No matter what I do can't get my drives working at USB3 speeds. Everything looks right, so I am hoping some other eyes can give me some hints.

Code: 
  # lsusb
    Bus 004 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
    Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 001 Device 004: ID 1058:25a3 Western Digital Technologies, Inc. Elements Desktop (WDBWLG)
    Bus 001 Device 003: ID 04e8:61f5 Samsung Electronics Co., Ltd Portable SSD T5
    Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
    Bus 002 Device 002: ID 1a2c:4324 China Resource Semico Co., Ltd 
    Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

It shows the USB 3.0 hub

Code: 
  # lsusb -t
    /:  Bus 04.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M
        |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/8p, 480M

            |__ Port 4: Dev 4, If 0, Class=Mass Storage, Driver=usb-storage, 480M

dmesg shows me

I have tried plugging in every port and I only get USB2. What am I missing? The controller is there but some option is not enabled? I'm baffled. This is PVE 6.3 on the no-sub repo to latest/greatest. Thanks all!
 
maybe there is an unused usb3 header on the mainboard? can you tell us the model of the mainboard/server?
i assume you talk about the host and not a vm, right?
 
Yes, this is the host. I didn’t know if USB ran the hubs in parallel or they were physically separate. In copious digging, USB hubs are not linked - which may seem obvious to everyone but me.

I think this is a hardware/physical issue and not OS at this point. Appreciate the reply - but I’m off to look at jumpers and BIOS settings.
