Powered USB Hub Not Recognized

I just received the replacement for my Aero Board and Vision Kit. The first one didn't recognize the cameras. This one doesn't recognize the powered USB hub, but the first one did. The image is the shipped default bios of 1.00.03, OS is Linux version 4.4.3-yocto-standard and is dated Tue Aug 16 15:11:54 PDT 2016. A keyboard works if I plug into the USB OTG port adapter cable directly, but then I only have a keyboard and can't update the image. Any ideas? I'll try a different powered hub today too.

I tried a different powered USB hub, and also a different OTG cable, no luck. So I'm dead in the water.

Hi PureRockets,

 

 

Thank you for contacting us, we'd like to help you so you can work with the Aero Platform.

 

The behavior you get is strange, if the USB hub is powered, then it should recognize other devices you connect to the Aero. If you plug other devices such as a USB mouse of flash drive, do you see them get recognized? This is to make sure the port is working correctly.

 

 

We'd also like to take a look at the connections, could you attach a picture of the USB hub connected to the board and to the other devices. Also, what USB hub model are you using?

 

 

Another thing that's important is to review is that is necessary to follow the Getting Started Guide https://github.com/intel-aero/meta-intel-aero/wiki/Quickstart-Guide https://github.com/intel-aero/meta-intel-aero/wiki/Quickstart-Guide . Here you'll find all the prerequisites needed before connecting the USB hub.

 

 

We'll be waiting for your response.

This same USB hub worked with my first Aero board. I also tried with a second hub, no luck. The hub can only connect one way via the supplied adapter cable, with the keyboard and mouse then connected to the hub. Here is the https://www.amazon.com/SuperSpeed-Support-Charging-Sy-Hub20152-SY-HUB20152/dp/B00KNO7NS0 USB 3.0 hub that is not working. A keyboard alone works as expected when connected to the adapter, but does not work when connected via the hub. I haven't had these issues with the Intel Edison, Intel Galileo, nor the Intel Joule which all work great.

I think what I will try to do is automatically run lsusb >> usb.log on boot when the hub is plugged in. Since I won't have a keyboard connected, it's the only way to see if the system recognizes the hub. I can then plug in the keyboard, boot again, and view the log file.

One thing you can try is to upgrade the BIOS. There's a newer BIOS released that the 1.00.03 version you're using. If you look at https://downloadcenter.intel.com/download/26500/UAV-installation-files-for-Intel-Aero-Platform https://downloadcenter.intel.com/download/26500/UAV-installation-files-for-Intel-Aero-Platform you can see the necessary files you need to download and a link with instructions to update the BIOS. If you receive an error, please post the full error log.

 

 

Try this approach and let us know if it worked.

Upgrading the BIOS is not possible without a hub. You need a minimum of two USB ports, one for the keyboard, one for the USB drive. I can't upgrade the BIOS with the single USB port.

Hi PureRockets,

 

 

Thank you for the clarification. It's hard to say what could be the issue. From all that you've posted the problem doesn't seem to be with the hub hardware itself since the first Aero board recognized it. The Aero's port can recognize other devices so there's no hardware damage and you've used other USB hubs and cables.

 

Did you have a chance to look at the log file to see if it provides any clues? Make sure the Aero board is being supplied with the proper voltage and please attach a picture of the USB hub connected to the board as well as to the power supply.

 

 

We'll be waiting for your response.

Hi PureRockets

 

 

We were wondering if you managed to use your Aero board with the USB hub. Please let us know if you still need assistance with this case.

Hi

I just received a new Aero RTF kit, and I have the same issue in that a powered USB3 hub is not recognized

Things that work:

a. System boots, and HDMI drops to shell

b. WiFi AP works

c. Most importantly, connecting via the USB3 port to another linux machine works; I was able to transfer the updated bios and flash over the USB cable, but the hub is still not recognized.

d. Directly connecting USB peripherals also does not work.

It almost seems like the USB controller is stuck in OTG mode? Any help will be greatly appreciated!

Hi icoderaven,

 

 

Have you tried to use different USB cables and a different USB hub? When you connect a device to the hub, is it recognized by lsusb? Please post a picture of the output of lsusb.

 

 

We'll be waiting for your response.

Thanks for responding!

lsusb does not recognize the hub, or any device I directly connect to the port, except when I connect the aero to my laptop, when it registers as a RDNIS device over OTG.

Is there any known good hub that I can try ordering?

Hi icoderaven,

You're welcome, we want to help you resolve this issue. What I can do is let you know the hub we use for our tests, where your issue doesn't happen. You shouldn't consider this as the official hub that Intel recommends, but, as one that has worked for our personal tests. We use a Sabrent 4-port USB 3.0 Hub with power adapter.

Hopefully, you can find this information useful.

That's useful, thanks! I understand re: it not being the official hub that intel recommends.

Also, could you also tell me what micro USB3.0 to Female USB3.0 converter you use?

Hi icoderaven,

 

 

To connect the Aero board to the hub we used the USB OTG cable that comes included in the kit. We connect the micro B end of USB OTG cable to USB 3.0 OTG port of the board and the other end to the USB hub.

Ah, the RTF kit didn't ship with one. I'll order one in the meanwhile!
