Are there any known issues using the USB-Port with OpenWrt 21.02.1?
I do not see any reaction when I connect a USB device (hard disk / stick) on an running system.
It seems to me that the device is trying to boot from an attached harddisk on power on, but after booting from internal disk there is also no USB device available.
Can confirm: USB port does not even supply power.
@chunkeey, looks to me like another regulator wrongly initialized "active low" in the dts:
usbpwr: usb-regulator {
compatible = "regulator-fixed";
regulator-name = "Power USB Core";
gpios = <&GPIO1 2 GPIO_ACTIVE_LOW>;
regulator-min-microvolt = <5000000>;
regulator-max-microvolt = <5000000>;
};
I tried to decompile/change/recompile the dtb with the following regulator section:
usb-regulator {
compatible = "regulator-fixed";
regulator-name = "Power USB Core";
gpios = <0xc 0x2 0x0>;
regulator-min-microvolt = <0x4c4b40>;
regulator-max-microvolt = <0x4c4b40>;
regulator-boot-on;
regulator-always-on;
enable-active-high;
phandle = <0xf>;
};
(0x0 is the hex value for GPIO_ACTIVE_HIGH ... regulator-boot-on, regulator-always-on, enable-active-high I grabbed from your recent commit.)
With that change, the USB port is powered again, but dwc2 then fails when I plug something in, e.g. a USB stick:
[ 36.483848] dwc2 4bff80000.usbotg: dwc2_restore_global_registers: no global registers to restore
[ 36.492616] dwc2 4bff80000.usbotg: dwc2_exit_partial_power_down: failed to restore registers
[ 36.501019] dwc2 4bff80000.usbotg: exit partial_power_down failed
[ 36.517452] dwc2 4bff80000.usbotg: HC died; cleaning up
Another test with a Wifi dongle shows a kernel warning irq 36: nobody cared followed by a stack trace and Disabling IRQ #36.
The same happens if I remove the regulator section altogether, so I think there's another problem somewhere, one I am not able to diagnose and fix.
Thank you very much for looking into the issue. If you need some help for testing, please let me know.
Appreciated, but I lack the knowledge and experience to continue here. Hesitantly pinging @chunkeey, maybe he finds time to take a look at it.
new (fixed) builds are on the way. Check later today or tomorrow when they become available.
Fetched the wd_mybooklive-ext4 image from snapshots with upload date Mon Dec 27 20:26:09 2021. Unfortunately i have no luck with the sysupgrade and factory versions. The device gets an IP address via DHCP and i receive ICMP responses with ping, but it seems to me there are no listeners for HTTP or SSH.

HTTP not working is understandable of the Snapshots. They don't come with luci/uhttpd out of the box (but can be installed with opkg). SSH however should be working, especially with the factory images that restore the device back to default (and generate new keys).
(have you tried with just one HDD? This is in case it picks up an old rootfs from the other drive, the MBL's bootargs "root=/dev/sda2" are quite fragile in this regard.)
Thank you very much for your time and your support.
You are right, SSH-Login is possible!
But still no function on the external USB port.
In the meantime i have learned to build OpenWRT from source and the strange thing is, with my build - based on GIT hash 69ce75fb12526e11f79618a7cbedb32335b1f2bc, pulled master branch at Dec 27 2021 8:51 pm CET - the USB port works for me.
I will keep my build and configuration unchanged in case you want additional information.
Can you post some kernel logs from the dmesg command (from the snapshot)?
(And cat /sys/kernel/debug/usb/devices before and after adding a usb-stick)
The MBL snapshot images do come with kmod-usb-storage out of the box, so at least the any supported usb stick (there are a lot) should be announced and can be manually mounted. For automounting the blockd package is needed.
After downloading and preparing the current factory image snapshot (Wed Dec 29 11:19:40 2021) the USB port works as expected. The test was done with only one harddisk installed,
Possibly I was too early with the image on 12/27/2021.
Thank you for your great work and your friendly support.
