NUCLEO_L552ZE_Q support for USBDEVICE

Hi,

as far as I could see the NUCLEO_L552ZE_Q does not support USBDEVICE yet.

I have a rudimentary patch ready, there is still some work to be done. Can I already open a pull request for it and still work on it, or should I wait until I am finished?

That being said, I struggle a lot with running the unit tests, are they required to work when submitting the pull request?

Best,
Chris

I think you can start pushing a pull request,
and yes, I agree USB tests are not simple to execute…

For future reference: STM32L5: enable USBDEVICE by chrJost · Pull Request #14340 · ARMmbed/mbed-os · GitHub

I could not get the tests to work, I do hope that the CI Tests will work.
