Not all of the RouterBOARDS with USB ports have the same supported features. This article list all supported USB features by each RouterBOARD.


Warning: On RB2011 and CRS series boards usb devices may not work first time they are plugged in. Power cycle (not reboot) is needed.

USB power reset

USB power reset turns off USB port power for specified time. It is useful when 3G modem needs to be restarted but there is no direct access to it (tower installation).

Available properties:

  • duration (time; Default: "3s") - Time interval how long power is turned off.

For example, "/system routerboard usb power-reset duration=10s" will turn off USB port power for 10 seconds.

RB2011 USB port mode

RB2011 series have micro USB port which operates in host mode when USB device is attached through USB OTG cable. Some vendor cables require forced host mode to recognize connected device.

Available properties:

  • usb-mode (automatic | force-host; Default: "automatic") - Defines USB port mode.

Note: In RouterOS v5 this setting was called "mode".

RB912 USB port type

RB912 series have USB port and miniPCIe slot. Due to hardware restrictions it is possible to use only one at the time.

Available properties:

  • type (USB-type-A | mini-PCIe; Default: "USB-type-A") - Type of enabled port.

Note: In RouterOS v5 this setting was called "use".
