I've booted off Fedora 26 USB thumbdrive, to discover that everything works (dualband WiFi, BT, devices can be discovered), so the hardware is not faulty. I've converted Linux' drivers/bluetooth/ath3k.c to libusb to obtain rom_version and ref_clock of my card, so I know which firmware files I need (just in case): # ./a.out get_state -> 1, state = 0xce get_version -> 20, rom_version = 0x11020000, clock value = 40 I've then rebooted back into FreeBSD. Apparently, this AR3012 hardware if very fragile, it can be easily left in confused state and won't accept further commands, "usbconfig reset" does not help. To avoid this, it is better run ./ath3kfw as root, after powercycling machine (to reset the card). This got me further: ath3kfw: opening dev 2.2 main: state=0x0e ROM version: 285343744, build version: 155, ram version: 155, ref clock=1 ath3k_init_firmware: loading ath3k-1.fw ath3k_load_fwfile: file=/home/danfe/ath3k/share/firmware/ath3k/ath3k-1.fw, size=246804 ath3k_load_fwfile: transferring 20 bytes, offset 4096 LIBUSB_FUNCTION: libusb_bulk_transfer enter LIBUSB_FUNCTION: libusb_submit_transfer enter LIBUSB_FUNCTION: libusb_submit_transfer leave 0 LIBUSB_FUNCTION: libusb_handle_events_timeout_completed enter LIBUSB_FUNCTION: libusb10_handle_events_sub enter LIBUSB_FUNCTION: libusb_handle_events_timeout_completed exit LIBUSB_FUNCTION: libusb_handle_events_timeout_completed enter LIBUSB_FUNCTION: libusb10_handle_events_sub enter LIBUSB_TRANSFER: sync I/O done LIBUSB_FUNCTION: libusb_handle_events_timeout_completed exit LIBUSB_FUNCTION: libusb_bulk_transfer leave ath3k_load_fwfile: transferring 4116 bytes, offset 4096 ... ath3k_load_fwfile: transferring 8212 bytes, offset 4096 ... ath3k_load_fwfile: transferring 12308 bytes, offset 4096 ... ...

Timeout ./danfe P.S. Fedora is amazing (just as Ubuntu) on this laptop: everything works, WMI multimedia keys, LCD brightness control, mic/speaker mute buttons, WiFi and Bluetooth. Under FreeBSD, only WiFi works from this list. :-(
