USB 3 disco rígido e placa não funcionando no modo super velocidade

Question

Então, eu recentemente adicionei um cartão USB3 ao meu computador, e achei que tudo estava bem, o Linux detectou, embora estranhamente (ou não?) ele aparece como dois hubs

[    2.086988] xhci_hcd 0000:07:00.0: xHCI Host Controller

[    2.092566] usb usb2: SerialNumber: 0000:07:00.0

e

[    2.092881] xhci_hcd 0000:07:00.0: xHCI Host Controller

[    2.096116] hub 3-0:1.0: 4 ports detected

isto é similarmente visto com o lsusb, onde mostra os dois dispositivos sendo manipulados pelo xhci

/:  Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 5000M
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 480M
    |__ Port 3: Dev 5, If 0, Class=Mass Storage, Driver=uas, 480M
    |__ Port 4: Dev 6, If 0, Class=Hub, Driver=hub/3p, 480M
        |__ Port 1: Dev 11, If 0, Class=Mass Storage, Driver=uas, 480M

e, portanto, o problema, meu disco rígido USB3, que relata o suporte a superspeed está conectando somente ao hub usb2 (de alta velocidade?).

isso também é mostrado no dmesg

quando conectado, vejo

[538663.101097] usb 2-4: new high-speed USB device number 6 using xhci_hcd

lsusb -v para o disco rígido externo mostra que ele suporta super-velocidade

  SuperSpeed USB Device Capability:
    bLength                10
    bDescriptorType        16
    bDevCapabilityType      3
    bmAttributes         0x00
    wSpeedsSupported   0x000e
      Device can operate at Full Speed (12Mbps)
      Device can operate at High Speed (480Mbps)
      Device can operate at SuperSpeed (5Gbps)

então estou com uma perda de como proceder. Meu cartão está com defeito? O Linux está fazendo algo errado? De qualquer forma para forçá-lo a usar o outro "hub"?
