Driver for Ralink MT7601U USB Wireless Adapter

I am new here. I run Linux (Fedora) and a friend has just asked me to help with his TrueOS system installed a couple of days ago.

We are trying to get TrueOS to recognise his USB network dongle.

On my Linux system, lsusb returns:
Bus 002 Device 005: ID 148f:7601 Ralink Technology, Corp. MT7601U Wireless Adapter
and the device is immediately usable.

On my friend's TrueOS, I can't find the device at all.

Am I looking in the wrong place, or does TrueOS not have drivers like these built into the kernel as Linux does?

Thanks in advance for any help.

Very strange, since the device (chip) is well known cheap WIFI and not a novelty at all.
Mediatek (previously Ralink) MT7601. Not run(4) nor rum(4) (and obviously not Realtek's rsu(4)) are working for my FreeBSD-11 stable…
Although, Linux has support for it according to Wikipedia
