ESXi freezes on "loading module usb-storage"

hi everyone,

I have a homelab based on Intel NUC D34010WYK.

Few days ago, i was on ESXi 5.1, yesterday i tried to update on 5.5.

One of my NUC is on 5.5 without any problem...

The other one freeze at the first boot on "loading module usb-storage"

and i have this on logs : see attachment

My ESXi is installed on USB sticks, so i tried to use the working usb sticks on the NUC that freeze ... and it did not work... same error

Do you ave any idea, to bypass this module ? because after 12 hours, my ESXI is still not booting...

Thx

Hi there,

over-current pretty much seems like too much juice is flowing into the USB pots - perhaps a HW went somewhat unluckily defective? You could check your BIOS for any USB power-related features and disable them, or maybe change your boot mode to EFI and try reinstalling the hypervisor. Otherwise I fear there's not much else you can do other than switch to another USB port which NUC doesn't have many of I fear... could you try an SD card if available?

Not sure if D34010WYK mini-PC is suitable for ESXi, but "over-current condition" means some device (usb, mouse, keyboard, etc) wants to get more current than usb-specification allows (usb 2.0: 5V/0.5A). This might be even device that normally does not need more, but during its start-up there might be power-peak (typically: notebook 2.5" drives).

Some OS do not check this, and some HW do not even set any limits. But apparently EXSi 5.5 monitors it and it is quite understandable, as overloading USB might lead to instability. Check what you have on ports 3 & 4, and if possible, switch it for some low-power version. One more possibility is to use different ports (sometimes a few usb-ports share the same power-line), so try moving your usb-devices around...

Well, first thank's for your answers.

With your help i continue to search about this problem... and i saw that only two of my 4 usb ports works... I checked on the bios and everything is enable and everything seems ok...

So, i think i have a hardware problem, i will contact the Intel support ... and will see ^^

I keep this thread open ... and i will update it when i have new answers Smiley Happy

thank you
