Dear TI,
I am using TUSB7320 (EVAL board) with dart MX6 freescale based chip from variscite and these are the errors I am getting (See below).
It works with renesas chipset usb 3.0 hub but not with TI TUSB7320 chip, Could it be a driver issue? is there a specific driver that works with these chip or should it work just with the default installed driver? (TUSB7320/TUSB7340)
Please Help,
Regards

On the black board it's the TUSB7340 that I am using on my design,
I've also took a picture of the Eval board that I got to test the TUSB7320 where we were able to replicate this issue while using the iMx6 Processor.
Also to answer the question yes we have tried with different usb drives. same issue...
The detection issue happens every time we put a USB 3 stick...it reset and tries to mount until it give up trying...
