4 How do I know what my deviceID is?
Launch the System Profiler utility, or Apple System Profiler for earlier versions of OS X.
This can be accessed by going to the Finder and selecting Applications from the Go
menu, then open the Utilities folder.
Select USB under Hardware in the pane to the left and then select the appropriate device
from the USB Device Tree. In the screen shot below (from OS 10.3), the device has a
deviceID given by:
Vendor Name: FTDI
Prioduct ID: 24577 ($6001)
A Vendor Name of FTDI is equivalent to a Vendor ID of 1027 ($0403).
