#157548 - End of enumeration Responding to: ???'s previous message |
For the HID keyboard/mouse, Put a dummy packet to the interrupt IN endpoint (EP) on the initialization. Sorry, this description is not precise. "Initialization" was ambiguous, it can be taken as the start-up initialization on this context. More precisely, Put a dummy packet to the interrupt IN endpoint (EP) on the Set_Configuration handler At the start up of enumeration, host sends bus reset to the device. When the USB engine gets bus reset, it clears out the endpoint. Set_Configuration is always put on enumeration, after bus reset and before the end of enumeration. Then, Set_Configuration handler is the good place to put the dummy packet. Tsuneo |
