Problem using multiple USB modems

[terrybbarton]

I have a Mac OS X host with an Ubuntu guest OS and a couple of Huawei E220 USB modems attached. I need to have one modem always stay attached the the guest as ttyUSB0 and the other always stay attached ttyUSB1. They sometimes trade places. I tried to set up USB filtering but I guess I don't understand it well enough on a Mac.

VBoxManage list usbhost
gives me:

Does anyone know how to create a filter or what I would need to do to keep these devices always on the same USB port in the guest OS? I am a noob with VirtualBox so I don't understand how it handles USB very well yet.

The solution I found was to recompile my software for Mac OS X and run it directly on the host instead of through VirtualBox. Works great. I hope VirtualBox's USB support gets better.
