Today, I suddenly got the following error when testing the feature/testing branch of probe-rs

This isn't embedded-test specific, this issue pops up from time to time in probe-rs. I don't know what causes it, unfortunately - the device doesn't send back bits probe-rs expects, but whether it's caused by the device restarting or the bits getting lost in transit or processing, I can't tell.
