Try disabling the USB controller or hub and enabling it back.

the system should always detect that you plugged in a device. are you
saying you physically remove the device and insert it again and the OS does
not find it?

the os can always find it.i don't mean that.
because i am writing a program that can eject the usb storage device
from os.for testing it,
i must physically remove the device and insert it over and over again,
this operation is so trouble
so i decide to write a program that can simulate this physcial
operation.
trying shatskih's method , it can solve that problem .but there is a
new problem that the usb mouse device is disabled.
how can i distinguish the usb storage device from other usb device
when disableing the USB controller
