[U-Boot] Doubt in USB driver for Vybrid vf610

[Santhosh Kumar Janardhanam -ERS, HCL Tech]

Hi All,
I am working on USB part for vybrid vf-610 processor, We have two ports in the board

when I type usb start in uboot command prompt, It returns as ENODEV for USB0 and when analyzed, It is returning from the below code in ehci-hcd_init function(in ehci-vf.c)

        if (init == USB_INIT_HOST && index == 0)
                return -ENODEV;

 If these two  lines are commented, the usb start is working and device is found on USB0. 
Why is this check kept in the code? 

Regards,
Santhosh
