[ 4507.934913] usb 2-1.6: new full-speed USB device number 6 using ehci-pci[ 4508.046595] usb 2-1.6: New USB device found, idVendor=0b05, idProduct=17cb[ 4508.046599] usb 2-1.6: New USB device strings: Mfr=1, Product=2, SerialNumber=3[ 4508.046600] usb 2-1.6: Product: BCM20702A0[ 4508.046602] usb 2-1.6: Manufacturer: Broadcom Corp[ 4508.046603] usb 2-1.6: SerialNumber: 5CF3709911C3[ 4508.157541] Bluetooth: hci0: BCM: chip id 63[ 4508.158516] Bluetooth: hci0: BCM: features 0x07[ 4508.174532] Bluetooth: hci0: BCM20702A[ 4508.175548] Bluetooth: hci0: BCM20702A1 (001.002.014) build 0000[ 4508.175568] bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0b05-17cb.hcd failed with error -2[ 4508.175571] Bluetooth: hci0: BCM: Patch brcm/BCM20702A1-0b05-17cb.hcd not found

Então o seu dispositivo id é 0b05:17cb– – 0B05:17CB

e o driver deve ser esse aqui: /lib/firmware/brcm/BCM20702A1-0b05-17cb.hcd

curl -s 'https://aur.archlinux.org/cgit/aur.git/tree/filelist.txt?h=bcm20702a1-firmware' \ | grep '0B05:17CB'0B05:17CB: BCM20702A1_001.002.014.1443.1467.hex

Então o nome do arquivo é BCM20702A1_001.002.014.1443.1467.hex

Prepare para converter o driver para o linux

unzip DR_USB_BT400_1201710_Windows.zipcd Win10_USB-BT400_DRIVERS/Win10_USB-BT400_Driver_Package/64hex2hcd BCM20702A1_001.002.014.1443.1467.hex -o BCM20702A1-0b05-17cb.hcd

Copiar o driver para pasta de destino

sudo mkdir -p /lib/firmware/brcm/sudo cp BCM20702A1-0b05-17cb.hcd /lib/firmware/brcm/

Reconecte o dispositivo
