USB3-OTG on OMAP5EVM (and Pyra)

Hi, I finally got some USB3 OTG cable (said to be compatible with Samsung Galaxy Note 3). Unfortunately devices do not enumerate (don't show up in lsusb -t) and don't even fall back to USB2 speed. If I use a pure USB2 OTG cable all devices work in USB2 mode.

This is all the same on OMAP5EVM and Pyra.

Is this known or does USB3-OTG work for someone? Is this repeatable or just a problem of my setup (e.g. bad cables)? Is there a fix?

BR and thanks, Nikolaus
