As you might know, the FTDI driver exists in two flavors, VCP and USB DLL. The one that is used for the Irtrans device is the USB DLL. I've bought a scmartcard reader device that plugs into a USB port but coincidently uses an FTDI chip internally also. This device requires the VCP flavor. Since Windows XP doesn't allow both drivers to be installed at the same time, I either have a working IRTrans or a working scmartcard device. The FTDI website (http://www.ftdichip.com/Support/Knowled ... index.html)recently released a driver that should be capable of both:
"FTDI have previously provided two types of driver for Windows: a D2XX direct driver and a virtual COM port (VCP) driver. Previously, these drivers were mutually exclusive and could not be installed at the same time. The new Windows combined driver model (CDM) allows applications to access FTDI devices through either the D2XX DLL or a COM port without having to change driver type. However, it should be noted that an application can only communicate through one of these interfaces at a time and cannot send commands to the D2XX DLL and the associated COM port at the same time."
I tried to manually update the IRTrans USB driver but it refuses to see this new driver as a valid candidate. Do you have any idea if this driver could be incorporated and solve my problem?
