F200 Camera Randomly Disconnects / Reconnects Most of the Time

[Chris_T_4]

Hello,

I just purchased an external F200 camera, and all of the drivers and the SDK appear to have installed correctly.  I have also installed all relevant WIndows updates, and my computer meets the hardware requirements.  What commonly happens for me is when I first run one of the sample SDK apps, it works properly (all depth/color/ir).  But as soon as I either run a new app or switch to a different resolution stream, the camera suddenly disconnects and reconnects (I hear the corresponding USB earcons), and initialization fails.

I have attached the logs of one of the runs that did the disconnect/reconnect.  Perhaps an engineer could look at them and shed light on the problem?

Many thanks, and please let me know if you need any more information

Chris, I looks like it was USB power supply issue. Could you try the different USB port? Thanks!

Thank you for the response!  I had a feeling that was the problem.  I have tried other ports but to no avail.  Are there any reasonably priced externally powered USB 3.0 hubs that you could recommend and that you know have enough power for this application

Thanks,

Chris

You maybe can try this one. http://www.amazon.com/AmazonBasics-Port-2-5A-power-adapter/dp/B00DQFGH80/ref=sr_1_4?ie=UTF8&qid=1448920103&sr=8-4&keywords=powered+usb+hub+3+0

Hi All,

Thanks to David's suggestion, I was able to get this working.  So to others that may be having this problem, that particular externally powered USB hub does the trick.

Thanks,

Chris

just a pondering question here...

The attached amazon link shows a hub to 4 10W USB3 ports, which is basically the minimum of the specs for a usb3 (there are 10W. 36W, 60W and 100W version) . And from what i saw there is no external power source - it is powered by a usb3 cable. 

So why would it work on the usb hub and not on the usb port itself?

Hi Yiannis,

The hub actually does have an external power source.  If you look at the third picture in the preview on Amazon you can see it.  Hope that answers your question

Thanks,

Chris
