[ X11 configured with Logitech serial mouse on COM2, /dev/tty01 ... ]

Yes, that's normal, it has to complain because it can't make the connection
that it "expects".  Shortly after that, however, you should get the root

Try telling xconfig that you have a Mouse Systems mouse rather than a
Logitech serial.  That has worked for me and others with the same problem.
I promise you that unplugging and plugging the mouse again will do little
more than wipe the connector pins.

I think it has to do with the driver and mouse not getting out of the same
side of the bed at the same time.  The MSC mouse driver is less fussy and
seems to work when the Logitech driver doesn't.

I'd love to take credit for this pearl, but John Crittendon from SunRiver
told me about it (uunet!sunriv!johnc).  Also, stick with 1200 baud for
the serial mouse.  Faster isn't better, it might not even work at all.
I don't know why MSC works better than the Logitech definition, but it
does.  Please try this and confirm that it solven your problem (if it did)
so that my statistical sample size exceeds three :-)
