Windows: you can pull USB information from WMI, but you need to be administrator. The examples are in .NET, but you should be able to use the Python WMI module. This will give you access to USB identification strings, which may contain useful information. For FTDI serial devices there is a short cut using FTDI's DLL, which does not require privileged access.

Linux: all the available information is under /sys/bus/usb, and also available through udev. This looks like a good answer.
