      各种方法都试过了，轮毂控制版通过和笔记本连接的usb转串口打不开，底盘不工作，有人知道怎么设置吗？

        @毛哥成山轮胎机油保养 没绑定前可以用吗？我之前在22上也遇到过一次问题。

        终端输入

        sudo dmesg | grep brltty

        如果你能收到这样的结果

        [ 7033.078452] usb 1-13: usbfs: interface 0 claimed by ch341 while 'brltty' sets config #1

        问题就很明显了，是驱动占用问题

        sudo apt remove brltty

        重新插拔一下即可

            |__ Port 13: Dev 7, If 0, Class=Vendor Specific Class, Driver=ch341, 12M

        ls /dev/ttyUSB0 
/dev/ttyUSB0

          @小鱼 鱼总，我心中的大神，按你说的方法，底盘终于在humble又重新启动了，收徒弟不？😄

          sudo apt remove brltty

          用这个命令卸载了brltty

          ATTRS{waiting_for_supplier}=="0"

          sudo gedit /etc/udev/rules.d/usb.rules

          KERNELS=="3-1:1.0", MODE:="0777", GROUP:="dialout", SYMLINK+="ttyTHS1"

          保存usb.rules重启笔记本就可以打开端口正常运行了。下面是运行效果

          m@jt:~$ ros2 launch rikibot_foc_driver rikibot_foc_driver.launch.py

          绑定usb端口用的这个网址的方法
          ubuntu下绑定USB设备的串口名称

          *不解决端口占用前 ls /dev/ttyUSB0 显示没有这个usb，卸载brltty才能显示出正常usb0信息
          水太深了，有点不适应。

              @小鱼 弄了好几天，就是不成功，按网上的绑定方法都试了一遍，ttyUSB0 根本就没有 有ttyS0，我还以为ubuntu22.04把usb的名字给改了呢？这水也太深了

                @毛哥成山轮胎机油保养 被这个brltty坑的人不少呀
                ubuntu22.04的 brltty 导致 USB 转串口连接失败
