I’ve emailed Pimoroni about this as well but thought it worth posting here.
I’ve just taken delivery of a Pi Zero (not W) and a “Three Port USB Hub with Ethernet - microB connector”.
While trying to update a new Stretch SD card, I’ve experienced lots of problems of just losing connection to the Pi. I can leave a continual ping going, after a while, it just stops.
By a process of elimination I’ve traced the problem to the ethernet adapter.
At the moment I have this adapter plugged into another Pi Zero (this time a W) which I’ve connected to via WiFi.
While trying to install snmpd, I lost connection via ethernet again but I’m still connected via WiFi.
ifconfig shows eth0 has vanished.
I’ve used multiple different PSUs including an official Raspberry one and about three different cables.
I’ve plugged into different ports in my router and used different ethernet cables.
Has anyone experienced this? The Three Port USB Hub with Ethernet - microB connector just effectively disappearing into thin air.
The lights in it are still on and so is the activity light on the router.
Any thoughts please? Faulty part, maybe?
