Just wanted to say thank you..
I downloaded a few from a few sites that claimed it was THE driver.. but all failed.

Just got this Notebook and reformatted.
HP has most of the drivers except for this..
I've never even seen this hardware before..

I also created a post on HP's website,
after registering my Notebook.

I was struggling to find a driver for "Unknown Device" (Location ACPI\ASD0001).

Toshiba support wasn't very helpful and I came across this page.

The driver provided here solved my problem.

Thank you.
