Your HP Pavilion g6-2332sa Notebook Computer is almost identical to my sister-in-law's HP Pavilion g6-2210us Notebook Computer. You can read and follow the information posted in this HP forum thread entitled "g7 2233 missing drivers after windows 7 ultimate 64-bit clean install" assistnace with your issue.
The Windows 8 64-bit drivers listed for both computers are almost the same. I installed Windows 7 64-bit on her computer about a month ago and used the following multi-sourced drivers;
AMD Chipset Driver (USB 3.0, SM Bus, etc.)
Realtek FE Family LAN Driver <select download location for 5th item down list>
Realtek PCIe RTS5229 Card Reader Driver <select download location for 2nd item down list>
HP sp54972 Atheros 5xxx/9xxx WLAN Driver
HP sp59620 IDT HD Audio Driver
HP sp58539 Synaptics PS2 Touchpad Driver
and from Windows Update "HP Mobile Data Protection Sensor"
It is possible that the WLAN chipset on your machine is different and may require the use of one of the other drivers.
I also update updated the Synaptics driver to v16.2.21 from the Synaptics website. Some of the above drivers may require the HP Software Framework sp59202. Additionally, the WebCam requires the "VideoCM" package from the "SWsetup" folder in the original Windows 8 install and CyberLink YouCam sp59986.
When finished, there were no unknown device on her system.
