I think they are two separate issues in usb-uas and usb-host
respectively. I probably should not have bring in the usb-host case here
but create another report for it.

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.
