Hey Marcel, thx for your help! Now it works. >>Maybe the antenna is kinda wrongly calibrated, but I can't tell any >>details here. That is hardware specific. > >So you think it's not connected correctly or what means wrongly calibrated? >Perhaps I can give it a try via Virtualbox under windows ... As Virtualbox does a direct usb passthrough to the client I could install the bluetooth adapter in windows with the original broadcom bluetooth driver. Once I opened the settings there and "saved" theses, the adapter finds bluetooth devices nicely under windows AND linux. Sadly I have no idea what the broadcom driver did to "activate" the adapter. Does this make sence? For me not, but it works now. When someone is interessted in any details, I will answer any question as good as I can! Perhaps someone can integrate the vendor id and product id in the kernel source btusb.c file. The broadcom driver names the adapter 'Broadcom BCM20702 Bluetooth USB Device'. vid: 0x0489 pid: 0xE031 Ciao Thilo -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
