Downgrading USB 3.0 controller to USB 2.0

Postby plastichairball » Mon Nov 14, 2016 15:44

Hi all, I've got a Fujitsu Esprimo Q556 and I wanted to know if it's possible at all to downgrade the USB 3.0 Xhci controller to USB 2.0
I am trying to attach 33 cameras and running up against the USB 3.0 limit and I can only get 18 or 19 at a time.

I've tried older drivers and trying to turn on Ehci mode in the Bios but that didn't work and there was no option like that respectively.

Any help would be greatly appreciated!
