USB/IP: USB device sharing over IP

make menuconfig配置：

Device Drivers -> Staging drivers -> USB/IP support
Device Drivers -> Staging drivers -> USB/IP support -> Host driver

如果還有作為客戶端的需要，繼續做以下配置：

Device Drivers -> Staging drivers -> USB/IP support -> VHCI hcd

USB/IP userspace 應用程序編譯

cd drivers/staging/usbip/userspace
./autogen.sh （Generate configuration scripts.）
./configure --target=arm-none-linux-gnueabi --host=arm-none-linux-gnueabi --prefix=/home/huangp/work/month25_01/usbip/tmp_MT33 (指定output路徑)CC=/opt/arm/4.3.3/arm-2009q1/bin/arm-none-linux-gnueabi-gcc CPATH=/usr/include/sysfs/ --with-usbids-dir=/tmp/tmp_MT33/share （默認路徑下缺少ids文件，所以手動配置）
make
make install
