Hello,
Thank you for your reply.
As mentioned, I wish to know the serial number for the connection I have already opened, since the tdi_usb_get_strings() function sometimes times out, meaning the ftdi_usb_open_desc() function also fails. Therefore, sometimes the user has to open by VID/PID only. In which case I would like to at least confirm to the user which serial number has actually been opened!
There must be a way!
Best regards,
Alex

xc3sprog in ioftdi.cpp also offers an option to open with VID/PID and
serial.
// Open device
res = ftdi_usb_open_desc(ftdi_handle, vendor, product,
description, serial);
Keep description NULL and you don't need to the the description.
Bye
