USBD keyboard doesn't receive status led change. (Capslock, Numlock ...)

[Steven Cho]

Hi Everybody,

I am working on USBD keyboard.

I used USBD example for implementation.

I changed mouse profile to keyboard profile.

And it's recognized well without problem in device manager.

But it doesn't get status change from PC. (capslock, numlock, ...)

When I test it using "usbd_hid_composite" example it receive well.  But that example is too complex to extend devices.

So I choosed USBD example.

SDK version: 17.0.2

Used example: USBD

Changes : mouse to keyboard

Hi Steven

Please check out Dmitry's replies in this case, where it is explained how the HID specification treats various output reports. Please also check out this thread for more information on how to handle endpoint data transfers over USBD.

Best regards,
