Hi Steven, no I don’t have any links at hand but I came across a thread about this.
This just happened to me as well. I purchased a Blue right when they were announced ~18 months ago and last week the USB ports died (taking down my Zigbee and RT-SDR USB sticks.)
I ordered a replacement from HardKernel and it arrived pretty quickly from South Korea. I first tried a new power adapter with the original Blue, but the USB ports still did not function.
I shutdown the Blue, swapped the motherboard and memory chip, re-assembled, updated my DHCP lease to accept the new MAC address, plugged it in and it started right up again.
It made me think about having replacement hardware around for situations such as this. I’m going to get a Home Assistant Yellow box and see how that performs. I’m not sure how much of an upgrade it will be (other than ssd support and a new zigbee chip) over the Blue. It’s not clear if the Pi CM4 performs better than the Odroid chip or not. Whatever I end up using longer term, I think I will order a backup set of hardware to have on site… just in case.
ok, I updated my HA Blue to HA OS 9.0.rc1 today, and something must have went wrong, as it would not boot anymore.
I connected to the HDMI and I get the message that HA CLI not starting.
So I tried to connect a USB Keyboard to do something, but I get no response.
Is it a valid assumption that I’m also a victim of the N2+ USB Issue?
I have a HA Blue since they were launched and been working fine. A couple of days ago, all 4 USB ports stopped working completely. I use a Z-wave dongle via USB, so now the Blue is close to useless. More e-waste which is a shame, as it had been very reliable until this week.
Oh man. I just updated my Home Assistant OS and mine died. This is really disappointing not that I have moved to using so much bluetooth…
Spoke too soon. 2 more hardware resets fixed it. Still makes me weary of the product now though.

did anyone try to use the microUSB on the back to plug in a active USB hub?
Yes, that works. I connected my USB-ZWave Dongle to the microUSB port on the back. Fingers crossed it will continue to work.
I found this article about how to reset the USB ports and control their power supply: https://wiki.odroid.com/odroid-n2/troubleshooting/hub_reset The ODROID-N2+ seems to be able to control USB power in software. It needs root access to the host’s OS though. Will try to gain access to the host’s OS and test if I can revive my USB ports.
I do not see it, is it on the blue (ODROID-N2+)?
Today it happened to my Home Assistant Blue as well after a reboot.
The Blue is only 20 months old.
I had to move my Zigbee-stick to a raspberry pi and then configure zigbee2mqtt with socat and ser2net.
Can it be fixed?
You can try replacing the 7805CT - see above. Also there are some wiki refs above you can try.
It is hidden underneath the case, just like the ir diode
Yeah, thanks for the response. I did not realize there were more ports underneath.
In the mean time I sent the board to Hard kernel for repair.
Sitting on pins and needles now. I love my Blue. FWIW I’ve been powering it over PoE using a Texas PoE adapter since the day I got it up and running…
Did you ever managed to reset it? a script for resetting would be great… the only way I get it done right now is a restart of the whole system.
Oh, thanks for catching up. Nope, never got the USB ports back to life ever again. I migrated to a Intel NUC as Proxmox host and installed my Home Assistant OS installation into a VM.
Mine died also.
Uuugh.
Very sad and disappointed.
I thought I’d respond to this issue as I’ve just experienced this myself yesterday. I have an ODROID N2+, and for at least a couple of years, it worked fine with a Zigbee stick and a bluetooth adaptor in two of the USB ports. I updated to OS 11.2, and the two devices stopped working. Thinking that the upgrade broke something, I rolled back to v11.1, but nothing changed - the USB ports were dead. I check with a USB power meter, and it did not switch on.
However, I did notice that the power meter switched on briefly during a reboot. I saw a comment earlier about changing out the PSU made a difference, so I switched out the PSU that I had been using since I got the ODROID for a 12V 3.3A version, and the USB ports are working correctly again!
So, I guess if you have an ODROID N2+ with apparently faulty USB ports, try changing out the PSU for a beefier one, even if the existing one has been working for a long time. It might just well be the cause of the problem!

I take my previous suggestion back. On rebooting after an update to OS 11.3, the four USB ports flicker on briefly on startup, and switches off for the rest of the time. This causes my bluetooth and zigbee sticks to be unpowered, and therefore, unrecognised in HA. No amount of rebooting changed the outcome, but I did notice that the period that the USB ports are powered seem to vary with each reboot.
Like @worm5406, I’m sad and disappointed by this development.
In the meantime, I’ve decided to give a ethernet/wifi to zigbee bridge a go (https://www.tindie.com/products/smartlightme/smlight-slzb-06m-zigbee-ethernet-poe-usb-wifi-adap/), and use the N2+ as an ethernet-only device. Bluetooth functionality isn’t critical, but I’ve got plenty of ESP32 around to make a wifi bluetooth proxy if need be.
Thanks @welshcoder , I am sorry that others are at the junction also.
I got an odroid m1 combo and have been happy after the migrate over. Just wish there was an easy OS update.
