Bluetooth USB Dongle Plug-in Not recognised

Hi,
My PC Details are:
Lenovo-Q200-Desktop
Windows 10 - 32bit - Enterprise - Evalution edition
Intel Core2 Duo E4600 2.4GHz

Recently I have installed Windows 10 Enterprise Evalution edition in my PC. The Bluetooth USB dongle, when plugged-in doesn't create 1)the notification sound 2)Dongle's LED not glowing 3)drivers not installed by win10 4)no errors displayed 5)no entries added into device manager.

All the above used to happen when I plugged into PC in another Vista partition.

I noticed that under This-PC, Only the partitions are listed as C,D etc. There are no Removeable Disks segment like in Vista

I have 5 USB ports in my PC. When I connect an external HDD, a drive letter is added and am able to use the HDD. In another USB, I have permanently added USB-Receiver for my keyboard and mouse which is sensed by windows-10. If I use the same USB port for my bluetooth dongle, no reaction from the PC.
Any ideas?


Thanks in advance
