How to configure USB WIFI dongle

Any ideas how to get my wifi dongle working? I have a Raspberry PI running the latest version of OpenWrt. I purchased a TP-Link AC600 Archer T2U Plus wifi dongle and plugged in the dongle. It displays "RTL871X: rtw_ndev_init(wlan0)" in dmesg but the wlan0 interface never appears in luci or ifconfig.

I installed the following drivers

kmod-rtlwifi-usb
kmod-mac80211
kmod-rtlwifi
kmod-usb-net-rtl8150
kmod-mii
kmod-usb-net
kmod-usb-net-cdc-ether
kmod-usb-net-rndis 

lsusb displays

Bus 001 Device 003: ID 0424:ec00
Bus 001 Device 006: ID 0b95:1790 ASIX Elec. Corp. AX88179
Bus 001 Device 005: ID 2357:0120 Realtek  802.11ac WLAN Adapter
Bus 001 Device 002: ID 0424:9514
Bus 001 Device 001: ID 1d6b:0002 Linux 5.4.154 dwc_otg_hcd DWC OTG Controller

When I plug in the dongle, dmesg displays

[ 1316.434977] usb 1-1.5: new high-speed USB device number 5 using dwc_otg

ifconfig displays (note wlan1 is the existing built in wifi)

if a network device is not presented you have driver issues...

if you have a network device and no luci, you have config issues / incompatibilites which usually provide enough info in the log to track down relevant infos...

My output looks similar to yours. You said config issues provide enough info in the log. Is there another log I should be looking in?

uci show wireless ?

Hi, I have the same problem getting the device working. Any help would be appreciated.
