i use vs2011 to develop WDF driver. i used Template created a USBdriver and i just add a kdprint function in the begin
of DriverEntry.

Then i build it and i install the driver in a target machine(winxp) which is a VMware virtual machine . On the target
machine i use EzDriverInstaller install the driver and it shows 'the driver load successfully'
.
but i can't receive kdprintex message in the windbg which run on the host (win7). the windbg just receive message from WdfCoInstaller01009.dll.
