Previously, I use STM32F205 (M3) USB HID, out endpoint (Interrupt type).

​Now I'm developing ST M0 (STM32F070) and I have a problem as follow

​By using STM32F070, HID USB, and then enpoint 5, Out Interrupt should be use.

​But, Device send only STALL packet as attached pic ( I hope to send ACK packet)

I don't know why device can't send ACK packet.

perhaps, ST M0 seems like not to be support USB HID, Endpoint Out interrupt . right?

Please give advice.
