Run-time enable/disable of individual CDC devices?

[MWP]

Hi all,

Is it possible with TinyUSB to enable/disable individual CDC and MSC devices after tud_init() has been called?
cdcd_init() appears to enabled them all at the same time?

I haven't dug too deep on this yet. I'm hoping there is a simple/existing answer.

Thanks in advance!

No it's impossible by the design of USB protocol.

Ok.
Is there a method, for example, to set CFG_TUD_CDC=2, and only start one of those CDC on tud_init()?

You need 2 set of configuration descriptors, one with 1 port and another one have 2. Then switch them in tud_descriptor_configuration_cb()
