Milk-V Duo S Usage of USB Type A interface

The USB functions of the DuoS USB Type A interface and Type C interface are optional and cannot be used at the same time. The default firmware is configured with the USB network port (RNDIS) function of the Type C port. If you need to switch to the USB 2.0 HOST port of the Type A port for use with USB flash drives and other devices, you need to execute the following command:

ln -sf /mnt/system/usb-host.sh /mnt/system/usb.sh
sync

Then execute the reboot command or power on again to make it take effect.

For example, after connecting a USB flash drive to the USB A port, you can use ls /dev/sd* to check whether the device is detected.

Mount it to the system to view the contents of the USB flash drive (take /dev/sda1 as an example):

mkdir /mnt/udisk
mount /dev/sda1 /mnt/udisk

Check whether the contents of the /mnt/udisk directory are as expected:

ls /mnt/udisk

Command to uninstall USB flash drive:

umount /mnt/udisk

When you want to restore the USB network (RNDIS) function of the Type C port, execute:

rm /mnt/system/usb.sh
ln -sf /mnt/system/usb-rndis.sh /mnt/system/usb.sh
sync

Then execute the reboot command or power on again to make it take effect.

TIP

DuoS has an onboard Ethernet interface, so the USB network port (RNDIS) of the Type C port can be used without switching to the USB 2.0 Host function of the A port.
