I have a BBB with a tp-link adapter using the RTL8188EUS chip and it works well.
It is hung off a powered USB 2.0 hub from plugable.
I want to fire up another BBB but can not find inventory for RTL8188EUS based adapters.
It seems like they all disappeared!
I tried an adapter with a RTL8188CUS chip but it would not come up.
Inserting device lsusb sees it but connmanctl does not.
Is there a driver that needs to be enabled?
The adapter is off a powered USB hub.
I hesitated to buy one with RTL8188EU chipset.
Is there another adapter known to work on BBB Debian 9 out of the box?
If you could point me to one that would be great.

Probally just firmware, can you share:

Are you using the hdmi? can you disable it?
If your on v4.14.x-ti, i'd give v4.19.x-ti a quick shot:
sudo /opt/scripts/tools/update_kernel.sh --ti-channel --lts-4_19

Not using hdmi. It's disabled in uEnv.txt
Did kernel update
Linux beaglebone 4.19.94-ti-r41 #1stretch SMP PREEMPT Sat Mar 21 03:13:39 UTC 2020 armv7l GNU/Linux
No luck.
So, does this mean I'm stuck with only one RTL8188EUS with
no other options?

If your adventurous, 5.4.x-ti is available, with a caveat*

sudo /opt/scripts/tools/update_kernel.sh --ti-channel --lts-5_4

sudo /opt/scripts/tools/update_kernel.sh --ti-channel --lts-5_4
returned a list and asked me to choose one so I tried
sudo /opt/scripts/tools/update_kernel.sh --ti-channel --testing
No good. So I tried
sudo /opt/scripts/tools/update_kernel.sh --ti-channel --lts-4_19
And it put me back where I was. 5_4 was not on the list.
