libusb - Libusb on Ubuntu

Question

I use libusb to make a program to read data from USB devices on ubuntu 11:04. Why, when multiple programs to read data from usb, only a new program activation is executed while the remaining programs are not continued implementation.

Answer 1

可能是因为每个程序都试图声明设备接口（类似于程序打开和锁定文件，以便其他进程无法同时编辑文件）。
