1BADRR Posted September 9, 2019 Share Posted September 9, 2019 I am sure I am shooting in the wind but ALL of my usbs are in group 3 I have tried every single usb and all of them keep ending up right back in IOMMU Group 3..... can anything be done? Quote Link to comment
Squid Posted September 9, 2019 Share Posted September 9, 2019 (edited) One of the ACS override options in vm settings. If none of them help then nothing you can do unless you can move a controller to a different slot Edited September 9, 2019 by Squid Quote Link to comment
1BADRR Posted September 9, 2019 Author Share Posted September 9, 2019 Of course it didn't work. Thanks for your reply. Quote Link to comment
JonathanM Posted September 10, 2019 Share Posted September 10, 2019 15 hours ago, Squid said: nothing you can do unless you can move a controller to a different slot And the different slot may mean in a whole different motherboard. IOMMU groups are dictated by the motherboard design. That's the primary reason for searching out someone who is currently running what you are trying to achieve, and copying their build exactly. 1 Quote Link to comment
1BADRR Posted September 11, 2019 Author Share Posted September 11, 2019 @jonathanm @Squid I used the ACS override in multiple configurations in conjuntion with my Bios xhci settings to try to break the group up and force the USB devices onto another controller with no success. I wonder, could you flood the controller by attaching external USB hubs abd filling them with random usb components (in this case IOMMU group 3) and cause the mobo to reassign the "over flow" onto another buss? Just a thought. I am a newb so. Quote Link to comment
Squid Posted September 11, 2019 Share Posted September 11, 2019 Doesn't matter how many devices you put onto the controller. The controller's IOMMU group will not change with your current hardware. Quote Link to comment
