The ao_libusb_receive.txt file is created by default if you build the DLL & LIB with the DEBUG_FILE define, and if you use a USB2 stick (specifically, it will be created when the receive thread for the libusb USB device is started). Since you are able to run the original DEMO_DLL and setup a master channel and transmit normally - this should generate the debug files. What version of Visual Studio are you using (we tried this on 2008 & 2010)?
It is hard to say at this point whether the issue could be related to your specific hardware configuration, drivers, or something else.
