Design of USB Interface Driver for WSNs Node Tester Based on Embedded Linux

Based on the analysis of the design of USB peripheral driver program under embedded Linux and considering of the hardware characteristics of USB interface of the Portable WSNs Node Tester, the USB interface drive program for the Portable WSNs Node Tester based on the embedded Linux was designed by the way of kernel module. The WSNs Node connected the Tester through the USB interface, information transmission between the Tester and the WSNs Node was successfully realized.
