SetEPTxCount(ENDP2, count）
If count is less than or equal to the COUNT specified in the report description, the USB input device can send data, but the HID Complaint Device cannot obtain data when requesting data from the USB input device layer.
First select:
In BUS Hound:
If count <=report Count Size: then the results are as follows:
On the contrary: when count >report Count Size: as follows:
The above one is that the HID Complaint Device cannot request data from the USB input device, while the following one can request data!
