This is what I get w/ sysctl hw.usb.ehci.debug=6 for the first cmd

Subsequent cmds fail similarly. I don't see the issue and don't
understand how to use the overlay qTD information to pinpoint the reason
the controller is rejecting the request.
This happens w/ either of the 2 USB ports (1 port / controller):
ehci0: <IXP4XX Integrated USB 2.0 controller> on ixp0
ehci0: [GIANT-LOCKED]
ehci0: [ITHREAD]
usb0: EHCI version 1.0
usb0: stop timeout
usb0: set host controller mode
usb0 on ehci0
usb0: USB revision 2.0
uhub0: <Intel EHCI root hub, class 9/0, rev 2.00/1.00, addr 1> on usb0
uhub0: 1 port with 1 removable, self powered
ehci1: <IXP4XX Integrated USB 2.0 controller> on ixp0
ehci1: [GIANT-LOCKED]
ehci1: [ITHREAD]
usb1: EHCI version 1.0
usb1: stop timeout
usb1: set host controller mode
usb1 on ehci1
usb1: USB revision 2.0
uhub1: <Intel EHCI root hub, class 9/0, rev 2.00/1.00, addr 1> on usb1
uhub1: 1 port with 1 removable, self powered
