you can fail any i/o you receive based on state. you have maintain your own state once there is a valid handle.

hi all,
I want to know that, after I get the VALID_HANDLE
from SetupDiGetClassDevs (do the handle with a USB
device), whether the driver can prevent the windows
to communicate with the USB device?
That is to say, can driver let windows to know
the USB device is connected on the port, but the
driver won't let windows to communicate with the
USB device?
.
