I am also facing this issue.

On further probing, I found out that usb-uas in Qemu doesn't support
"SET_SEL" control command due to which windows driver "uaspstor.sys"
couldn't complete the enumeration.

It is clearly mentioned in USB 3.1 specs that uasp devices should handle
two new control commands - SET_SEL and SET_ISOCH_DELAY.

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.
