eXtensible Host Controller Interface Specification(rev 1.1), 4.6.6:

"A0 shall be set to ?1? and refer to section 6.2.2.2 for the Slot Context fields
used by the Configure Endpoint Command."

But in function 'xhci_configure_endpoint' or 'xhci_setup_ctx'  A0 not set to '1' state.
On hardware it work normally, but not on qemu emulator.
>How-To-Repeat:
I have seen that when I run netbsd on qemu with the usbhost named nec-usb-xhci.
>Fix:
Enable SLOT Context. A0 shall be set to '1' in xhci_configure_endpoint or xhci_setup_ctx function
