  1. To be honest I don't really know.

    I don't have PCI-E usb cards other than the ports provided by the motherboard.
    So ASM2142 is either the USB HUB's chip either the motherboard's chip.

    As I said I have a big USB 3.0 HUB plugged to the only one USB 3.1 port.
    I'm passing through this port / hub in order to have no issues with the USB devices plugged to it.

     

    This morning I found 30mn to test the VM with ACS overide off.
    I saved the devices webpage without ACS overdrive enabled.
    I will share it later as I forgot to start teamviewver so I can't access my system from work (student's shared wifi not allowing me to forward ports etc).


    I started the VM successfully without any error in the log, when ACS overide is disabled, therefore when not passing the USB HUB/port.

    With the actual IOMMU groups I can't passthrough my usb 3.1 hub.

    Possibly I should pass all devices from the group ?
    I think the sata ports are part of it. In a few weeks I will receive a HBA card so possibly not a problem?
    Updating tonight or tomorrow.
     

  2. Actually I have no idea but I reported it as I don't wanted to mislead anyone.

     

     

    Maybe you are right ?

    How could I check if it's the case?

     

    I'll try to turn off PCI ACS override, but do we agree that if the IOMMU groups aren't broken enough for GPU and USB passthrough, I have no other choices ? I'll copy/paste the original IOMMU groups here to investigate.

  3. Thanks, I corrected my post. It's been a few weeks for me in the unraid world. I got to so many parity repairs, which are caused by hard reset. It seems like a similar behaviour.

    What would be the best test to confirm it ?

    Should I remove passing this usb pci controler in Unraid OS options and try to see if windows VM accept to reboot?

    Usually never works for me.

    Be aware I also ran in a case where no VM were working anymore ; I got to reinstall unraid.

  4. Hello,

    Thanks to Modo johnnie.black who linked me this topic, I can confirm I also have that bug.

    I'm also passing a usb port integrated to the MB where an external USB hub is plugged :

    ASMedia Technology Inc. ASM2142 USB 3.1 Host Controller | USB controller (08:00.0)


    This is the only usb 3.1 gen 2 red port I have to the back of my Asus X399 Strix motherboard.
    I use a KVM switch to pass mouse/keyboard/so on from Unraid (other usb 2.0 ports) to windows VM (one usb 3.1).

     

    Here's the diag and log while W10 running just after reboot :
