Right, since it does not need any extra resources. Probably not the best example. > I2C and SPI should at this point be sane for hotplugging as needed > for an ldisc. I guess hotplugging support in the downstream kernel frameworks would be needed anyway with usb-serial being USB based. > And having an ldisc also has another nice effect.

Right. > It also means that if Bus Pirate 5 changes USB uart nothing breaks. And it means no auto-support. Which would be fine in case of Bus Pirate, since its mainly a developer device and some people may actually prefer the IMHO anoying serial interface. Let's forget that example. -- Sebastian
