RE: xhci data toggle out of sync

Hi HPS,

The error seems to be NO_PIPE and end points are 2 & 3 but the 
usbconfig dump_all_desc lists epaddress 1, 81 any idea why ?

Is there a chance you can find out why the XHCI controller is not accepting these commands?

I mean, if the endpoint cannot be reset, also when there is no previous failure, there clearly is a design issue in the fabric :-(
