Did you check the location of the pull-up resistor on your device?  It
must be attached to the D+ line.  If it is attached to the D- line then
the gadget will appear to be a low-speed device -- which is exactly
what happened in the log you posted earlier.

Also, did you do what I suggested before, that is, change

#undef DEBUG
#undef VERBOSE

in drivers/usb/gadget/file_storage.c to

#define DEBUG
#define VERBOSE

It doesn't look like you did.
