"FAIL, Update_USB_QDLoader_Port, No right port!" when flashing to latest firmware

Hi there,

I’m getting an error “FAIL, Update_USB_QDLoader_Port, No right port!” when I try and flash my RM500Q-GL to RM500QGLABR11A05M4G_01.001.01.001. Could you advise? As far as I understand it I need to use the USB DM com port which I am finding by checking the com port list in device manager. Per QFlash5.5 documentation, I am using a baud rate of 460800
