[Qemu-devel] [Bug 1579306] Re: usb-uas does not work in Windows (10) guest

[Jack Coulter]

Just echoing Tom Yan's comment; I've tried passing through what appears
to be the very same device (if not, at least the same UAS-SATA bridge)
to a VM in its entirety.

I can confirm the same result - with an otherwise identical domain
configuration, Linux guests correctly use the UAS driver:

/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 5000M
    |__ Port 1: Dev 2, If 0, Class=Mass Storage, Driver=uas, 5000M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 480M


Whereas Windows guests fall back to BOT/MSC:

In both cases, QEMU is being run via libvirt, which is generating the following 
command line:

Title:
  usb-uas does not work in Windows (10) guest

Status in QEMU:
  New

Bug description:
  When I attach a "-device usb-uas" to a VM with Windows 10 10586, the
  device fail to start with the following error in the guest:

  "The device cannot start. (Code 10)

  {Operation Failed}
  The requested operation was unsuccessful"

  If the host controller is nec-usb-xhci, there will be two of the
  following error on the terminal of the host as well:

  "qemu-system-x86_64: usb_uas_handle_control: unhandled control
  request"

  If it's usb-ehci, ich9-usb-ehci1 or ich9-usb-echi2, this will not show
  up on the host side, but the device stil fails with the same error on
  the guest side.
