Hi there.

I've updated my proxmox (apt update && apt full-upgrade).
After the reboot, my USB ports of my Asrock N100DC-ITX are partly not working. To be more specific, these ports + my front USB stopped working:

I can't 100% confirm that it's related to the update, since I didn't immediately restart my server, but I can't think off what else could be the cause of this.
Any idea how I can debuff this further? I'm no linux expert, so I'm not really sure :(

Thank you in advance!

I can only link a problem I appear to have here, although in my case everything works, until I start copying some files & only then my WHOLE USB bus fails. Also on my system (not similar I believe to yours), if I use a USB flash drive (non UAS) as opposed to a SATA to USB (UAS) I have no problems. So I'm not sure we are related. My problem also only started after recent upgrades.

It's probably the USB controller not playing nice with the iOMMU. Try adding intel_iommu=off to your kernel parameters (it was turned on by default by Ubuntu/Proxmox) in kernel 6.8.

Not sure if I did this correctly. I've nanoed /etc/default/grub and added
Code: 
intel_iommu=off
followed by update-grub
Because it didn't detect my usb pendrive I've also rebooted, but still no luck unfortunately. Did I do something wrong?

I don't think that we have the same issue, because mine doesn't detect anything unfortunately.

I can't tell from the little information here, nor do I know for sure that this is the problem/fix. Which bootloader is your Proxmox using? What is the output of cat /proc/cmdline ?

This is the output for both:

Code:

Sorry if I didn't provide enough information, but I'm really not that experienced with that and not sure what else I can/should provide.

As you can see intel_iommu=off is not there (and it probably looks nothing like you saw in /etc/default/grub). You probably need to edit the other bootloader (systemd-boot) in /etc/kernel/cmdline (everything on the single first line, no additional lines): https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysboot_edit_kernel_cmdline

Ah I've found it. The /etc/kernel/cmdline was completely empty. But thanks to this thread i figured out that I had to add it to GRUB_CMDLINE_LINUX_DEFAULT rather than pasting it just at the end of the file.
Now my bootloader looks like this:
Code: 
root@homeserver:~# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-6.5.11-8-pve root=/dev/mapper/pve-root ro quiet intel_iommu=off
Unfortunately this didn't fix the USB though :(

I've just checked dmesg -w if the insertion / pulling the usb pen drive shows anything.
While for the first 4 ports it's detecting the pen drive

Code:

it doesn't show anything for the front USB nor the two marked from post 1.
It really looks like the USB hub is gone or something :(
 
I've once had a USB TV tuner break all the USB ports on a motherboard. Does the motherboard BIOS see devices connected to those ports?
Maybe boot a live Linux CD (like GParted Live or Ubuntu installer) and see if the USB ports work if you are not using Proxmox.
 
Hmpf, you may be right...
Just connected my keyboard to one of the ports - it doesn't get power, nor did I manage to get into the BIOS using this port. So it really looks like the ports are dead :\

Looks like I'm gonna RMA the board :(

Interesting. Did all the said ports work - before PVE update?
 
Yes. I was using my sonoff zigbee adapter on one of the ports.
And the BT adapter was connected to the front USB.

Did you try shutting down machine - remove all power - then restart & try port/s?

This actually seems like it has fixed the issue!
I've tried shutting it down (without removing power), but this didn't help. I've now removed power for like a minute, turned back on and it seems like the ports are working again :D

Thanks a ton (to all!)!

Then it probably was a short-circuit, ground-fault or overload protection that got triggered. Thank you @gfngfn256!
