An unknown device appears

In device manager is showing an unknown device. And I think it is new, because I never seen that before.

It is similar to this topic :
Unknown Device

I think the problem is the : ROOT\LEGACY_CPUZ132\0000


I do not know that I could be. I already checked the pc with ESET and nothing. One solution I can think of is to reinstall everything again


Anyone can help me ?

And you can account for every device connected to the PC? Can you please check in your BIOS and see if Legacy USB is enabled? I've got to go offline now but if you could just check that in the BIOS in the meantime.

Please do this:

In Device Manager, right click on the unknown device > Properties > Details Tab > Drop Down Box > Hardware Id's

You may see something like this:
An unknown device appears-capture2.jpg

The 4 digit number after VEN, and the 4 digit number after DEV is what you need.

Then go here:
PCI Vendor and Device Lists

Enter the VEN number in the appropriate box and search to find the manufacturer.
Enter the DEV number and search to find the type of device.

If you get something that looks like this:
An unknown device appears-capture1.jpg

Then you have a USB device. That is a different animal. Post the VID and PID numbers in that case.

Tell us what you find.

No sorry, what I meant was do you have a device connected to your PC that has no drivers/isn't working properly.

Can you check your BIOS to see if Legacy USB is enabled, and please follow TVeblen's steps above and report back.

TVeblen : there is nothing in the unknown device. Other devices have the hardware Ids, but this does not

Boozad : I will try to review it. Where is ? A small guide

I'll have to have a look at your motherboard manual, I've just landed at work so it will be some time before I get back to you on that.
