I have bought the BUA-100 dongle to use with my Plantronics Discovery 925 so that I am able to use the Discovery 925 with my Skype on my iMac, but I cannot get the two to pair. I have already paired Discovery 925 to my Nokia mobile phone, which works perfectly with the phone, but it just does not want to pair to the dongle. I have already activated the multi-point bluetooth feature on Discovery 925 - does not solve the issue. I also tried deleting the headset from my mobile phone and then pairing it 'as first device' to the Dongle - no luck. As my Mac itself obviously does not recognise the headset (there are various discussions ont this), so the only way I can use my headset with Skype is to pair it to BUA-100 dongle for which I have just paid GBP45. But even this does not seem to work. What I do: I plug the dongle into an empty USB slot in my iMac, it starts flashing blue (as far as I remember). Then I pinch the small button on the dongle, it starts flashing violet/red (or something similar) I suppose indicating pairing mode. Then I switch on my Plantronics 925, but nothing happens. Neither the dongle nor the headset shows any signs of pairing. The dongle just keeps flashing violet/red for about a minute or two, and then stops. When I select the BUA-100 as input/output in Skype's Audio preferences - I hear absolutely nothing. Mic does not work either. Has anyone experienced this? Does anyone know how to solve it? Maybe faulty equipment (my dongle came in a bit of a makeshift packaging with no instructions)? I thought maybe once I paired my headset to a phone it won't pair to anything else (ever?). Surely this cannot be right. Any help much appreciated.
