Other Devices/Unknown Devices When Installing Windows 8 on HP Probook 6550b

I found three unknown devices when I installed Windows 8 on a HP Probook 6550b. The three unknown devices are actually,

  • JMicron Media Card Reader Drive
       Hardware Ids
         PCI\VEN_197B&DEV_2392&SUBSYS_1619103C&REV_30
         PCI\VEN_197B&DEV_2392&SUBSYS_1619103C
         PCI\VEN_197B&DEV_2392&CC_088000
         PCI\VEN_197B&DEV_2392&CC_0880
       Hardware Ids
         USB\VID_138A&PID_003C&REV_0086
         USB\VID_138A&PID_003C

  • HP 3D DriveGuard
       Hardware Ids
         ACPI\VEN_HPQ&DEV_0004
         ACPI\HPQ0004
         *HPQ0004

  • Validity Fingerprint Sensor (VFS471)
        Hardware Ids
          USB\VID_138A&PID_003C&REV_0086
          USB\VID_138A&PID_003C)


The problem was resolved by downloading and installing three drivers, respectively.

Note that at the time I was installing Windows 8 on the laptop, Windows 8 driver for Validity Fingerprint Sensor was not available on HP's website. I tried the Windows 7 driver and it worked just fine.

After the drivers were installed, you would find the devices listed as follows in Windows Device Manager,
  • JMicro Media Card Reader Driver as "Memory technology devices\JMicron PCIe SD Host Controller" and "Memory technology devices\JMicron PCIe SD/MMC Host Controller"
  • HP 3D DriveGuard as "System devices\HP Mobile Data Protection Sensor"
  • Validity Finterprint Sensor as "Biometric devices\Validity Sensor"

For convenience you may download the drivers for different versions of Windows below:
