/gadget as per Sebastian to address legacy
limitations for built-in gadget code)
