I don't know exactly how u_serial.c works, but from a brief look it looks like it just provides some library, that then gets #include'ed by other drivers, e.g., serial.c or cdc2.c. Which then implement specific USB functionality, create USB device, configuration, interface descriptors, etc. So, you would need a ptp.c, implementing ptp USB device descriptors, and then you would need a user-space daemon to implement the actual protocol. How would this be any better? > I guess it would be a lot simpler for userland and we wouldn't tie ptp > to one userland application. Don't see how this would be simpler and you would then be tied to a kernel module _and_ a user-space application.
