Expected behavior compiling with usb support

Actual behavior

[mbed] Auto-installing missing Python modules...

Steps to reproduce

1. make a "hello world" main.cpp including "USBSerial.h"
2. build with mbed compile -t GCC_ARM -m KL25Z --usb

@larsgk Hi Lars, I will take a look and see if I can reproduce the same issue locally.

@larsgk Hi Lars , USBSerial is not currently supported in mbed-os-5 and by default I suspect this is what you are picking up. It is supported in mbed-os-2 which you can easily try in the online IDE. https://developer.mbed.org/handbook/USBSerial

Alternatively if you want to still use mbed-cli then the following steps should get you where you want. (Assuming your test program would be test_usbserial)

mkdir test_usbserial
cd test_usbserial
mbed config root .
mbed add https://developer.mbed.org/users/mbed_official/code/mbed/
mbed add https://developer.mbed.org/users/mbed_official/code/USBDevice/
mbed deploy

<copy/create your main.cpp into test_usbserial

mbed compile -t GCC_ARM -m KL25Z --usb

Please let me know if this fixes your issue.

thanks! - I'll try today :) - when will it land in mbed-os-5?

also - I reported a series of USB bugs/enhancements ... can I ping someone to triage or at least comment? :)

@sg- Sam can you comment on when/if USB Serial will be supported in mbed-os 5 ?

@larsgk We're actively going through the issues on mbed-os currently so you should see some progress. Are there any particular issues which are blocking you ?

[larsgk]

If i get usb working with your suggestion, i will try to do a crude WebUSB implementation e.g. inside usbcdc or usbdevice and do a PR or just attach to the bug (would like to bring a working demo to chromedev next week).

One that is really annoying is the #2838 (block/halt everything when trying to write and nothing connected...). In general: soft connect/disconnect and notifications could be nice to get revisited by someone :)

Another one: if you made an easy API for adding custom headers, WebUSB could (just) use that - #2839

USB updates for mbed OS 5 are planned but not scheduled yet.

[larsgk]

@sg- ok - I hope I can hack a WebUSB solution with mbed (2 or 5) for some demos at chromedev over the weekend tho. Will try to get the mbed-os-2 working with my stuff & do some header fiddling over the weekend. If I manage to get it in time, I'll put the changes in a PR or gist

[larsgk]

Just a post-close note: it works nicely with mbed OS 2 + adding the library (of course). Just posted this: https://github.com/empirikit/empirikit-controller

@larsgk Thanks for the follow-up post, glad you were able to make something awesome!
