[SOLVED] USB Wireless Dongle Not Recognised as Network Adaptor

I got hold os a TP-LINK TL-WN823N USB dongle and want to set it up on a desktop machine that currently has wired access.

When I first plugged it in, it was recognised as a network adaptor, and given a name something like enp0s8u2s3 or similar. When I tried to set it up using iwconfig (iw listed blank), it told me that it had no wireless extensions. So I looked around and found the 8192cu-dkms module in the AUR and tried that. That made no difference. A bit more searching and I find this module via this thread. I tried installing that and then now the adaptor is not even recognised as a network adaptor. I uninstalled it, same result. Re-installed the AUR package, same result. Uninstalled that and tried manually loading the kernel 8192cu drivers, same result.

The output of lsusb is :

Bus 002 Device 004: ID 0411:00a2 BUFFALO INC. (formerly MelCo., Inc.) 
Bus 002 Device 008: ID 2357:0109

Bus 003 Device 003: ID 058f:9254 Alcor Micro Corp. Hub

Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

The adaptor is 002:008 and unidentified.

After plugging in, dmesg gives:

[ 2661.635247] usb 2-3: new high-speed USB device number 8 using ehci-pci

So it looks like I've borked something up. Any ideas what, and how to at least get it back to being recognised as an adaptor of some sort, again?

Seeing

Bus 002 Device 008: ID 2357:0109 

Is not an issue, it just means no one has added the info to the USB database.  The driver from pvaret's github does not include that ID so it won't work

https://aur.archlinux.org/packages/rtl8192eu/ might work as it shows it uses mange's github source but it needs to use one of the latest patches to support your device
https://github.com/Mange/rtl8192eu-linu … 36eff1416d

I added the device ID to the database, see if lsusb results change after

sudo update-usbids

Re: [SOLVED] USB Wireless Dongle Not Recognised as Network Adaptor

Excellent, thank you!

It's been so long since I needed to do anything at this level, I had forgotten to look into the usb ID's.
There's still a mystery as to why it could be seen at the start, but it's not one I'll worry about.
Marking as solved.
