Nothing much comes to mind here. If AbelCam is listing your PTZ in the pull-down box on the PTZ configs tab (actually for a Sphere it lists 2 items: PTZ-1 and PTZ-2) then it is recognizing your cam's PID okay.

If you haven't already, experiment with PTZ-1 and PTZ-2. Spheres are a bit odd in that they report 2 PTZ's and there doesn't seem to be any solid rule as to whether 1 or 2 is the right one. Varies from system to system.

Running a debug log might provide some useful info. On the Web tab, check the box at the bottom for Write Debug File. Then Save, then re-start AbelCam (so the debug captures start-up, where all devices get enumerated). Try to move the PTZ a bit, then un-check Write Debug File and Save again. See if the resulting logfile tells you anything interesting.

If none of this gets you anywhere, send in the debug file. See instructions for sending on the Support Page.
