Created attachment 254261 [details] lsusb output I recently got Lenovo yoga 510. I installed linux, but noticed that some of the device drivers are not working(mainly bluetooth). This results in inability to disable bluetooth and save power(at least according to powertop). I attach the output of lsusb and dmesg, please tell me if I need to give anything else.

Created attachment 254281 [details] powertop output This is the output from powertop, it shows that this device is using 1.5W of power, although bluetooth is disabled in settings. I don't know what else to do.
I can confirm the finding. I added lots of BT_INFO calls to the driver to trace the proper initialization and firmware loading (no errors). Still, no device is shown by "hcitool dev". I don't know the BT drivers very well, but I wonder why the device appears in the "blacklist" vector? It seems that all those devices need some extra firmware? It would be great if this could be fixed. I have two machines with the device, ready to test fixes as needed. I haven't figured out how the driver goes from being loaded to actually create the hci0 device, else I could report more details.
