Konrad, the bluetooth device in this computer needs the firmware to even be able find devices while scanning. Jesse Sung made hex2hcd to convert the windows firmware with .hex filenames to something that can be used in Linux. Pilot6 wrote this http://askubuntu.com/a/632348/300665 as a general guide

(If it matters, I *CAN* pair and use it on another laptop with Linux and with my android smartphone. So headset itself is working well.) Here is how I try to pair: $ bluetoothctl [NEW] Controller 54:27:1E:33:4B:85 impedance [default] [bluetooth]# power on Changing power on succeeded [bluetooth]# agent on Agent registered [bluetooth]# default-agent Default agent request successful [bluetooth]# scan on Discovery started [CHG] Controller 54:27:1E:33:4B:85 Discovering: yes [bluetooth]# scan on I tried to put my headset in pairing mode just before and after issuing "scan on" command. It ends up with nothing - I waited for 3-5 minutes. For example, my smartphone pairs with the headset within 5-15 seconds, my laptop pairs with the headset within about 30 seconds. ================================================================= Here is info $ hciconfig -a hci0: Type: Primary Bus: USB BD Address: 54:27:1E:33:4B:85 ACL MTU: 1021:8 SCO MTU: 64:1 UP RUNNING PSCAN ISCAN RX bytes:4475 acl:0 sco:0 events:565 errors:0 TX bytes:7214 acl:0 sco:0 commands:487 errors:0 Features: 0xbf 0xfe 0xcf 0xfe 0xdb 0xff 0x7b 0x87 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH SNIFF Link mode: SLAVE ACCEPT Name: 'impedance' Class: 0x1c0104 Service Classes: Rendering, Capturing, Object Transfer Device Class: Computer, Desktop workstation HCI Version: 4.0 (0x6) Revision: 0x1000 LMP Version: 4.0 (0x6) Subversion: 0x220e Manufacturer: Broadcom Corporation (15) ================================================================= rfkill list 0: hci0: Bluetooth Soft blocked: no Hard blocked: no ================================================================= Bluez packages installed: $ dpkg -l | grep bluez ii bluez ii bluez-btsco ii bluez-cups ii bluez-hcidump ii bluez-obexd ii bluez-tools ii libkf5bluezqt-data ii libkf5bluezqt6:amd64 ii qml-module-org-kde-bluezqt:amd64 ================================================================= $ dmesg | grep -i blue [ 4.632406] Bluetooth: Core ver 2.21 [ 4.632414] Bluetooth: HCI device and connection manager initialized [ 4.632416] Bluetooth: HCI socket layer initialized [ 4.632417] Bluetooth: L2CAP socket layer initialized [ 4.632420] Bluetooth: SCO socket layer initialized [ 4.644619] Bluetooth: hci0: BCM: chip id 63 [ 4.660554] Bluetooth: hci0: impedance [ 4.661552] Bluetooth: hci0: BCM20702A1 (001.002.014) build 0000 [ 4.661798] bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0b05-17cf.hcd failed with error -2 [ 4.661799] Bluetooth: hci0: BCM: Patch brcm/BCM20702A1-0b05-17cf.hcd not found [ 15.061603] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 15.061604] Bluetooth: BNEP filters: protocol multicast [ 15.061606] Bluetooth: BNEP socket layer initialized [ 48.001553] Bluetooth: RFCOMM TTY layer initialized [ 48.001558] Bluetooth: RFCOMM socket layer initialized [ 48.001562] Bluetooth: RFCOMM ver 1.11 [ 615.404052] Modules linked in: rfcomm pci_stub vboxpci(OE) vboxnetadp(OE) vboxnetflt(OE) vboxdrv(OE) xt_CHECKSUM iptable_mangle ipt_MASQUERADE nf_nat_masquerade_ipv4 iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conntrack rpcsec_gss_krb5 nfnetlink_queue nfsv4 nfnetlink xt_tcpudp bridge xt_NFQUEUE nfs xt_owner iptable_filter fscache cmac bnep binfmt_misc nls_iso8859_1 intel_rapl edac_core x86_pkg_temp_thermal coretemp btrfs xor snd_hda_codec_hdmi eeepc_wmi asus_wmi sparse_keymap video mxm_wmi raid6_pq btusb btrtl btbcm btintel bluetooth kvm_intel kvm irqbypass crct10dif_pclmul crc32_pclmul ghash_clmulni_intel aesni_intel aes_x86_64 lrw glue_helper ablk_helper cryptd intel_cstate input_leds intel_rapl_perf 8021q garp mrp stp serio_raw llc b43 mac80211 snd_hda_codec_realtek snd_hda_codec_generic ProblemType: Bug DistroRelease: Ubuntu 16.10 Package: bluez 5.41-0ubuntu3 ProcVersionSignature: Ubuntu 4.8.0-32.34-generic 4.8.11 Uname: Linux 4.8.0-32-generic x86_64 NonfreeKernelModules: nvidia_uvm nvidia_drm nvidia_modeset nvidia ApportVersion: 2.20.3-0ubuntu8.2 Architecture: amd64 CurrentDesktop: KDE Date: Sat Jan 7 22:36:22 2017 InstallationDate: Installed on 2014-07-05 (917 days ago) InstallationMedia: Kubuntu 14.04 LTS "Trusty Tahr" -
