some of the BSP (like CEPC) while perform a SoftReset, the system will not
trigger a Reset Signal to the peripherals.
So maybe your USB Host controller can not be funtional without a Hardware
Reset Signal.
Some of the work around is to perform a reset for your USB host controller
while loading driver or before soft-reset

> I am working on a USB Interface. I have a USB Device, the driver is
installed properly when I connect my device for the first time. I am giving
a soft reset without removing the device from the USB Port(meaning the
device is plugged in when I give a soft-reset).

all i am making a mistake in thedriver which exposable function in the DLL
shuld i peep into. Is it XXX_Powerup?
