I have installed Homeassistant on my ASUS T103H laptop, originally windows was on it. It has only one USB port.
I am going to use TP-link UE200 network adapter (USB 2.0) and Sonoff Zegbee 3 plus USB dongle. To accommodate two USB devices, I purchased Logilink UA0141A v2 USB hub with external power adapter 5v 2A.
It seems both wi-fi adapter and TP-link UE200 network adapter are working. They got ip address and I can ping those ip addresses.
Unfortunately, TP Link adapter is not working via this USB hub and I cannot connect to homeassistant server.
What is the solution to make it work both the Sonoff Zegbee dongle and the TP-Link network adapter ?
It sounds like you have done it correect physically.
The reason it might not work is because the HA code does not have a driver for the TP-Link adapter, so it will not be configured as a network adapter.
You can suggest the devs to include the driver for the adapter, but sometimes the license attached to the driver software is so strict that they can not include it without breaking that license.
Often the easier way is to ask on the forum for a list of supported adapter and then get one of them instead. It will definitely be faster, because the HAOS needs to be updated with the driver first and then it needs to published as a new release, which can easily take a month or more.
