UnKnown Devices on PCI Express Root Complex

g6-1305et
Microsoft Windows 8 (64-bit)

After formating my hp laptop with windows8 64bit , I installed all drivers present in the website for g6-1305et . However, in device manager, I got an error below Other Devices-Unknown Device as 'Location: on PCI Express Root Complex, "The drivers for this device are not installed. (Code 28)" . How can I obtain this driver ?

Hi,

 

It's probably the Card Reader driver on the link below.

 

http://ftp.hp.com/pub/softpaq/sp59001-59500/sp59191.exe

 

If it's not, go back into Device Manager, right click on the problem device and select Properties.  Click the Details tab, choose Hardware Ids from the dropdown box and post back with the details shown under Value.

 

Regards,
