I tried the gpm-mouse-test program and it is more complete than the man
page indicates. It does try several baud rates. It appeared to be able
to see the mouse present but was not able to detect the protocol. I
don't know whether that was because of a bug in the program or the mouse
uses a custom protocol. As I said in an earlier post I used the mouse
(long ago) on Debian Jessie with gpm and it worked with msc protocol.

The gpm-mouse-test program also did not detect the regular USB mouse so
it may have some problems.
Best regards,
Fred
