[RFC 3/6] usb/uas: hide direction in res5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The UAS protocol does not encode the transfer direction. It should be
learned from the cdb.
This patch temporary stores the direction in a reserved field until I
figure out how to obtain this information from target
