$ lsusb
$ Bus 003 Device 005: ID 0bda:4853 Realtek Semiconductor Corp. Bluetooth Radio
2. 在 btusb.c 中修改/添加您的 USB 设备
/* Realtek 8852BE Bluetooth devices */
{ USB_DEVICE(0x0bda, 0x4853), .driver_info = BTUSB_REALTEK |
BTUSB_WIDEBAND_SPEECH },
// USB_DEVICE(0x____ , 0x____) is your ID name which shows in lsusb command
3.保存并构建
#Turn off your Security Boot in BIOS
make
sudo make install
reboot
