Appendix I – ProScan III FTDI USB Field Issues and Solution.
Recently the ProScan 3 controller has had an upgrade/change to the USB connection
hardware. The company FTDI Ltd. manufactures the hardware and constantly updates the
associated Windows USB Driver. The new USB hardware and interface driver is Windows
Hardware Quality Labs (WHQL) tested and will automatically download the latest drivers
when connected to a PC with internet access. The Driver Software Installation Window
shown below will alert the user that the USB driver installation is complete and the Port is
ready to use.
When a PC is not connected to the internet and an older or no FTDI driver is installed onto
the PC there can be problems communicating via USB. The driver can appear to have installed
correctly and yet not communicate. The image below is from the Device Manager of a PC
where the ProScan III FTDI USB driver has set up COM3 on the PC, but USB communications
is still unavailable.
Alternatively on some installs the USB connection can show up under "Other devices" as
FT232R USB UART
Right clicking on the ProScan3 USB port in Device Manager will allow you to click on the
Properties menu.
