Thanks for your reply but I have already tried all the tips I can find from the Internet. Any idea if the following might be the problem - it is related to Qualcomm Atheros QCA61x4 Bluetooth 4.1 (driver): "Device USB\VID_0CF3&PID_E300\5&362d232&0&7 requires further installation." Is this the problem and how can I fix it?
Best,
Miikka
