Hi

I have issue with setting up USB Host HID on Stm32f105. It is simple circuit only 8Mhz crystal and 2 22pF caps. And USB port.

​

I did set up RCC, usb to host only, and HID interface​.

After generating code I can see that state machine is changing on inserting mouse or keyboard.

​But it never get enumerated. It stops at HOST_ENUMERATION, and never completes process and never get to APPLICATION_READY.

​

What​ can I check to solve this issue?
