| Abstract: | Linux operating system due to its source open,with cutting characteristics in embedded systems is increasingly applied,and USB interface on the embedded system application also is very extensive,now the embedded system hardware platform is most based on ARM processor.Standard is introduced based on the ARM platform kernel Linux 2.6,embedded USB host device driver development realization.From the USB device driver of the development process,we introduce the USB interface of the general principle and USB communication general process,then USB driver skeleton was analyzed,and finally gives a concrete realization of key driver code. |
