Hi,

first of all, having 2 configurations won't solve your problem. As mentioned in the training, configurations are used for different "power modes" of the USB device. What you need is to have 1 device descriptor, 1 configuration descriptor and 2 interface descriptors (assuming you are going the "composite device way").

If you are using ST Middleware, you need to change interface descriptors in usbd_hid.c file, and also other functions, e. g. for reporting and enumeration of the device.

Hi @VDodi.1 ,

yes, this is possible either with multiple HID Top-level collections (if you mean under the term "interface" the logical USB interface) or with a composite device (multiple USB interfaces, but still one device = one HW interface).

Hi,

if you are starting with USB, I would recommend you some tutorials, e. g. this. There you can learn the general principles as well as how to send data to the host device. Or check the examples @Piranha posted.

If you have some specific question about sending the data, please share more details.

BR,
