Anyone have a solution for this? Or a doc or guide to point to? I've been struggling with this same issue since moving off 6.9 last year.

I had the exact same issue as the OP in my Windows domain environment. This was extremely frustrating since the SMB shares were working fine for almost a month, then suddenly I could not connect to them with the very account I used to set the permissions with! I had used a domain admin account to set the permissions on the shares and granted full access to "domain admins", and less access to a couple user groups as appropriate. I discovered (from running the Fix Common Problems full scan) that UnRAID saw my domain admin account as a "domain user". I looked in Active Directory and realized it was a member of both groups. I set Domain Admins as the primary group for this account, removed domain users, and immediately I could access the UnRAID shares with this account again.

That did the trick! Thank you both for your help!

Great find! Thank you! Follow up question, if you don't mind: Step 2 says to edit /etc/default/grub and add GRUB_CMDLINE_LINUX="iommu=soft". From what I can tell, UnRAID doesn't use grub. What is the equivalent I should be looking for? Where should this edit be made?

I checked, and it is running the latest BIOS - and by latest, that's 2016. Is there a detailed post on troubleshooting USB devices in Unraid somewhere?

I have UnRAID running on a Gigabyte GA-990FXA-UD3 motherboard which has onboard USB 2.0 and 3.0 controllers. If I connect an external USB 3.0 hard drive to one of the USB 2.0 ports, the system recognizes it almost immediately and it is available to assign to a VM. If I connect the same drive to a USB 3.0 port, it is never recognized and I cannot use it. I have the VM set to use the 3.0 (qemu XHCI) USB controller. I can see the controller is recognized by the system when I run "lspci | grep USB", but the external drive doesn't show up in the output of the lsusb command. Am I missing something? How can I get this to work?
