Thanks for the ticket but this isn’t a bug in TrueNAS software, this is more than likely a mixture of hardware problems and an upstream udev issue. Your kernel log is spamming the following messages.

Oct 26 11:25:15 truenas kernel: usb usb1-port8: over-current condition Oct 26 11:25:16 truenas kernel: usb usb1-port8: over-current condition Oct 26 11:25:16 truenas kernel: usb usb1-port10: over-current condition Oct 26 11:25:16 truenas kernel: usb usb1-port8: over-current condition Oct 26 11:25:16 truenas kernel: usb usb1-port10: over-current condition Oct 26 11:25:16 truenas kernel: usb usb1-port8: over-current condition Oct 26 11:25:17 truenas kernel: usb usb1-port10: over-current condition

That’s not good and means there is an electrical issue for the usb port. I’d recommend investigating what’s going on there because it could also resolve the udev issues as well. Either way, there isn’t a bug in TrueNAS that we can fix.
