When I got my Lenovo-Z50-70 I directly installed Ubuntu 14.10, the Wifi (Atheros AR9565) worked out of the box. But then I wanted to connect my bluetooth devices it never found any of them.

I looked at rfkill nothing was hard of softblocked.

According to Lenovo the BTchip is a Atheros QCWB355 but I can't find any available Linux drivers.

I also looked in my bios if there where any configurations but there was nothing relevant.

Does someone know a where I can get a driver for this or if there is an other problem?

  • I tried it and it now finds devices, the only problem still is that the devices that it finds are of type unknown so it can' t connect and it only displays its address, not its name. – Emilio1810 Apr 13 '15 at 20:55
  • What type devices are they? I remember that some devices are not yet supported by the Ubuntu bluetooth stack – Jeremy31 Apr 13 '15 at 23:14
