Hm, I can see that. I've only observed the behaviour Damon describes with a single embedded system, and there was no solution: It was the SBC's vendor firmware that simply waited for that USB bulk device to do something. That's not standard, it was not fixable, and it's honestly nothing the B200 can do about: it's not pretending to be e.g. a storage device.
