"Re: cdc-acm, I can't think of..." <- > <@jamesmunns:beeper.com> Re: cdc-acm, I can't think of a way it would ever be better? Maybe easier for permissions or something? Or built in flow control signaling of RTS/CTS/dtr whatever that the OS might be able to signal better? But it'd be pretty niche, for how postcard-rpc works, imo. You also then have to pay extra encoding costs. > > Also, nusb is just so damn pleasant to work with over OS serial port APIs. same! that's why I was wondering if there are use cases I'm missing, because otherwise maybe the library can be slightly simplified and the "wire" abstraction ripped out? `postcard-rpc` is pretty opinionated as it is, so maybe it's fine to be opinionated about this as well 🙂
