Gpiochip412 enable usb power / power over ethernet?

kroon040 · December 30, 2022, 9:44pm

Hi,

I'm Using and Aruba 303h and works, but I have a question on the USB.

It has an USB port and installing some usb packages , and chips are found see log below.
Adding and usb devices, nothing happens, and I think I have to enable usb power?

I found this on GPIO, but I don't know if this is for enabling usb power? Or maybe it's for POE out, but how can I figure it out?

No access to a device atm, but there's a package called USB ctrl/control or similar, see if you can use it to control the port.

I found now this in tthe bootlog

[ 0.026087] gpio-435 (USB-power): hogged as output/high

So it should be active?

Should I do something in de /sys/class/gpio , because I don't see gpio435???

this is in the dts file


+
+	usb-power {
+		line-name = "USB-power";
+		gpios = <23 GPIO_ACTIVE_HIGH>;
+		gpio-hog;
+		output-high;
+	};
+};

412+23=435
yes, it should be active already

kroon040 · January 1, 2023, 10:28pm

OK , than it is still strange I can't see any usb devices. Tried usb stick en cp2102 uart.

Also to enable POE on my port 3 , looking at the dts file is 34, so do I need to create a gpio 412+34=446?
And how should I create it and enable it, set it in active low?

+&tlmm {
+	/*
+	 * In addition to the Pins listed below,
+	 * the following GPIOs have "features":
+	 * 39 - out - active low to force HW reset
+	 * 32 - out - active low to reset TPM
+	 * 43 - out - active low to reset BLE radio
+	 * 41 - out - pulse to set warm reset status
+	 * 34 - out - active low to enable PSE port
+	 * 22 - in  - active low when 802.3at powered
+	 * 29 - in  - active high when DC powered
+	 * 40 - in  - active low when reset due to cold HW reset
+	 * 30 - in  - active low when USB overcurrent detected
+	 * 35 - in  - interrupt line for power monitor chip
+	 * 31 - in  - active low when PSE port active

Please see https://openwrt.org/docs/techref/hardware/port.gpio#software

kroon040 · January 2, 2023, 5:43pm

Thx, the POE now works, only USB is still not working . Any idea how I can fix this?

AndrewZ · January 2, 2023, 7:54pm

Do you have power present on USB connector?
Do you see your device(s) in cat /sys/kernel/debug/usb/devices output ?

kroon040 · January 2, 2023, 8:18pm

If I use and usb tester, it gives 5v.

I only see the the internal usb host controller???

you're probably missing USB2 support
check/load kmod-usb2 kmod-usb-ehci
