how fix problem?

this problem exists because atheros re-used chip vid , pid.

see bug report

as workaround can patch btusb.c module , change form ath3k rome.

i've built dkms package fix issue , uploaded ppa.

https://launchpad.net/~hanipouspilot/+archive/ubuntu/bluetooth/+files/btusb-lp1542743-dkms_0.1_all.deb

install deb , reboot. should fix issue.
