I built openwrt v22.03.0-rc5 for my gl-ar300m16 and it works except for the power to the USB port. It seems like mainline openwrt needs a patch to connect the USB GPIO power supply to the USB port for the GL-AR300M16 target? Searching these forums i see there was a similar issue a few years ago between gl-inet firmware 2.26 and 2.27 [USB devices not recognized - #8 by patchmaster](https://forum.gl-inet.com/t/usb-devices-not-recognized/3386/8) I suspect the same patch is required for mainline openwrt? ---

I didn’t test openwrt 22.03 on AR300M16. But if the USB is powered off by default, a simple solution is to enable it in /etc/rc.local Just write a command to enable the USB, e.g. writing 0 or 1 to the gpio control. ---

Yes i tried that but couldn’t export GPIO 2 (i suspect with the new 5x kernel its not actually gpio 2 but called something else) Anyway i managed to get it to work by creating this patch: ```auto diff --git a/target/linux/ath79/dts/qca9531_glinet_gl-ar300m.dtsi b/target/linux/ath79/dts/qca9531_glinet_gl-ar300m.dtsi index d64ffa7115..5aaa149940 100644 --- a/target/linux/ath79/dts/qca9531_glinet_gl-ar300m.dtsi +++ b/target/linux/ath79/dts/qca9531_glinet_gl-ar300m.dtsi @@ -43,8 +43,7 @@ regulator-name = "usb_vbus"; regulator-min-microvolt = <5000000>; regulator-max-microvolt = <5000000>; - gpio = <&gpio 2 GPIO_ACTIVE_HIGH>; - enable-active-high; + gpio = <&gpio 2 GPIO_ACTIVE_LOW>; }; leds { ``` ---

Did you already mentioned this on github for openwrt, so this bug can be fixed in the next bulids? ---

No, i didnt, you will need to submit a patch to openwrt mainline ---

Could you please post the link here to your corresponding pull-request as soon as created? → I urgent need a fixed firmware and would be happy, when this bug is fixed in the next openwrt release (\>22.03.2). Thanks in advance! ---

Problem finally solved. Pls check the patch. It is due to a driver issue actually. > > > glinet forum users reported the problem at > https://forum.gl-inet.com/t/gl-ar300…m16-openwrt-22-03-0-rc5-usb-port-power-off-by-default/23199 > > The current code uses the regulator framework to control the USB power supply. Although usb0 described in DTS refers to the regulator by vbus-supply, but there is no code related to regulator implemented in the USB driver of QCA953X, so the USB of the device cannot work. > > Under the regulator framework, adding the regulator-always-on attribute fixes this problem, but it means that USB power will not be able to be turned off. Since we need to control the USB power supply in user space, I didn't find any other better way under the regulator framework of Linux, so I directly export gpio. > > Signed-off-by: gl-luochongjun \ > > Thanks for your contribution to OpenWrt! > > To help keep the codebase consistent and readable, > and to help people review your contribution, > we ask you to follow the rules you find in the wiki at this link > https://openwrt.org/submitting-patches > > Please remove this message before posting the pull request. ---
