I have a dv7-2170us laptop.

I performed a clean install with Windows 7 Home Premium 64-bit.

I used the drivers for this laptop model from the HP site.

I'm getting a few unknown devices in Device Manager.

I've tried un-installing the devices and re-installing to allow Windows to re-detect but no drivers are found.  See pictures below, what devices could these possibly be referring to?

 

I have all the necessary drivers loaded that I am aware of and I installed any driver that looked valid from the HP drivers site.

EDIT: Everything works!  Thanks for the tip Daniel.  I googled how to identify hardware id's and came up with this site http://www.pcidatabase.com/ , punched in the device id's and bam, it WAS the card reader.  Weird because it was working perfectly.  But I downloaded the driver anyway and re-installed and this resolved the issue.

 

 

=============================================

 

I tried the Intel Chipset Utility, didn't work. Here's the hardware id's though:

 

 

If you look closely you'll notice that each of these devices are in fact different.

That is the Card Reader. .not sure which you have JMicron or Realtek.Just try both. The other unknown is probably the  HP ProtectSmart Hard Drive Protection software.

The card reader already works, I have it setup with a SD Card for Readyboost and I already have the HP Protectsmart Hard Drive software loaded.  These unknown devices aren't those unfortunately.

@jojogwapo

 

When you say you 'rebooted' your laptop are you saying that you reinstalled Windows? If so I assume that you did not use Recovery Manager on the laptop or Recovery Discs since you are missing drivers?

 

Have you installed the  ATI Radeon Graphics driver from your support page? The device you posted hd id of is Validity Fingerprint Sensor-also on your driver page.
