谢谢两位 ，搞定啦。

lichee/linux-5.4/drivers/hid/usbhid/Kconfig

menu "USB HID Boot Protocol drivers"
        depends on USB!=n && USB_HID!=y && EXPERT

config USB_KBD
        tristate "USB HIDBP Keyboard (simple Boot) support"
        depends on USB && INPUT
        ---help---
          Say Y here only if you are absolutely sure that you don't want
          to use the generic HID driver for your USB keyboard and prefer
          to use the keyboard in its limited Boot Protocol mode instead.

          This is almost certainly not what you want.  This is mostly
          useful for embedded applications or simple keyboards.

          To compile this driver as a module, choose M here: the
          module will be called usbkbd.

          If even remotely unsure, say N.

config USB_MOUSE
        tristate "USB HIDBP Mouse (simple Boot) support"
        depends on USB && INPUT
        ---help---
          Say Y here only if you are absolutely sure that you don't want
          to use the generic HID driver for your USB mouse and prefer
          to use the mouse in its limited Boot Protocol mode instead.

          This is almost certainly not what you want.  This is mostly
          useful for embedded applications or simple mice.

          To compile this driver as a module, choose M here: the
          module will be called usbmouse.

神奇了，一定要屏蔽 USB_HID 才能打开 USB_KBD和 USB_MOUSE

难道是互斥的吗？

@cube_work 配置USB HID要在input里打开input设备，HID是一个较低层的接口，上层还需要input的支持，或者直接打开USB KEYBOARD这样的，直接提过支持
