下面是usb键盘的初始化：

#define DRIVER_DESC "USB HID core driver"

static int __init hid_init(void)
{
   int retval = -ENOMEM;

   retval = usbhid_quirks_init(quirks_param);
   if (retval)
       goto usbhid_quirks_init_fail;
   retval = usb_register(&hid_driver);
   if (retval)
       goto usb_register_fail;
   printk(KERN_INFO KBUILD_MODNAME ": " DRIVER_DESC "\n");

   return 0;
usb_register_fail:
   usbhid_quirks_exit();
usbhid_quirks_init_fail:
   return retval;
}
