Hello, Ananth.PN :
Thank you for contacting Intel Embedded Community.
In order to be on the same page, we would like to address the following questions:
Could you please let us know if the affected project has been developed by you or a third party company? In case that it is a design from other company, please provide us all the information related to it.
On the other hand if it is your design, could you please confirm if it has been developed following the USB guidelines and suggestions stated in chapters 15 and 16, on pages from 210 to 245 of the Intel(R) Atom(TM) Processor E3800 Product Family Platform Design Guide (PDG) document # 512379? On assumption that this document is inaccessible to you, please update your EDC account. To learn more about the benefits of an EDC Privileged account go to http://www.intel.com/content/www/us/en/embedded/embedded-design-center-support.html. Then click on “APPLY NOW” found under the heading, “Apply for extras with privileged access to the Intel EDC¹”.
Finally, could you please verify as a reference that your implementation fulfills with the answers of the USB FAQs specifically the Cables and Long-Haul Solutions section?
Please let us know all the information requested through the previous questions.
Thank you for your speedy response,
Yes, its our own product designed by us.
We have EDC account as well & we have followed PDG USB guidelines during our product design.
Still we are facing this USB Mass storage device detection issue with USB cable beyond 1mtr, except one port (USB_DP3 & USB_DN3 with USB2 Data Switch TS3USB221A-Q1 ).
Hello, Ananth.PN :
Thanks for your update.
In order to have a better idea of this situation, could you please tell us how many units have experienced the cited condition and how many have been manufactured?
Could you please tell us if this project has been verified by the Intel Design Review Services? In case that your answer is negative, please follow the procedure stated at the Intel Design Review Services website and let us know the results.
Waiting for your answer to the previous questions.
