Step1
通过 lsusb 指令查看USB设备的 Vendor ID 和 Product ID
lsusb
Bus 001 Device 034: ID 0483:374b STMicroelectionics ST-LINK/V2.1
Vendor ID: 0483
Product ID: 374b
Step2
在 /etc/udev/rules.d 文件夹中创建 80-usb.rules 并写入如下内容(将Step1中记录的ID分别写入):
# Copy this file to /etc/udev/rules.d/
# If rules fail to reload automatically, you can refresh udev rules
# with the command "udevadm control --reload"
ACTION!="add|change", GOTO="selfdefine_rules_end"
# Please keep this list sorted by VID:PID
# STLINK-V2.1
ATTRS{idVendor}=="0483", ATTRS{idProduct}=="374b", MODE="660", GROUP="plugdev", TAG+="uaccess"
LABEL="selfdefine_rules_end"
Step3
执行 sudo udevadm control --reload 指令
Step4
拔插你的USB设备,默认用户状态下也可以操作该USB设备
