The usb port on my Pi Zero WH seems dead. I’ve searched around for similar issues and done some debugging, but wondering if anyone would have any more ideas on what to check before I declare it dead?
First of all, when I boot the pi, and then connect the OTG cable and check
ls /dev/, then no new device appears. When I also connect a memory stick to the OTG, then also no new device appears. Similar, when I check
dmesg -w before connecting the OTG & the stick, nothing new appears, and also no new devices in
Then ofc the question is, could there be something wrong with my software or hardware, i.e., the sd card, power supply, OTG or the memory stick? Now I happen to have a second pi around. This one is a Zero W, and not WH, so no headers, but my understanding is that otherwise, it’s the same board. So I plugged in the same sd card, power supply, OTG and memory stick to this Zero W, and it is working, i.e., here, I do get new devices, both in
ls /dev and
lsusb, when plugging in the memory, and I do get additional output in
Since the exact same software and hardware is working on the Zero W pi, but not on the Zero WH, I’m inclined to think that it’s a hardware fault in the WH. Do you have any ideas on what more I could check?
Just to align on how I’ve hooked things up, I’m attaching pics, both for the non-working Zero WH:
