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

[Tom Yan]

I am using qemu-2.5.1. Here are the commands I used in the test cases:

qemu-system-x86_64 -enable-kvm -cpu host -m 2G -net none -full-screen
-drive file=disks/uas.qcow2,format=qcow2,cache=none,aio=native -drive
file=test.img,format=raw,if=none,id=test -device nec-usb-xhci -device
usb-uas -device scsi-hd,drive=test

qemu-system-x86_64 -enable-kvm -cpu host -m 2G -net none -full-screen
-drive file=disks/uas.qcow2,format=qcow2,cache=none,aio=native -drive
file=test.img,format=raw,if=none,id=test -device nec-usb-xhci -device
usb-bot -device scsi-hd,drive=test

qemu-system-x86_64 -enable-kvm -cpu host -m 2G -net none -full-screen
-drive file=disks/uas.qcow2,format=qcow2,cache=none,aio=native -drive
file=/dev/sdc,format=raw,if=none,id=test -device nec-usb-xhci -device
usb-uas -device scsi-block,drive=test

qemu-system-x86_64 -enable-kvm -cpu host -m 2G -net none -full-screen
-drive file=disks/uas.qcow2,format=qcow2,cache=none,aio=native -device
nec-usb-xhci -device usb-host,hostbus=2,hostport=6

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.
