BF527 EZ-Kit Lite USB OTG

I have been using BF527 EZ Kit Lite 1.4 to test my USB OTG (Host) code. This communicates with a USB device through OTG connector. Everything was working fine till now. Suddenly something went wrong and...communication is not happening between EZ-Kit Lite board (running my USB host code) and external USB device.

Upon debugging the host code I see that Host is unable to complete even the enumeration process. Do not know what went wrong.

I observed that VR3 (ADP3336ARMZ) on the EZ-Kit Lite is getting over heated when USB device is connected. Is it normal or... has it gone bad...

Please guide me in debugging the issue....


Thanks and regards.
