Hi,

About the USB CDC, do you mean the USB gadget of NUC970 or other VCOM converter? Can you add printk in adjust_link() function of nuc970_ether0.c and see if there's phydev->link == 0 (link down event) or status_change == true (link speed change) during your test? Thanks.

Sincerely,

Yi-An Chen
