USB 2 port not available

[mitu]

Hello,

 

I have installed the Armbian 26.2 minimal IOT image based on Debian 13 Trixie - with the 6.18.x kernel - and I noticed the USB2 port (the single, vertical port next to the Ethernet port) is not working. Is this a limitation of the mainstream kernel (6.18.x) - i.e. does this work only with the vendor kernel (6.1.x) ? NB: I upgraded to 6.19 using the 'edge' kernel, but I'm seeing the same behavior.

 

Here's the armbianmonitor outpur - https://paste.armbian.com/raw/udefojuxuk

I encountered the same issue. When I used the Orange Pi 3B image based on the 6.18 kernel, USB was not available, but when using the 6.1 vendor image, USB worked.

@tim zeng sure, but that's not - directly - related, since the Orange PI5 and the Orange Pi3 are different SOCs/SBCs. The only common trait is the poor SW support offered by the vendor.

I have also encountered this using Orange pi 5 and latest Armbian updated as of today. That the "standing" USB port does not work also means that the  USB-C port doesn't work -- they are electrically connected.

 

So  Mitu's question is also mine:  Is this a limitation of the mainstream kernel (6.18.x) - i.e. does this work only with the vendor kernel (6.1.x)?

In mainline kernel 6.18 or above, the USB 2.0 port (and USB-C port) is configured as device mode. You can use following cmd to change to host mode to connect other USB devices, but you need to do it again after reboot.

sudo bash -c "echo host > /sys/kernel/debug/usb/fc000000.usb/mode"

It could be done by dtb overlay but there is no one available now.

The upstream default seems to be "otg" to allow users in userspace to change the usb port behavior.

Try this and use armbian-add-overlay

 

/dts-v1/;
/plugin/;

/ {
	fragment@0 {
		target = <&usb_host0_xhci>;

		__overlay__ {
			dr_mode = "host";
		};
	};
};
