[libusb] How to use USB SCSI Pass Through Interface in libusb?

[Tao W. <twa...@gm...>]

Hi, everyone,

I'm thinking about a cross platform solution to communicate with Pentax
camera, which using USB (Mass Storage) SCSI Pass-Through Interface, with
'F0' vendor specific SCSI commands.

The current solution is via '/sys/class/scsi_generic' with `ioctl(fd,
SG_IO, xxx)`, but it's not a portable solution.

I didn't find any example of how to use SPTI via libusb. Can anyone give me
some help about how to do it? Thanks.

Best Regards,
Tao Wang
