Troubleshooting
1. How do I know what my device ID 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 device ID given by:
Vendor Name: FTDI
Product ID: 24577 ($6001)
A Vendor Name of FTDI is equivalent to a Vendor ID of 1027 ($0403).
If the device does not work after installing the driver, it is likely to be because the PID is
not supported by the driver. If this is the case, contact FTDI Support with the PID that
needs to be added to the driver. If the VID is not 0x0403, it is likely that the device is not
an FTDI device and we cannot support it.
