OTG issue with a USB3 device

[rosietastic]

Hi all,
I am a long time lurker and a very proud owner of a Pyra.
I am trying to get a USB3 storage device (Samsung ssd) working with the Pyra using a USB OTG cable and cannot get it to work.
The device works when plugged directly into the Pyra USB2 port.
Also, it works fine using the same USB OTG cable on a Samsung Note3 (with a Phronesis Android Rom).

Syslog shows the following when I plug the OTG cable in to the Pyra with the device connected :

Any ideas on what I can try?
Apologies in advance if I am doing something daft here!

I could get a mouse to work on this port, but anything else seems to puke, I suspect there may be a need for an externally powered USB 3 hub to utilize anything that draws more than 100mA

Maybe the USB cable is bad?

 

[TrashyMG]

I suspect these OTG ports are not designed for devices, so they limit the current draw on them, which I think running an externally powered USB hub may do the trick. I'd need to test it out.

Understood, thanks.
The OTG cable includes a standard USB for additional power too, but that is not helping. Will try again and get a hub also.

Thanks. Have tried different cables to no avail. These cables work on my Note3 as well.

Cross-linking:

Both full size USB ports not working

I've tried pluging in different stuff but nothing happens. Here is dmesg from booting up with grep usb. [ 0.000000] Kernel command line: root=PARTUUID=efca4260-02 console=ttyO2,115200n8 console=tty0 vram=12M omapfb.vram=0:8M,1:4M omapfb.rotate_type=0 omapdss.def_disp=lcd rootwait...

True, but this thread is about the micro-USB3 port as far as I'm aware. The two full sized type-A ports are different things. It's worth having these threads linked I guess, but that distinction should be noted.

Agreed. Both threads could be related; my original post is regards usage of the micro-USB3 port with an OTG cable.
The ssd storage device does actually work when directly connected to the full sized USB2 ports (and doesn't need additional power).

Tried additional 2A power via the OTG cable using the micro-USB3 port, but am getting the same results. Annoyingly, I don't have a powered USB3 hub where I am at the moment to test.

Thanks for your help on this.

I'm don't appear to have any issues with my regular full sized USB ports, but I've only tested a small handful of things.

Yeah I lack a real powered USB 3 hub myself. I may get one eventually.

Real powered USB 3 are for real men.
