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

I can give it a try. Do you have any patches to enable the VBUS regulator on omap5-uevm?

At least on dra7-evm I had a lot of trouble with many of the 3.0 OTG cables. The one I have working doesn't ground the ID pin. But I can use the J10 jumper to manually ground ID on the omap5-uevm.
Is there a fix?

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.

At least the mesaage about the bad USB cable is new. So the patch has some effect.
What I am missing is something like

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.

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?

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.

No, they simply don't appear in lsusb besides the above shown log (unless I use an USB2 only cable where devices fall back to 480M) So I think the USB PHY recognizes that there is a device and also that there is an USB3 cable - but can't establish communication.
I have never seen something like:
[ 115.626660] usb 4-1: new SuperSpeed Gen 1 USB device number 2 using xhci-hcd
Maybe the cable is really bad.
I still have to do the test with the OMAP5EVM.

I stil could not get more than on the Pyra (haven't tried on OMAP5EVM yet):

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.
Ah, I see. Maybe I should add a similar debug command...
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?
No, they simply don't appear in lsusb besides the above shown log (unless I use an USB2 only cable where devices fall back to 480M) So I think the USB PHY recognizes that there is a device and also that there is an USB3 cable - but can't establish communication.
I have never seen something like:
[ 115.626660] usb 4-1: new SuperSpeed Gen 1 USB device number 2 using xhci-hcd
Maybe the cable is really bad.
Yes, that looks like the case. It is pretty hard to get a proper USB3.0 OTG adapter.
I still have to do the test with the OMAP5EVM.
Worth a try.

I have now tested with OMAP5EVM and still no USB3 speed or device. So it is most likely the OTG adapter cable.

Is your adapter blue in colour?
The adapter I have looks like this https://images-na.ssl-images-amazon.com/images/I/21aqpGAu4JL.jpg
I think the blue ones are the good ones.
I'd try one of these https://www.kabelbude.eu/product/computer/usb-stecker-adapter/usb-3-0-adapte...

Yes, sure. I also have a white one (with small µUSB plug) which works, and this type of blue ones which do not even work in UBS2 mode...
It is this:

Well, it seems to have two plugs on both ends. But they might also have the right combination (plug + socket).
Ok, I definitively should try a different one... Maybe the additional cable between the micro and standard ends makes a difference.
BR and thanks, Nikolaus
