I am using pyusb in my Python 2.7 environment getting the status of the Zebra KR403 printer and having good success on a Windows 7 64 bit PC. Now I am ready to test this on my target machine. I have created my executable program with py2exe and tested the exe on my development PC and it works fine but when I move it to my target PC I get a message "No Backend Available" when it gets to the "dev = usb.core.find(idVendor=int(VID), idProduct=int(PID))" part of my code. I convert the hex to an integer here but when using the hex value I get the same issue on my target PC, even with hex value, both hex and converting to integer work fine on the development PC so I do not think the issue is here.
Traceback (most recent call last): File "ZebraKR403PaperStatus1.0.py", line 98, in <module> File "usb\core.pyc", line 846, in find ValueError: No backend available I am not sure what is causing the issue. It seems as though there is a missing dll or something that is required to make this work and it did not make it to my target PC. Any suggestions or ideas what I may be missing would be greatly appreciated. Jay
