Do you understand that the usb_skeleton.c file is totally inappropriate as a model for a mass-storage driver? > I am stuck in data transfer, could not do the data transfer.

There is no such thing as the SCSI transparent command set. "SCSI transparent" means "use whatever command set the relevant SCSI standard specifies". There is non-Linux source code for mass-storage drivers in other open-source operating systems. > 3.
