Atom E38XX - USB mass storage device issue

[APadm]

Hello All,

We are using Atom E38XX on one of our product, we need USB mass storage device / Pend rive should work with 3 to 4 mtr cable length. ( we need at least one or two port)

As of now its working fine on only one port (USB_DP3 & USB_DN3), remaining ports are not working beyond 1 mtr. Low speed devices are working fine on all ports with 5 mtr cable.

We have taken cake of PCB trace length & its diff pair matching, Common mode, ESD, Shielded cables...

Kindly request you all to provide your valuable suggetions / Feedback

Thanks in-advance.
