To be a "spaceball" in GLUT it needs to be a HID compliant device that
reports 6 axis. This moment I can't recall whether I have it looking
for particular axis or not (I strongly suspect not). So, without
knowing more details I suspect your serial device is not a HID
compliant device and thus can't be detected by the HiD services and
thus GLUT has no idea it is there.

I have an old serial Spaceball 4000, and noticed yesterday that the
GLUT demo applications have support for spaceballs in them. How do
they detect the spaceball controller? I've tried connecting mine
using a USB-Serial adapter, in case it 'just works', and it doesn't.
Googling finds nothing much more than patches for older versions, and
the release notes for GLUT 3.7.
Is it possible to use this controller with my mac and GLUT?
GLUT uses the HID manager to discover devices, but also relies on the
class of the device in order to know what to do with it. Likely when
you use a USB-Serial adapter, this information is not available (as it
isn't available via serial and the adapter has it's own class). Thus
your serial spaceball doesn't work.

Failure is not an option. It is a privilege reserved for those who try.
