Windows 7: Unknown Device

Unknown Device

Device Manager is showing an unknown device and I can't find it.

The Device Instance Path shows: ROOT\LEGACY_CPUZ132\0000 but I can't figure it out.

I do have the Legacy family tree package installed but I can't see how that could be causing the problem.

Any ideas greatly appreciated.

Hello,

1) Uninstall that device, then reboot. If new hardware is found, Windows will automatically install the driver or prompt you.

2) Also, download free Malwarebytes and run a scan.

Hi Sikm,

You can find out exactly what the device is by looking up the Device ID.
  • Open Device Manager and click on the device properties
  • Click on the Details Tab
  • Drop the 'Property' box until you find 'Hardware Id's"
  • You will find some number letter combianations, HID = Hardware ID, VID = Vendor ID, PID = Product ID.
  • In my screen print I've looked up my Logitech Webcam. My PID=0804, My VID = 046D
  • Open the PCIDATABASE website
  • Type your PID where it says device Search and press SEACH, all Devices with that PID show. This is usually enough.
  • If you have multiple Devices, compare the Vendor ID column with your VID

You should now have enough info to search for the drivers for the device.

Please post a screen print, so I can see what you see.

EDIT - You can use the Snip Tool to easily get a picture then upload it with the attach button on sevenforums.

You're welcome. It's never led me wrong. Although Sikm might have found a device without a hardware ID, which means it may be a rouge driver and not a device, perhaps for a non-plug and play device..... if so I think I have a plan..... but baby steps first.

The part the OP has posted "ROOT\...." is a low level driver and there will not be an easy accessible ID. You will not even be able to remove it from the registry without taking permission of the keys first.

@WS - Good Point, I'd kind of skimmed over that and didn't take it in. I like the way you're thinking! Although virus', and Non plug and Play's could be the same.
I'd be tempted to remove the registry entry and see if it repopulates.

@Sikm - It's unlikely its the family tree software. Do you want to remove it? We can always back up the changes before we make it and if it's a legit program that might emulate a legacy device (e.g. Virtual Floppy Drive, WinPcap etc) we can just reinstall.
- Still post he screen print, I want to see what other info it;s showing so that I can look that up.
