You need to tell us which USB port you are trying to use and also your command lines that shows the modules you loaded (need to do a modprobe ehci-hcd), dmesg output, etc.

Have you read the usb.pdf file that comes in the LTIB iso?

Also, can't  you use the latest rel6 BSP?

We are trying to access USBH1 .

We can use rel6. Could we download BSP rel6 ? If so,  could you provide the link, if you know...

Please find below the details

You can download the latest MX31ADS Linux BSP from here: http://www.freescale.com/webapp/sps/site/overview.jsp?nodeId=02VS0l320822D0033202A7

Take a look at the usb.pdf document that comes with the ISO.

The correct command is: modprobe ehci-hcd
