Is it expected that removing a usb serial adapter while you have a

expected if you remove a mounted umass device so wanted to see if its known
behavior for serial before I file a pr. (adapter is <FTDI usb serial
converter, class 0/0, rev 1.10/4.00, addr 3>)
-stable version as of the 25th march, (may have existed before but the
first time I forgot to close tip before removing the device was on this
version.)
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!
