Damien George fa07deda9f stm32/usbd_hid_interface: Rewrite USB HID interface code. ... The previous version did not work on MCUs that only had USB device mode (compared to OTG) because of the handling of NAK. And this previous handling of NAK had a race condition where a new packet could come in before USBD_HID_SetNAK was called (since USBD_HID_ReceivePacket clears NAK as part of its operation). Furthermore, the double buffering of incoming reports was not working, only one buffer could be used at a time. This commit rewrites the HID interface code to have a single incoming buffer, and only calls USBD_HID_ReceivePacket after the user has read the incoming report (similar to how the VCP does its flow control). As such, USBD_HID_SetNAK and USBD_HID_ClearNAK are no longer needed. API functionality from the user's point of view should be unchanged with this commit.		2019-07-25 17:42:17 +10:00
