Hello community,

 

I have one question about errata No. ERR010822 in document of IMX6DQCE Rev 7.

It say that, this problem will be occur 

   "when two or more hubs are between the USB host and device."

 

The other hand, it say that

The issue does not occur

    "without a hub connection"
 because there are no additional bits after EOP.

 

If it have one hub connection between the USB host and device, 

This errata will be occur or not?

 

Is it meen that

 "without a hub connection"    = one root hub

 "when two hubs connection" = one root hub + one additional external hub

correct?

 

Best regards,

Ishii.
