Can anybody clear me actually who creates URB for sending it to
device.. is it vendor provided functional driver or bus driver.
Let us take example of Mass storage device.. is URB created by
USBHub.sys or USBSTOR.sys. and when we load vendor driver for
particular vendor mass storage device then also, is usbstor.sys also
gets loaded and then who creates URB's for passing information to and
from device.
