I'm new to this, so I apologize if my question is uneducated:
I have a USB device for which I know the ProductID and VendorID.  From what I understand, it should be a HID device which sends a serial stream to my computer.  I was to write a script in python in order to read that serial stream, but I am getting nowhere.  Is there a way for Python's serial library to find a device from a PID and VID?
You can also just do an 'ls /dev/tty*.*' and find the USB device rather than go through to voluminous amount of garbage dumped by 'ioreg'.
