1. 安装xboxdrv和joystick
sudo apt install xboxdrv
sudo apt install joystick
2. 将usb无线接收器插入，查看设备信息
cat /proc/bus/input/devices
输出如下信息说明系统已经识别到了xbox的接收器
I: Bus=0003 Vendor=045e Product=0719 Version=0100
N: Name="Xbox 360 Wireless Receiver"
P: Phys=
S: Sysfs=/devices/virtual/input/input28
U: Uniq=
H: Handlers=event28 js3
B: PROP=0
B: EV=b
B: KEY=f 0 0 0 0 0 0 7fdb000000000000 0 0 0 0
B: ABS=1b

3. 编译xow
Xow是一个非官方的Linux版本Xbox one手柄无线适配器驱动，其底层基于libusb进行工作，通过Wifi与游戏手柄进行连接，其使用MT76xx的Wifi chip；
3.1 下载xow源码
git clonet https://github.com/medusalix/xow.git
3.2 安装依赖
audo apt install curl libusb-1.0-0-dev cabextract
3.3 编译
cd xow
make BUILD=RELEASE
sudo make install
3.4 Download the firmware for the wireless dongle:
sudo xow-get-firmware.sh
3.5 运行xow
sudo ./xow
[sudo] password for sar:

3.6 编译错误解决：
执行make BUILD=RELEASE报错：找不到uinput_setup、uinput_abs_setup的定义
报错原因：linux内核版本太低，xow不支持UINPUT_VERSION 5以下版本；
解决方法：从高版本的ubuntu中拷贝/usr/include/linux/uinput.h替换当前系统下的/usr/include/linux/uinput.h
xow驱动分析可以参考这篇博客：https://blog.csdn.net/YingbinLi/article/details/123268015
4. xbox手柄测试
先运行./xow，在按下xbox one手柄最前端的带x标识的圆形按键，按下按键后按键灯点亮，开始慢闪，配对成功后，按键灯常亮；
打开了一个linux终端，运行：
sudo jstest /dev/input/js4
Driver version is 2.1.0.
Joystick (Xbox One Wireless Controller) has 8 axes (X, Y, Z, Rx, Ry, Rz, Hat0X, Hat0Y)
and 11 buttons (BtnA, BtnB, BtnX, BtnY, BtnTL, BtnTR, BtnSelect, BtnStart, BtnMode, BtnThumbL, BtnThumbR).
Testing ... (interrupt to exit)
Axes: 0: 0 1: 0 2:-32767 3: 0 4: 0 5:-32767 6: 0 7: 0 Buttons: 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off 8:off 9:off 10:off

注意：在/dev/input下可能会生成js0, js1, js2, js3, js4 5个文件，可以分别使用jstest 测试一下，运行sudo jstest /dev/input/js4 后， *** 作手柄 *** 作杆查看数据是否有变化。
5. xbox手柄 *** 作数据接收与解析
