Hi,
Hi Michael,
Can new UDCs be written for CONFIG_USB_DEVICE or is that deprecated in favour of CONFIG_USB_GADGET?
I have not read any clear statement about this, but IMHO we should consider CONFIG_USB_DEVICE obsolete and move to CONFIG_USB_GADGET.
If that is the case and CONFIG_USB_DEVICE is deprecated, if I want to get USBTTY enabled for a currently unsupported UDC I would need to port USBTTY to CONFIG_USB_GADGET;
Yes, that is right - there is currently no support for the serial gadget.
is there interest in that effort or is there some alternative?
This is very interesting !
There is a lot of boards using CONFIG_USB_DEVICE. We cannot drop then CONFIG_USB_DEVICE, but new boards must use the new interface.
