I recently changed my old laptop for a new HP ProBook 450 G2. The drivers installation on my Windows 7 Home Premium (64-bit) were pretty straight forward, except for the following two devices which were shown as not supported in the Device Manager:

1. Other devices -> Unknown device:

   Hardware Ids: ACPI\HPQ6007
   Device Instance Path: ACPI\HPQ6007\3&33FD14CA&0
   Parent: ACPI\PNP0A08\2&daba3ff&1
   

2. Other devices -> PCI Data Acquisition and Signal Processing Controller:

   Hardware Ids:
   	PCI\VEN_8086&DEV_9C24&SUBSYS_2248103C&REV_04
   	PCI\VEN_8086&DEV_9C24&SUBSYS_2248103C
   	PCI\VEN_8086&DEV_9C24&CC_118000
   	PCI\VEN_8086&DEV_9C24&CC_1180
   Compatible Ids:
   	PCI\VEN_8086&DEV_9C24&REV_04
   	PCI\VEN_8086&DEV_9C24
   	PCI\VEN_8086&CC_118000
   	PCI\VEN_8086&CC_1180
   	PCI\VEN_8086
   	PCI\CC_118000
   	PCI\CC_1180
   Physical Device Object name: \Device\NTPNP_PCI0014
   Device Instance Path: PCI\VEN_8086&DEV_9C24&SUBSYS_2248103C&REV_04\3&33FD14CA&0&FE
   Parent: ACPI\PNP0A08\2&daba3ff&1
   

The first one turned out to be the driver for “HP 3D DriveGuard 6” which I didn’t install because my SSD drive won’t benefit from such a feature.

The second one was a more interesting case. It turns out that not all HP drivers were listed when I selected my operating system “Microsoft Windows 7 Home Premium (64-bit)” at the HP drivers website. I had to change the OS to “Microsoft Windows 7 Home Professional (64-bit)”, so that I get the option to download the “Intel Chipset Installation Utility” which resolved the missing drivers.
