With some further digging, I have discovered this is an ELAN1000 touchpad which uses the `i2C` bus instead of the `PS/2` bus which requires different firmware.
The UX305CA apparently does not even have a PS/2 bus physically installed. Only the I2C bus.
I'm not sure how much this helps anyone since that sort of thing is over my head but I thought I would share that.
