Is this a new issue with the latest changes or was it there in the last release as well? And is only when the thumb drive is in the upper...

Actually I didn't know it, but the upper USB port always worked with high speed devices, the bug only effected full speed and low speed devices. I'm assuming your thumb...

Boy that was not I wanted to hear, so a regression then! I did merge one change from my earlier USB stack attempt (which at least worked on the first...
