no mac address when usbncm used on Win10 #20

I have verify my netcard function with usb ncm on linux & win11. But on win10, net adapter created by my netcard doesn't have mac address. I have matched my card with UsbNcm Host Device driver. In BusHound serial, it can be seen that the host pc driver have asked for the mac address by string descriptor. And the device returned the right string value. I also tried to set a mac address in the device manager. The netcard will work correctly.

Can anyone tell me that why driver create a netadapter with no mac address?
