No, I did not.  By the time I got a chance to follow up on this, new
kernel version were available, and I have not had time to test any of
them (the machine using this hardware is constantly in use, including
the serial device itself).  I will see if I can follow up by connecting
the device to a more expendable machine at some point when the serial
ports won't be needed on my main machine for some time.

I will e-mail again when I do finally manage to do that.
