MIDI + Keyboard + Serial

[ghost]

How can i do this

HID.begin(HID_KEYBOARD);

midi.registerComponent();
CompositeSerial.registerComponent();

?

[arpruss]

HID.setReportDescriptor(HID_KEYBOARD);
HID.registerComponent();
CompositeSerial.registerComponent();
USBComposite.begin();

The HID.begin() shortcut should only be used for a single-component device.

But note that at least on Win10, a composite device with MIDI and serial in it won't have the serial work.

Ок and other question How can i create custom i have test code

int main() { struct usb_bus busses; usb_init(); usb_find_busses(); usb_find_devices(); busses = usb_get_busses(); struct usb_bus bus; struct usb_device * dev = NULL; for (bus = busses; bus; bus = bus->next) { for(dev = bus->devices; dev; dev = dev->next) { if(dev->descriptor.idVendor == 0xCAFE && dev->descriptor.idProduct == 0xC002) { //Нашли первое устройство. Работаем с ним. Если нужно работать со всеми, то собираем список здесь goto found; } } }

fprintf(stderr, "Not found devices\n");
fflush(stderr);
return __LINE__;

found: ;

usb_dev_handle *ukey_handle =  usb_open(dev);
if (NULL == ukey_handle) {
  fprintf(stderr, "Error opening: %s\n", usb_strerror());
    fflush(stderr);
    return __LINE__;
}

const int endpoint_out_num = 3; //endpoint для посылки команд
const int endpoint_in_num = 2;  //endpoint для чтения ответов
//По хорошему нужно искать нужные номера endpoint в interface discriptor, но т.к. устройство у нас константное, искать не будем

need send some command on STM32

[arpruss]

I don't understand what you are trying to do. Sorry.

[ghost]

need create device HID USB KEYBOARD with custom usb functions (when i send usb_bulk_write on pc stm doing my code (playing notify sound)) i can`t change windows driver they need create custom usb with 2 endpoint const int endpoint_out_num = 3; //endpoint const int endpoint_in_num = 2; //endpoint and process input command and out command

lsusb.txt device-descriptors.hex.txt hidreport-descriptor-hex.txt

need create same devices

[arpruss]

You need to make your own plugin. Start by taking the plugin closest to what you want.

The way I write plugins is in two parts: there is a low level part in C (e.g., usb_composite_serial.c) and a high level part in C++ (e.g., USBCompositeSerial.cpp).

There is no documentation on how to do it.

[ghost]

Саn you help me with plugin? i dont know how i`ll make it self

[arpruss]

Sorry: it would take too much hand-holding. I suggest you modify an old one.

[ghost]

I don't have an old source, I'm remaking the device.

[arpruss]

I meant: take the source code for one of the plugins in this library and change it to fit your needs.

[ghost]

Well I'll try
