OK, I get it work now. The 14.04 kernel is missing the firmware for the bluetooth hardware.
I have downloaded the firmware, renamed and copied it appropriately and now bluetooth is working: wget http://wielki.tk/vostro/debs/bt-bcm43142-onereic_0.0+20111116somerville2_amd64.deb dpkg-deb -x bt-bcm43142-onereic_0.0+20111116somerville2_amd64.deb bt-bcm43142 sudo cp bt-bcm43142/lib/firmware/BCM43142A0_001.001.011.0028.0036.hcd /lib/firmware/fw-105b_e065.hcd sudo rmmod btusb sudo modprobe btusb -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1264311 Title: BCM43142 bluetooth adapter not finding any bluetooth devices Status in “bluez” package in Ubuntu: Confirmed Bug description: On my officially Ubuntu-certified Lenovo B590 laptop the BCM43142 bluetooth adapter is not working. I have two further bluetooth devices placed closely to the laptop, non-paired and each being able to discover the other respectively. None of them is able to discover the laptop, nor does 'hcitool scan' on the laptop find any devices. It does not give any errors though.
