I have filtered the hid to avoid it being recognized as a mouse，But still can't mount successfully

static const struct hid_device_id hid_ignore_list[]

static const struct hid_device_id hid_mouse_ignore_list[]

[Zhiming_Liu]

Can you confirm the driver has been add to kernel?

You need add configs to automotive_addition_defconfig 

[MickyHe]

The first step is to mount the hub of the usb touch screen successfully
The second step is to mount the usb touch screen driver。

The hub was unsuccessful, it has already exited, so it failed to load the usb touch screen。

[MickyHe]

I modified defconfig，The path is as follows，And shield the usbhid driver，but not loaded usbtouchscreen。This usb touch screen has a hub, which has been exited early。
