i'm using reference design for USB keyboard cap sense with this device, that's ok until i want use the demo for a keyboard emulation, but i found a issue to drive leds like caps lock, scroll lock etc.

I need to know exactly how to set the configuration to receive the leds report from host, with a usb sniffer on host i see no report sended to keyboard, so i suppose something on USB descriptor is wrong and no leds report are sended to keyboard.

can anyone help me to set USB wizard descriptor & co for this ?

Thanks in advance,

 You have to set the report descriptor correctly and should make the direction as OUT.
