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.
