Mikrotik RB952Ui-5ac2nD no power on USB port

Dear colleagues, I've recently bought Mikrotik RB952Ui-5ac2nD and trying to make it happy with huawei e3372h 4g lte.

Unfortunately I have no power on the USB after openwrt boot.

Is there any solution? The link above does not work for me :frowning:

Which branch/firmware did you build/flashed to it?

openwrt-18.06.4-ar71xx-mikrotik-rb-nor-flash-16M-ac-squashfs-sysupgrade.bin from here: http://downloads.openwrt.org/releases/18.06.4/targets/ar71xx/mikrotik/

I can easily flash/test the .bin, but it will be very difficult for me to build. Can you help with any direct download link?

I think the issue is that your board is:
RouterBOARD RB952Ui-5ac2nD

While the board detect code in 18.06.04 only knows about:
RouterBOARD 952Ui-5ac2nD

This was fixed in 19.07 and Master, but not backported to 18.06.

Please try following:

  • Open a ssh window to your board
  • run cat /proc/cpuinfo and check if it mentiones RouterBOARD 952 or RouterBOARD RB952

If you see RouterBOARD RB952 here :

  • edit the file /lib/ar71xx.sh
  • search for RouterBOARD 952Ui-5ac2nD
  • alter it to RouterBOARD RB952Ui-5ac2nD

save & reboot

Changed the boardname, but actually this didn't help very much.

Real machine name: MikroTik RouterBOARD RB952Ui-5ac2nD

so updated the file:

*"RouterBOARD RB952Ui-5ac2nD")

The usb is not alive :frowning:

Thanks for testing.

You should leave this fix in, as it will have fixed other stuff too.
It's also required if you want to upgrade to something else later on.

The USB should this be seen as another issue.
Unfortunately, I don't have this board here.

Could you provide a full output of dmesg?


Hello! Are there any changes to power the USB port? Tried versions of 19.07.04, 19.07.05, 18.06 with all usb does not work. The only thing that found it exactly it works from usb hub with active power. Has anything changed in 1.5 years?
