Convert DZCOMM to LibUsb

The [login to view URL] open source software (<[login to view URL]>) uses the DZCOMM library for its serial communications.? However, many newer hardware devices connect to the PC via USB.? The code (latest is 1.13) needs to have the DZCOMM library calls replaced with calls to the libusb (<[login to view URL]>) library. I can provide any details about an example USB device it needs to communicate with.? This is not a commercial project and the code will be released under the GPL in line with the original software.? I am focusing on running this under Linux.? The software also needs the allergo library to compile.
