I am running the 20.10 image on the rockpro64. These 3 lines are written to the system log every second or so
Oct 20 22:07:30 rock64 kernel: busb rockchip_usb2phy_otg_sm_work b_idle otg sm work 1
Oct 20 22:07:30 rock64 kernel: busb HOST = 0,VBUS_EN=0,vbus_attached=1
Oct 20 22:07:30 rock64 kernel: busb vbus_attach rphy->chg_state = 5
I am getting these messages permanently, no matter if there is something connected to an USB port or not. Any idea what causes this?
