Thank you Jochen
My usb device hat already a driver and a commuincation protocol from the original company and this protocol says that I can use Windows function Createfile...with the driver to accsess the device
the other option for me is to use libusb (because winusb is hard )
I will try this way.

because when I use Writefile directly after Createfile I have the error E0001009 USBIO_ERR_NOT_BOUND

Thanks Rick
sorry to be late but i was really basy last time:
So You are Right there is a problem with pipe issue :
So I think I have two choises : Createpipe() or CreateNamedpipe();
I have tried Createpipe().. then Writefile() and Readfile() are working without Errors but the device has no reaction.
With CreateNamedpipe() how can i use the usb path to creat the right pipename ?
