Hi all,
I have a FTDI 245 USB chip that's connected to a Cyclone NIOS. If I run the FTDI driver on one PC and the USB Blaster (e.g. Quartus programmer, NIOS IDE debugger, etc.) on another machine everything works fine. If I plug both the USB Blaster and my device into the same PC I get an error from Windows (XP) that it cannot load the driver while the same driver is already loaded into memory. Anyone know how I can get around this? Thanks, Andrew QueisserLink Copied

queisser,
I solved this by changing the name of the ftd2xx.sys driver to say ftdi2xx.sys. You will have to edit the ftd2xx.inf file and change all references to ftd2xx.sys to whatever you renamed it too then update the driver. As to why you can't have 2 different device ID's using the same driver file is not something I looked into. ciao- Mark as New

Works great, thanks for that tip. And the FTDI driver correctly enumerates both my device and the USB blaster!
