Hello, my name is Rusty. That is an Australian model, and the 470 is more popular. Click here, these are the 476 drivers.
Which version of Windows are you using?
Hmm, that's pointing me to the driver for the 470. Have you tried the 470 driver? Model numbers have a series, and the 476 is in the 470 series. The software package at the top of the list is the one when you click Windows 10.
Let me know how it turns out.
