OMAP USB & Zoom (LogicPD) kit USB Ports (HOST & OTG)

Hi,

I am using Zoomkit LogicPD-EVM) with OMAP 3530 & TWL4030 chip. The EVM has two USB ports, 1) HOST (Type A) - OMAP HSUSB2 and 2)OTG(Mini AB) - OMAP HSUSB0.  Iam not using the linux kernel drivers, we are using our own code running on threadx OS & filex, usbx stacks. Iam facing the following issues with the EVM which I absorbed across all the 3 kits we have.

OTG - Cannot able to do bulk transfer/read more than 512 bytes on/from mass storage device.

HOST - Can able to detect USB - Mouse & Keyboard, but cannot able to detect mass storage device.

The EVM kit uses ISP1704AET device for HOST & TWL4030 for OTG interface.

Anybody can help me in finding solution for these issues? I heard that OMAP HSUSB0 - host doesn't support mass storage device??!!!

Thanks in Advance,

Yuvaraj V
