RM48 hdk USB power TPS2552 on schematic (Development KitTMDSRM48HDK) - Wrong part

Hi,

I apologise if this is not right place to place this question / discussion.

On development board, TPS2553DBV is fitted (using same parts), while schematic symbol shows TPS2552DBV. 

The design with TPS2552DBV was tested and it did not work, as we could not power the USB device.


Examining the development board we noticed that TPS2553DBV was fitted not TPS2552DBV  as per schematics.

Replacing TPS2552DBV with TPS2553DBV has fixed the problem.

Bug is in the fact that TPS2553DBV has EN as active high, while TPS2552DBV has EN as active low.

Can someone confirm this is the bug in the schematic.
