'Clear endpoint halt failed' FRDM-KL25Z HID during compliance tool test

[bobpaddock]

I'm trying to bring up a Generic HID (this is not a keyboard or mouse) on the Freedom Board FRDM-KL25Z, Kinetis MKL25Z128.

Has anyone else used, or run into problems with the USB Consortium's Command Verifier Tool, USB20CV R1.4.9.7,  against Kinetis parts?

http://www.usb.org/developers/tools/

When I run the USB 2. 0 Command Verifier tool on Windows7x64 I always get:

"ERROR   Clear endpoint halt failed".  Other tests always pass.

I'm hoping someone here can shed some light on why this test is failing the compliance check.

I've included a bus capture and the setup_endpoint() code below.

These Halt tests take ten seconds to run, while all the other tests take one second to run.

This seems suspicious to me.  Is it normal for this Halt Feature test to take so long?

Below is three test runs of the Halt Endpoint Test, in Command Verifier.

First run is code returning the current status of the Halt bit, as the code should work.

Second run status always returns zero, and the third run status always returns 0x0001, to prove that changing the code changes the test results.

Clear_Feature(ENDPOINT_HALT) is being done in SetConfig and SetInterface per the USB 2.0 spec.

Doesn't matter if the USB0_ENDPT() is commented out or not, results are the same.

Any insights?
