Device Recognized but will not boot

zippyzoo77

Hello,

I am having trouble getting my OAK-D to connect to my computer so that I can use it through ROS as a part of my research into underwater robotic SLAM. I have tried several different methods of trying to get the camera to work over the tether (100m), and I think the closest I can come is to use a pair of adapters from usb2 to ethernet, then back from ethernet to usb2 on the topside. However I am having trouble getting the camera connected through this setup. I am using the usb2 mode for sure, since I only have 3 of the 4 pairs available in the tether, but before I mess with that part I am just trying to connect the camera over a shorter ethernet cable with the adapters.

When I run lsusb | grep 03e7 I get
Bus 003 Device 097: ID 03e7:2485 Intel Movidius MyriadX

When I run dmesg -w then plug in the camera, I get:
[442896.307338] usb 3-11: new full-speed USB device number 98 using xhci_hcd [442896.435438] usb 3-11: device descriptor read/64, error -71 [442896.693182] usb 3-11: New USB device found, idVendor=03e7, idProduct=2485, bcdDevice= 0.01 [442896.693194] usb 3-11: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [442896.693198] usb 3-11: Product: Movidius MyriadX [442896.693202] usb 3-11: Manufacturer: Movidius Ltd.

When I run roslaunch depthai_examples stereo_inertial_node.launch I get:

When I run python3 depthai_demo.py -usbs usb2 I get:
Using depthai module from: /home/smartslab/.local/lib/python3.8/site-packages/depthai.cpython-38-x86_64-linux-gnu.so Depthai version installed: 2.20.2.0 Setting up demo...

I know that the cabling is working, as other usb devices I have plugged into it have worked just fine (controller, mouse, flash memory stick), and I'm really stumped as to where to go from here, since the camera is being recognized, it just won't actually run. Could anybody help me with this please?

Hi zippyzoo77 ,
Could you describe a bit better how you are doing this?

adapters from usb2 to ethernet, then back from ethernet to usb2 on the topside

Perhaps some photos / url of products you are using would be helpful.
Thanks, Erik

This is the adapter I am using. It seems to work very well for all sorts of other usb products, only the OAK-D is having troubles.

Hi zippyzoo77 ,
Interesting, I wasn't aware of that. What's the length of the cable you are using? I assume it could work up to about 3m. Customers have been able to achieve longer cables only with either POE (should be up to 100m iirc) or active USB cable. Thoughts?
Thanks, Erik

The specs on the adapters say it should work up to 150 ft, the cable I have that I am testing with now is 14m (I tried a 3m cable too, but it didn't change anything). I've tried it with just about every device I have in the office (xbox controller, iphone, mouse, flash drive) and it seems to work with everything except the OAK-D. Maybe it could be something with the speed being lower? I'm just really stuck as to why everything else works, but not the one thing I need to work.

With the POE cameras, do they require all four pairs of the ethernet cable? I only have three available to me, which is why these adapters are what I went for since they only actually use three pairs, the other pair is just grounded out.

Hi zippyzoo77 ,
Could you also try a shorter cable, eg. 20cm one? Different devices use different protocols over USB, which might be more or less robust.
I believe that for 1gbps speeds you need all 4 yes, not sure whether you could use less and get only eg. 100mbps link. Maybe create an issue on depthai-core wrt this question.
Thanks, Erik

zippyzoo77

The shorter cable did not change anything either

erik

Hi zippyzoo77 ,
Interesting - it does work with the standard USB cable though, right? Which connections on the USB are you missing (with the 1 pair that's missing on the eth cable)?
Thanks, Erik

zippyzoo77

With what I'm testing right now, I have all the pairs. On the end version I will be missing one of the pairs, but when I crimp the connectors on the end I can choose which one it is. The adapters have the middle two pairs grounded out, so my plan was to have one of those pairs be the missing one.

And yes, the camera works fine with both usb3 connection and usb2 connection through standard cables.

Hi zippyzoo77 ,
Good to know, thanks for elaborating. I think the best option would be going with PoE, and by removing 2pairs getting the 100mbps link. Thoughts?
Thanks, Erik
