Windows 8 Upgrade - Unknown Devices

2012-11-24, 16:04 PM

Hi,

 

I have recently upgraded my Lenonvo Z580 from Windows 7 to Windows 8.

Before I upgraded, I ran the compatibility wizard and the only things it told me wouldnt be compatible is a couple of pieces of software I had installed.

 

Since the upgrade, there are a few things showing in the Device Manager under Other Devices that are unknown. I have installed everything from the Drivers section on the Lenovo site but they are still showing.

 

Bluetooth Peripheral Device

5 x Unknown Devices

USB2.0-CRW

 

Im guessing the last one might be my SD Card Reader as I have just tried to use it and it didnt work. This is what prompted me to check the Device Manager in the first place.

 

Can anyone help me please?

Thanks,

Harrison

Ok, a little update.

 

I have now uninstalled a piece of software that I was using called Splashtop.

This has removed the 5 Unknown Devices but the Bluetooth Peripheral Device and USB2.0-CRW are still showing.

I had similar trouble while i was in win8 for a couple of hours, i installed everything from the downloads website for the z580. My only advice is that for the energy management thingy it seems you need to install the win7 version (i didn't do it but others on here told me that's the way to go)

Wow, thanks!! :smileyvery-happy: :smileyvery-happy: :smileyvery-happy: :smileyvery-happy:

That worked for my SD Card Reader.

 

I guess now i just gotta work out what the Bluetooth Peripheral Device is and find the driver for that. I cant think what it would be as my Bluetooth is working fine.
