这个错误表明 ADB 无法启动守护进程（adb daemon），主要原因是 USB 设备访问权限不足（Access denied (insufficient permissions)）。

检查 USB 设备是否被识别
lsusb
Bus 001 Device 009: ID 2a45:0c01 Meizu Corp. MEIZU 18s Pro # 重点是 2a45:0c01 -
创建 udev 规则（永久解决权限问题）
18是自定义名字，只要和rules.d文件夹下的rules不同明即可
sudo gedit /etc/udev/rules.d/18-android.rules
xxx-android.rules的内容如下，将上面得到的 2a45:0c01 放到下面的ATTR中
SUBSYSTEM=="usb", ATTR{idVendor}=="2a45", ATTR{0c01}=="0c01", MODE="0666", GROUP="plugdev"
保存后运行
sudo chmod a+r /etc/udev/rules.d/18-android.rules # 确保规则可读
sudo udevadm control --reload-rules # 重新加载规则
sudo udevadm trigger # 立即生效 -
将当前用户加入 plugdev 组
sudo usermod -aG plugdev $USER -
拔掉数据线重新插上，然后手机上弹窗允许USB调试即可。
