2 years ago PnP drivers will install with no device present, but will not load until the device specified in the inf file is connected to the system. If you are just trying things out, there are other samples that do not require physical devices. 'echo' for example.

2 years ago thank you .... indeed today i have complited my first step based on 'keyboard echo' .... all well .... now i procede to grow ... but one day in the next i need to know how to simulate a physical device connection ... and more maybe in the future realize something that pass to the usb bus (or the 'responsable target') the VID and PID of the physical device

2 years ago Simulating a usb device is way too complicated to be of any use. You would be better off buying a simple usb dev board instead and use that for experimentation.

2 years ago thank you for your kindness .... but obviously every 'personal DEVICE IO controls' i will couldn't test .... i will think to a solution with arduino or something other
have a nice day and still thank you

i have compiled and installed and 'i don't know' if it work correctly (i can't use the WPP tracer) a base driver example ....
obviously it's based on a 'usb logic / stack' and in the inf it has a 'USB....' driver path
my question is.... like when a driver is installed but no one physical devices are plugged-in the driver icon will be not show in the graphical device treeview.... the installer don't show me any error.... except something in a log file (but the driver service is installed with 'start-request on demand' and maybe it's the reason
maybe i need to simulate 'a virtual plug' .... is there some app that simulate a physical usb device?
or how can i know if my driver is working well without using the windbg or the WPP tracer?
thanks for help
