Enterprise Home Screen v2.0 not working



I'm trying to use Enterprise Home Screen v2.0 in a Motorola TC55 (Android v 4.1.2) handheld but i'm not able to add applications to user screen. In admin mode home screen i press long the application icons untill a confirmation dialog appers, then i press ok. But in user home screen i don't see any application i before had added.

Reading doc : "Enterprise Home Screen is configured via an xml file found in the /enterprise/usr/ folder in the internal memory of the device. This file is read each time the User or Admin screen comes to the foreground."

But in my case folder /enterprise/usr is empty.

What am i doing wrong? Can you help me please? Thank you.
