1. How to config kernel for HID in S605-32 BSP?
   • make menuconfig
     • USB support–>Support for Host-side USB–>OHCI HCD support–>Nuvoton W55FA93 OHCI support–>USB OHCI type(USB host-like Port 2)
     • HID Devices–>/dev/hidraw raw HID device support(enable)
     • Multimedia support–>Video capture adapters–>V4L USB devices(disable)
   • Save config file and ./build sd or spi
2. Refer to hidusb.tar.xz, GAS senaor sample code
3. How to get USB(HID) device information?
