I bought a pair of headphones (Philips SHB7000). They work with my phone and Nexus.
However, when I tried to connect them to my Acer Aspire V5 they got connected but after one second they disconnected. I tried again, and the same happened. I started to troubleshoot and updated the BT driver (though it was updated) but nothing happened. Eventually I uninstalled the BT-device (Atheros).
I downloaded the latest driver (again) från Acer website and reinstalled it.
But now the BT device is no longer visible in the device manager or the start up screen...
I have uninstalled and reinstalled the correct (acccordning to acer support download) driver. No errors during installation. But I cannot get the unknown USB device to understand that it's a BT device. Even though it's an unknown device the computer doesn't promt this at start up. If I try to search for "new devices" it's not found.
BT is forever lost on my Acer!
