Embedded Linux system, LSUSB appears unable to initialize LIBUSB:-99 Solution "Turn"

LIBUSB is a Linux system that provides user-space access to the USB device's API to get or set USB device information from the Linux kernel. LSUSB This user space program, it is also relies on the interface API provided by LIBUSB to implement the current USB bus scanning system, so as to display the current system of USB devices.

In embedded Linux, the input LSUSB name, unable to initialize LIBUSB: 99 or no output (this is a fix to the previous bug), the main reason is that when building an embedded Linux system, The system initialization is not set up, causing the USBFS to not mount during startup. The solution is to mount the USBFS during system startup.

The following command can be done:

Mount-t Usbfs none/proc/bus/usb/

A better way to write the above command into a startup script, such as/etc/inittab or/etc/init.d/rcs.
