Zephyr USB CDC example didn't work

[danielHC]

Hi Nordic,

I want to have a cli function over USB, I tried example under "samples/subsys/usb/cdc_acm", looks it can run but nothing show on console, anything I missed? Thanks in advance

board: nrf5340dk

SDK: NCS v1.9.1

build: nrf5340dk_nrf5340_cpuapp

I believe the example echos data sent. Have you tried typing something?

I was only playing with this example a couple hours ago with putty. Just tried Tera Term VT and it seems to work out of the box.

Hi Craig
Shouldn't I see this message on console?

[Craig12]

I don't see this on my console, and I can't find it in the code. Maybe it has been removed in a later version.

I assume you are seeing characters being echoed over the USB CDC Interface?

[Craig12]

Looks like it (static const char *banner1 = "Send characters to the UART device\r\n";) was removed on the 8th May 2019, but  the readme never fixed:
