I've emailed FTDI about this, but in case anyone here can help me here's whats going on:
in 'Device Manager' I don't have a virtual comms port under 'Ports (Com & LPT)',
I just get a new heading called 'smart card readers' with 'acg pc/sc reader (usb)'
my install process went as follows:
I plugged in the device, it asked me to locate the driver for FT232R USB UART,
i selected the driver folder and it installed the 'acg pc/sc reader',
and then an error message appeared saying the machine would reset...
this appears to be at the stage where the install would prompt that it was going to install a usb serial port
if you have any advice to help with this it would be very much appreciated...
and if FTDI get back to me I'll post the reply here
