Re: [libusb] Looking for host data transfer on UAS end points

[Vasanth V <vas...@gm...>]

Hi Tim,
Thanks for the reply. I was able to do bulk only transfer but I have
business need to use UAS end point. In device descriptor, I see UAS end
points as well along with bulk only transfer. I want to know libusb
sequence of APIs to send SCSI read/write using CMD, Data In, DataOut and
Status end points. Please suggest
Thanks
Vasanth
