This might be actually RPiv3 usb driver issue and nothing to do with pyOCD, but that is current feeling based on tests that we did. Anyway, I propose to mention in readme/documentation that pyOCD doesn’t work with RPi.

Just FYI, after some woes regarding installation of cmsis-pack-manager, and a separate issue with USB which I still have to investigate, pyocd seems to run fine on a Raspberry Pi, ubuntu 18.04.2.
