SOPC Component for ISP1362

Hi,

I am using the SOPC builder to generate a NIOS II with JTAG_UART, SDRAM_CONTROLLER and a ISP1362. I cam across the following file in this forum.

http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/usbhost/isp1362_ctrl.v

After generating the processor, the synthesizer fails. I think the reason is that OTG_DATA is of type "inout" and readdata is type output. Im getting this error:

Error: The node "nios_system:NiosII|ISP1362:the_ISP1362|ISP1362_CTRL:the_ISP1362_CTRL|readdata[7]" has multiple drivers due to the always-enabled I/O buffer "nios_system:NiosII|OTG_DATA_to_and_from_the_ISP1362[7]"

any help would be greatly appreciated.

Thanks
