Been a long term user of Linux, mainly Debian type distros but I am new to Open-WRT.
Installed it on a Raspberry-pi 3B as a project, all working fine, ethernet connected to network and onboard wifi acts as an Access Point.
To inprove range I bought a TP-Link AC600 Archer T2U plus, it seems to use the rtl8812au driver and I have installed that using the luci interface. Still not recognised.
Do I have to install any firmware? There doesn't seem to be anything specific for this driver.

There is a big output from lsusb -v -s 001:004 and I am not sure what is relevant to wont post loads of info unless you are interested in anything specific.
Thank you for being so condescending as to suggest I do a bit of reading, if you read my post you would realise I did not suggest it should work out of the box, my research suggested realtek was well supported by Linux.
Forums are not places to be admonished for asking questions, if everyone actually did very deep searches for every query then forums may eventually die, as Fidonet virtually has.
slightly off topic.....if you can't get it to work I can suggest a Ralink RT5572 based stick, for example that one. It works flawless in OpenWrt, but keep in mind it's only 802.11n, expect ~40Mb/s on 2,4G,20MHz and ~70Mb/s on 2,4G/5G 40MHz (from my testings)
Don't forget AFAIK Rpi3 NIC shares bandwidth with usb ports so data rate is limited anyway.
If it's all about coverage, you could decide welding an antenna connector (if not there anyway) to the onboard wifi and use an external antenna!? I guess there are tons of tutorials on web.
someone on IRC wanted to try rtl8812au from morrownr
I also did some changes to the repo used in Arch Linux AUR for rtl8812au-dkms-git
both are 5.x versions compared to rtl8812au-ct currently in OpenWrt which is based on 4.3.14
Realtek drivers are really messy
so I created two Pull Requests / Makefiles
and
with both drivers scanning works but joining a WLAN does currently not work
feel free to test or comment here / in the pull request
for testing I used a TP-Link Archer T4U attached to a virtual machine (qemu) running OpenWrt
edit: lsusb reports
Thank you for suggestion, 802.11n would be fine. I've got an extra AP working via a powerline connected in my home. The R-Pi and OpenWRT was an initial experimental project to get a signal in my garden and to see if I liked the option of upgrading my router to a device that could take an OpenWRT firmware.
