Hello all, if somebody has interrest, we have USB stack for NXP PDIUSB, LPC2148 and some other MCUs which has been used with SDCC. We use it for our own vendor specific protocol in USB <-> uLan converter, firmware loaders etc., but it has been successfully used for HID device development. It would be nice to have CDC for it, because I hope, it could be used to use it as COM/tty under Linux and Windows without writting specific drivers. We plan to do that, but have not found time for CDC yet.
