Hi, I am using a Fujitsu R670-2 workstation with a D2618 Mainboard, two XEON X5680 CPUs and 64GB of ECC DDR2 RAM. Unraid 6.8.3 is installed. I use this workstation to run some VMs (OsGeoLive for some heavy calculations and MacOs). Everything is working as it should except several PCIe x1 USB 3.0 controller I added to the machine. Mainly to pass them trough to the VMs. As started in this thread ( CLICK ) I had some issues with one USB controller not working. I bought a new one ( CSL 4-Port @ Amazon), passed it through to the VMs and was happy as USB sticks seemed to work. Then I added some devices the USB controller. But nothing. These devices dont show up neither in unraid directly nor in the VMs when passed through. While booting the devices seems to be started correctly. Hub 9 seems to be for USB2 devices and Hub 10 for USB3 devices.

I would guess that "device descriptor read/8, error -110" is the main error, but I am no expert in fixing that. I had the same problem using only usb2 devices.
