I would expect that the problem is identical in the sense that with a
connection established, you have an open file descriptor which is
associated with a serial device that uses USB.

So, yes, I would expect this behaviour based on the track record.
Should it happen?  The answer is no.  File a PR?

Also, I'd like to know what USB serial adapter you're using (brand,
model, and a website of it if possible), for unrelated reasons.  Thanks!
