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!
