i believe i am having this same issue on sequoia.
looks like none of the phidget kext files made it into /system/Library/Frameworks/ nor into /system/Library/Extensions
Attemping to re-install the driver pkg does not work.
The first time I tried this, I may have hit "ok" when advised that kernel extensions were blocked.
No Phidgets-related options exist in the System Settings-->General-->Login Items and Extensions, etc.
help?
