The NRF_DRV_USBD_TRANSFER_IN is a helper macro for declaring IN transfer description in "normal transfer mode". The tx_buff here is simple the buffer that is to be transferred using the USB peripheral.

The generic USBD HID uses the APP_USBD_HID_MOUSE_REPORT_DSC_BUTTON descriptor for a HID generic class. I'm still not sure what you mean about "relation" between these though.

Hi,Simonr：

About the buffer: the buffer what I refer to is p_rep_buff->p_buff In the function NRF_DRV_USBD_TRANSFER_IN() as the picture below:

As I said before, I want to find out the relations between the Hid Decriptor Table and the buffer mentioned just above.

I'm sorry, but I can't find any references to the buffer you mention. Please be more precise, as I'm not able to understand which buffer you're referring to.

Best regards,
Simon

HI,Simonr:

1.Thank you for your replay very much!

2.About the ralation,I means the USBD_HID_DESCRIPTOR as the Descriptor table :

and

I just want to know in those two pictures,what is the relations btween the table and the buffer filled by the function.

1. Please check out this tutorial on USB HID descriptors. There are also multiple cases here on DevZone regarding HID descriptors.

2. Again, what do you mean by "relations between the descriptor and data_buffered"?

3. No, as I said in my last reply, the USB HID Generic example do not use the receiver and transmitter functions used in the BLE HID mouse application.

Simon

Hi,Simonr:

Sorry! Maybe I could't express my opinion clearly. Now I learn to make a wire mouse with the usbd_hid_generic example.

and then the mouse is OK. But now I want to make another USBD_HID_CUSTOM to transfer extra data from PC to the mouse, So........

1.how to setup the desciptor?

2.what is relations between the descroptor and data_buffered ?

3.Is the USBD HID Custom receiver_Function and tansmit_Function in the USBD_HID mouse examples?

1. I'm sorry, but I'm struggling to understand this question. What do you mean about the "relations" between the descriptor and data buffers? What kind of custom communication do you plan on adding? Do you mean adding I.E. additional buttons to your mouse?

2. The HID mouse application uses BLE and the Bluetooth HID Service to communicate with a central device like a PC or smart phone, while the USB HID Generic example shows you how to handle a HID mouse like device using the HID generic protocol and requires a USB connection for communication, so no these examples do not use the same receiver and transmitter functions.
