EV620 on RB411U Question-Visible on PCI but no serial ports

I have a Toshiba branded Novatel EV620 (Shows EV620TV1 on card) in an RB411U. I see it under Resources/USB (VendorID 0x0930 DeviceID 0x1301) but I don’t see any serial ports associated with it.

Looking through the forums and supported hardware list the EV620 is apparently supported so is there something else I need to do to expose the serial ports or is this Toshiba branded unit perhaps showing different IDs to the OS?

RouterOS version is 4.2.

TIA for any pointers. :slight_smile:
