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?
I can give it a try. Do you have any patches to enable the VBUS regulator on omap5-uevm?
I think everything is already upstream and I have not used a special patch for it. See extcon_usb3 and &usb in omap5-board-common.dtsi. This seems to connect the ID pin to the smps10.
The dwc3 role patch is also upstream
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h...
so that it should work out of the box for USB2 (or 3) with mainline kernel Unless I did miss something important I am not aware of.
I think I found the problem.
Can you please try with the below patch? Super-speed host works for me [1].

At least the mesaage about the bad USB cable is new. So the patch has some effect.
What I am missing is something like
[ 115.203304] omap-dwc3 4a020000.omap_dwc3: mailbox: VBUS valid
This was from my local debug patch so you won't see it.
Maybe this is just different on the Pyra. We do not use the SMPS10 but an external bq24297 with an out-of tree driver we have hacked together and it might have to send some mail.
Were you able to get High-speed devices working on the xhci port?
