To try and find out what Device this is or was.
Right Click on these Devices showing the Warning and select Properties.
What does it state ???
Open the Details Tab.
Scroll down to Hardware Ids.
Using those strings do a Google Search on the item.
OR : Post those strings.
Wondering if this could be related to a Uninstalled or Unplugged Blue Tooth Device, ... as i see some other listed Blue Tooth Radios.
Think back as to all the Blue Tooth Devices that you had previously connected but may now be unplugged.
Plug these items back in ONE at a time and see if the Device Manager clears the Blue Tooth Peripheral Device warnings.
It could even be a phone / printer or other such devices.
Otherwise :
Right Click and Uninstall / remove.
Reboot the computer or refresh the Device Manager.
When it restarts or refreshes and it shows up again then you will need to look further.
I found out it is my cell phone, which I used ages ago to transfer music files from my notebook to the phone, by bluetooth. I deleted it and the yellow questions are gone. Alas, that wasn't what was keeping me from upgrading to windows 10 but still working on that.
