Too bad it won't run 7.x. Here is the tread from when some of us were having the usb issues: ESXI USB reset A quick look at the log should help show if you are caught in this problem. IIRC, you should be able to add a 2nd USB device( UPS unit?) and that may fix it( no idea why) Also, if you have a spare PCI slots you can pass through acard with USB ports for the USB drive, but think you would need to boot from vmdk instead of Plop if it's not the USB reset issue, report back and will try to see what else is going on. Good luck.

Hi, I had a lot of USB issues using esxi 6.x. there's is a big thread on the issue I and others were having from a few years ago. The best fix for me was upgrading to esxi 7.x. it fixed all my USB issues and even better allows you to direct boot the VM off of the USB drive. No more plop or vmdk's, just boots and updates like it was on bare metal. If you can't upgrade to esxi 7.x for some reason, let us know if this was a working system that just started acting up or was it after an upgrade on either eexi or unraid. Also check your vmkernel.log for errors to point in the right direction.

@miicar You don't say which ESXI version you are on. if possible, I highly recommend trying to upgrade to the latest 7.x ESXI. It allows you to direct boot the vm from the Unraid usb. I am also not seeing any of the usb reset problems I had with 6.x. if you are staying with 6.x ESXI, you can try adding a 2nd usb(ups unit?) or what i did which was to add a pci usb card and added the usb port from that.

Yes, Flemming's how-to is showing how to do just that. ESXI 7 allows you to add the USB Drive to the VM and boot the VM direct from the USB. No more playing with PLOP or VMDK's like prior ESXI versions. Works great.

UnRaid 6.9 is working for me under ESXI 7.0b booting( EFI ) directly from USB Flash drive my setup: Norco 4224 / SeaSonic X750 / SM X9SRL-F / Xeon E5-2640 v2 / 32GB U-ECC / M1015 / RES2SV240 / ESXI 7.0B / UnRaid 6.9

@Flemming Thanks for the write-up for ESXI 7.0 install, the EFI boot part really helped me I know you were doing a conversion to ESXI, I was doing a clean re-install of both. Just wanted to add a note for anyone installing with an clean Unraid flash drive. I used the "Unraid.USB.Creator" for my flash drive and choose the "Allow UEFI Boot" under "customize". By doing it that way I can skip the "Add Boot Option" and go directly to "Change boot order". FYI, I am now running ESXI 7.0b and UnRaid 6.9 on a Supermicro X9SRL-F motherboard. It works well, except dhcp is not being passed to any vm. Static ip's work normal.(will look into further)

None of the fixes had really worked well for me. I ended up adding a 4 port usb pcie card: https://www.amazon.com/Express-SuperSpeed-Adapter-Dedicated-Channels/dp/B00HJZEA2S but I am still using a VMDK for booting ( I think I tried usb boot and never got it working right.) This setup works well for what I need. It was a bit expensive, but i can pass each port to a different vm if needed. They list a 2 port which is cheaper and shld still work fine.

@uldise - I'm not sure why yours works and mine doesnt. do you have the UPS passes thru to the vm also. I know that workaround was working for some. Have you checked your ESXI logs to verify no warnings/errors? just an update: When I clean install or upgrade to ESXI 6.5 I was seeing a bunch of errors on my datastors: I got this fixed by disabling the new sata driver -"vmw-ahci". Once i found it, it was easy to fix following this guide: So ESXI 6.5 is running ok, but i still see trouble with adding the UnRaid usb: sample of ESXI log errors: Any other usb drive works fine, so I started looking at whats on the flash drive that could trigger this. I put the flash drive in a laptop and deleted the "ldlinux.sys" file. when i plugged back into the server - the errors stopped. i added the unraid flash drive into a windows 7 VM, when i ran "makebootable.bat" it re-created the "ldlinux.sys" and the esxi errors started back up. I renamed the "ldlinux,sys" and the errors stopped. put the name back and the errors did not start again. i rebooted the win7 VM and it would not start with the unraid flash attached. I found the errors i'm seeing in a ESXI forum and posted there. if anyone is interested : Does anyone know what is in the "ldlinux.sys" file or how it works?

Thanks Uldise, good to know. Did you upgrade or clean install to 6.5? I'm going to try to upgrade from 6.0 to 6.5 (instead of clean install) to see if that fixes my issues. will let you know how i make out.

You had me excited that this was finally fixed. Unfortunately, clean installed ESXI 6.5 and its giving me all sorts of odd issues (using X9SCM-IIF MB). cant get unraid to boot-the usb device disappears from the vm(any VM). The esxi logs (dont think its isolated to unraid) -"dev = usb0105, cmd = 0x8004550f, err = -2: Failure" and my datastors all get "state in doubt; requested fast path state update" in /host/vmkwarning.log. oddly my oldest datastor drive doesnt show this error. Seems like a problem with the sata and usb controllers. So for now I'm going back to esxi 6.0 , but will give 6.5 another try in January when i get free time. please let me know if anyone gets esxi 6.5 working well on supermicro x9scm board. thanks.

When i was trying to setup the usb card I tried Plop + Plopkexec and it could never find the usb. The card is PEXUSB3S44V - Startech Renesas_uPD72020x chip. It just seemed like there was no driver there for it. Does anyone have this card/chip working with Plopkexec? I guess i can give it another try when I update to 6.2.3

I have been using : www.amazon.com/gp/product/B00HJZEA2S in my ESXI box. its a little pricey but it lets each usb port to be assigned separately to different vm's. you can get the cheaper version, but all the ports get passed to 1 vm. I'm still on 6.1.9, hope to test the latest versions in the next week or two. I cant usb boot with this setup(guessing a driver could be added) so I am using VMDK and just put the "UNRAID" usb in the port that i passed thru.

Been a long time for me too. I think the bios for the cards is "ctrl-H" (maybe "cntr-C"? - it should pop up on the screen during boot) Check to see if ESXI still has them available for passthru ->"configure ->Advanced Settings" Also check the VM settings still shows the 3 cards passed thru?

Its mounting RW now. When I ran fsck from UD before posting it returned "appears to be OK". but in the system log: kernel: hfsplus: Filesystem was not cleanly unmounted, running fsck.hfsplus is recommended. mounting read-only. running fsck with -f fixed it. Is there a way to show the "not cleanly unmounted" msg from the syslog in the UD log? Thanks for the help dlandon. and Thanks (+gfjardim) for UD - it is very useful.

I am trying to Mount a hfsplus drive with UD. It wil only mount as read only. I dont know if this is by design or if I'm having a problem. It is a friends drive and I think journaling is enabled, but don't know if that is causing the Read Only. Is there anyway to make this writeable? Also, how can i verify hfsprogs is installed?
