@Joe_90 I have my N2+ here. I can try to reproduce your issue. Give me some info what you did. Emmc or SD card? Flash 9.2.3 fresh?
OK I think I could reproduce it
I have enabled usbpower and now my usb are dead on boot. I need to replug my usb
It’s an N2+ 4GB. It’s got the battery holder soldered to the board. Do you have one also? The black plastic cover around the USB, ethernet, HDMI ports at the back seems to be glued on. The rest of the cover comes off ok. I’ve replaced the CR2032 battery as dmesg was complaining about low voltage on the rtc, but it’s still complaining even though I’ve measured it at 3.2V.
I have to go out shortly, but I’ll be back later in the afternoon. I was considering joining up on the odroid forum to make contact with @tobetter, so your suggestion is good.
Can you point me at the section of this forum where I can remind myself how to set up an IR remote? I have a couple here - one from a Tronsmart and another from a Venz V10 Pro. I’ve tweaked IR code settings before on Libreelec, but have been using the RF remote and dongle for years - so much easier!! I find the layout of the coreelec forum a bit tricky to navigate.
Thanks for the assistance. I don’t mean to be cluttering up this thread - maybe I should start a new thread?
Well I have destroyed my N2+ too. I could only see a little bit of smoke.
The box came with 9.2.3 stable installed on eMMC. I booted that and set up my basic config, locale etc and set up an SMB route to my NAS. After that I uploaded the ng nightly tar to the Update folder and re-booted. That’s all she wrote!
WTF!
Smoke?? How could there be smoke with a software update?
The only thing I did with the initial config was to enable USB power on shutdown/suspend.
It is the usbpower option. Now my usb3 is broken too 
How did you succeed to do that?
I’m glad you can see the funny side! Were you serious about the smoke?
Yes I was serious. All I did was enable usbpower. Then I rebooted. Replugging still worked. Then I disabled usbpower and rebooted. Then I saw a tiny bit of smoke come out of it.
This option is a usb3 controller killer so it seems. I need to remove it.
It’s best if you exchange your N2+.

I dropped an email to odroid uk (support@odroid.co.uk) last night. Nothing heard back yet. I assume this is covered by RMA? Will you be in touch with @tobetter about it?
I’ve got to leave now and will be back in a couple of hours. Commiserations on your dead N2+
Joe
I don’t know if it’s covered by RMA. But you don’t have it long. Mine didn’t last long either 
I don’t use USB so it’s fine.
Will you point me at the section on the forum where I can research getting a standard IR remote configured? If odroid uk won’t play ball with an RMA I may have to look to other options. It’s crazy design that a software setting could blow up a board, though! It’s not like a processor overclock… going out now.
You are EU citizen. You have a warranty and UK is not brexit yet. I would not go into details. Just say it’s broken. Came broken.
Wow, that’s a bummer!
Yes, that’s why it’s N2+, not N2 rev.5. So we cannot expect to have full HW compatibility.
That’s why I’m eagerly waiting for HK to release the schematic & SOC spec. Who knows what else was changed on schematic level…
The new SOC may also require different voltage tables, compared to N2, so it may be a risk to operate with N2 BL?!?
I think it should be exchanged by odroid uk store. They sell this as a CoreELEC edition even though it doesn’t exist.
Hello, @Ray made me look into this problem. Let me try to research the problem and will have an internal discussion if your device can be covered by RMA or not. It would be nice if you can make a photo of what USB devices are connected and which port is being used, and share with me through private message. Sorry to hear your device has defected.

Is that some jumper setting, or some software switch? I asking just to be sure, I never touch that option even though I dont have N2+ 
Edit: just read Nightly builds (NEW)
It is a config.ini setting and only relevant if using N2+. It is good people are aware of it.
A new marketing opportunity arises.
Free smoke alarm with every N2+
