I have tried usb start command as per the doc/README.odroid
what I felt was is their some config option missing.

Last time I face similar issue for Odroid XU4

commit 1b108880e6433e398681785f51b2a2dca983cd1b
(usb: xhci: Fix vendor command error if the request type is
USB_REQ_SET_ADDRESS or USB_REQ_SET_CONFIGURATION)

Solve the tftp issue for r8153 on Odroid XU4.

so I feel some similar fix is needed for ehci accept only standard
address request.
