usb connection issues with Docker containers?

[Lotterleben]

we've had a workshop participant using https://github.com/sleighluxoft/ferrous_workshop who experienced trouble getting a full usb connection to the nrf DK:

root ➜ /workspaces/ferrous_workshop/embedded-trainings-2020/advanced/firmware (main ✗) $ cargo run --bin usb-2
   Compiling usb v0.0.0 (/workspaces/ferrous_workshop/embedded-trainings-2020/advanced/common/usb)
   Compiling firmware v0.0.0 (/workspaces/ferrous_workshop/embedded-trainings-2020/advanced/firmware)
    Finished dev [optimized + debuginfo] target(s) in 1.23s
     Running `probe-run --chip nRF52840_xxAA target/thumbv7em-none-eabihf/debug/usb-2`

  (HOST) INFO  success!
────────────────────────────────────────────────────────────────────────────────

it might be worth investigating this if we have more participants using Docker in the future
