Get data for USB HID Keyboard's LED via Class Request 0x09 (Set Report)?

Curiously the data stage is already handled before

static usbd_respond cdc_control(usbd_device *dev, usbd_ctlreq *req, usbd_rqc_callback *callback)

is even called! I did not expect that. So, my code is much simpler even:

if((req->bmRequestType & (USB_REQ_TYPE|USB_REQ_RECIPIENT)) == (USB_REQ_CLASS|USB_REQ_INTERFACE))
   {
   switch(req->bRequest)
      {
      case USB_HID_SETREPORT:          // 0x09
           ReportType = req->wValue >> 8;         // 2=Output report, 3=Feature report
           ReportID   = req->wValue &0xFF;
           // ToDo: check the above two values first...
           HidKbLEDs = ((uint8_t *)dev->status.data_ptr)[0];
           return usbd_ack; 

Let me know if this is indeed correct.

Hi
Yes, that's correct.
