Sorry, that's not a good argument. It's like saying that support for PPP should be added to the Ethernet driver because the Ethernet driver contains the most common and well-known networking protocol implementation. > The second > reason is the code reuse. Well, in the end you didn't reuse much code. Lots of stuff was added and lots of existing routines were changed, but not much of the existing code is on the UASP path. > But if there is a need to make it standalone > then, considering the UASP class design and implementation, it'll be > not so hard work to implement. Yes, please do. I think the final result will be greatly superior.
