STM32: read data in device sent by host over USB HID
In an STM32CubeIDE USB HID project for an STM32F103C8 board I can send data from the device to the host using the `USBD_HID_SendReport()` function, like so:

```
USBD_HID_SendReport(&hUsbDeviceFS, (uint8_t*)&hid_report,sizeof(hid_report));
```

How can I read data in the device sent over USB HID by the host?

In particular, I'd like to send arbitrary data (say, 1024 bytes) from the host using something like `hid_write()` from libusb's [hidapi](https://github.com/libusb/hidapi) and then read it in the STM32 device.  
How can I do that?
