All of sudden All 4 USB ports not working on Odroid N2 Plus
I measured 3.3V at pin #1, 5V at pin 2, and lsusb gives that :

Wow, I wonder what's going on with GL3523 on this photo. It looks like it cracked right next to pin 73 - AVDD33, and spread across the chip toward pin 22 (VP12_P2), pin 17 (VP12_P3) and others.

It appears your unit has dead USB ports, sorry about that. If it's still under warranty you should replace it.

Are you able to make even better photo of GL3523 chip? This is really interesting. I wonder if it is indeed cracked or just dirty.

Can you check the production LOT number?
It seems to be 2006('2020 June) but I am not sure since the picture is blurry.

Anyway, please contact "odroid at hardkernel dot com" with a URL of this thread.
They will help your RMA process if you purchased the board from our web-store directly.
Otherwise, contact your local distributor/reseller.

Looks like 2006 to me.
(sorry about rectangular artifacts, that's a misbehaving screenshot tool ;) )

I just ended up here with the same issue.
All 4 USB ports are dead.
It still boots from SD and eMMc and HDMI works.
Network (hardwired)works as well as I can SSH to it.
Watching syslog and plugging USB devices has no response.

I did plug USB switch with its own power supply but to no avail.

Mine says EL2006 001811

December 7th 2021 we had two power failures in the area.
Maybe that did the trick on damaging something (Odroid stays connected to power 24/7)

I am wondering if this is possibly a power supply issue ?
Or I need new board.

@kr16,
You need a new board since your board seemed to be damaged by uncertain electrical shock.

I just discovered that even though all 4 USB ports are dead the OTG USB port works just fine.
Plugged USB hub to it and everything is working fine.

Thanks kr16 for letting me know about the otg. Mine also works. I would still love to know the fault so I could repair it
