How to get HID-keyboard LED status?

Posted: Wed Jan 13, 2010 10:04 pm

I have a problem with my PIC18F2550 when trying the USB-HID-Keyboard in the ex_usb_kbmouse.c example. I can't get the value of LED status, such as NUM LOCK, CAPS LOCK, etc, from PC.

How to get the value of LED status? (** value of "leds" always ZERO!)

Code:

//receive NUM LOCK, CAPS LOCK, etc LED status from PC.
//we won't do anything with it.
if (usb_kbhit(2))
{
usb_get_packet(2, &leds, 1);
}

What should I do?
Best Regards,
