Boot from USB-PCI-Expansion Card + Passing through creative soundcard


Recommended Posts

Hello unRAID Forum,



all my mainboard usb ports are connected to one bus so i cant pass it to a vm.

I have read alot of different things about pci expansion usb cards and most people say that you cant boot a usb stick using them.

Whatsoever all theses answeres and stuff are from forums 5+ years old and maybe things have changed nowadays. Now i just try asking here is it possible to boot unraid with a pci (not pcie) usb card? Does it work for anyone and if so does it work with any card? 


My second problem is that i cant pass through my creative soundcard, its a creative x-fi soundblaster. Using the onboard sound works fine.

When i pass it through using the gui, the vm has no sound (obviously) but also youtube videos dont play and windows says that the microphon is always like at 100% (that indicator telling you what the mic picks up).

The soundcard is in its own iommu group too.


If you need any more details let me know, im new to unraid though so a little explaining is necessary.


Thanks in advance. (also sorry for poor english)

You probably will need to provide the Gurus with a bit more information.  First, you need to post up the manufacturer and extra model numbers of your motherboard, pic expansion card, and model of that sound card.  It would also be good if you were to post up a diagnostics file with your next post.     'Tools'   >>>   'Diagnostics' 

EDIT:   Did you read this section of the manual and verify that your MB will even support the level of virtualization you are attempting to achieve?




EDIT #2   You also need to include the exact model number of your CPU.

Thanks for your answer.

I attached my diagnostics and here are my specs:
Mainboard: ASrock pro4 z97
CPU: i7-4790k at stock speeds until everything works

RAM: 16gb 1600mhz

Soundcard: Creative SoundBlaster X-Fi Titanium Fatal1ty Professional (PCIe)


My MB does support vt-d and vt-x so does my cpu, I have successfully passed through my gtx970.


Yesterday I created a second VM with a fresh windows and the soundcard worked right away, doesnt in my main VM though. (same settings and method for passing through)

So there might be something faulty with my current install.


Anyways my "main" problem is the boot from usb card. I don't have a pci usb card yet but i don't want to buy one just know it doesnt work.

iommu 1 is my graphics card which also works
