本文主要是介绍嵌入式 如何查看USB设备信息VID PID，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
Linux下查看USB设备的VID、PID命令
cat /proc/bus/usb/devices
或
lsusb
方法一：在/etc/init.d/rcS中添加mount -t usbfs none /proc/bus/usb.
方法二：在shell中输入mount -t usbfs /proc/bus/usb /proc/bus/usb.
前提是在编译内核时选中usb device filesystem。
# cat /proc/bus/usb /device
