Why does the USB mouse not work on STM32MP157 USB1?

[SunnyGeGe]

We have a design with a USB HOST, the schematic is shown below， And the system is Linux 4.19. We have add some configuration about USB HID as below:

 2 CONFIG_HID=y

 3 CONFIG_HID_GENERIC=y

 4 CONFIG_USB_HID=y

 5 CONFIG_USB_HIDDEV=y

 6 CONFIG_USB_KBD=y

 7 CONFIG_USB_MOUSE=y

If we connect the USB Mouse directly to J4, it does not work(The LED on the USB mouse is on), but the USB Stick works;

If we connect a USB Hub to J4, and connect the USB Mouse to the USB hub, it works.

Could you please help us to fix this issue?

Hi,

I suspect the OHCI is not enabled, but "dmesg | grep usb" does not show it. You should try "dmesg | grep -i ohci"

The wiki page

https://wiki.st.com/stm32mpu/wiki/USBH_device_tree_configuration

reports the settings for enabling ohci.

Please note that ohci is not enabled on the ST boards because both include on-board a USB hub.

[AntonioST]

By the way ... could you please provide the P/N of L3 ?

Thanks!

[SunnyGeGe]

Thank you for your reply, AntonioST!

After enabling ohci, the USB mouse works.

[SunnyGeGe]

The P/N of L3 is shown below.
