The log shows:
-->STALL: t 41042a, req 00000000
Which means: ep->responded is 1.
Does this help?

Another observation:
Running the netchip test14 with Intel 82801GB EHCI controller does not
show PING being sent after a NYET response.

So its not clear what the Host behavior is after it gets a NYET?
Is there an existing EHCI that has this behavior?
