Hi everyone,
I'm working on a custom board based on RT1064, using MCUXpresso 11.9.1 and SDK 2.13.0.
Based on the example provided in the SDK, I use a usb composite device with dual CDC vcom interface, and it's working fine.
Due to some extra needs, I extended the usb composite device to act as a triple CDC vcom interface: I modified the sources adding everything necessary (I've defined endpoints, strings, structures, ...). The composite device is enumerated correctly and the first two interfaces are working fine, but the third one isn't working: no data is tranferred to/from the connected host.
Is there any limitation on this scenario?
Many thanks
Biafra
