Description

No response

Additional information

I use KMK as the firmware for the keyboard I made, but when I use a USB HUB, the Caps Lock light will not synchronize with other keyboards. The other two manufacturers' keyboards I tested can synchronize the Caps Lock light when using USB HUB. I read the definition of Class LockStatus and did some tests and found that get_last_received_report() always returns None when using USB HUB.
The above code is just a test code, please forgive me for not knowing how to trim KMK to minimize the executable code.
