Main problem is my notebook is not able to search or detect this device. I have installed the latest bluetooth driver "sp47022.exe" from hp site. I am facing this problem with the headphone only, rest of my devices like mobile phone, wifi internet are connecting nicely. Headphone is also connecting to other notebooks without any problem, so there is no qus of any of the device being out of order.
My OS is "Microsoft Windows 7 Professional (32-bit)".
