Hello,

Have to ask technical experts a question. We use your prestigious company's FT232 for communication between master and slave computers through USB to RS232 serial port. We used the driver of FTDI, but we customized it our own driver by wrapping it outside of FTDI. Our drivers mainly include two inf files: FTDI Bus and FTDI Port. The matter is that the device manager is unable to recognize the COM port. Our Port cannot be displayed under the ports (COM and LPT) of device manager.
Currently, it can only be displayed on 2 sets of ASUS laptops ( Windows 11 Home Chinese version , Intel Core i3, X64) under the device manager ports (COM and LPT) . Tried other brands like Lenovo, Hua wei, Dell, Hassee, Haier, even if other same model of ASUS laptops but all failed, it won't work. Including desktop computers. This problem has been troubling us and we stuck here for a long time and needs to be solved urgently. Otherwise, the Labview program that is nearly finished will be unable to deploy to the client's machine due to this driver issue!

Please help, the sooner, the better!

Thank you very much!
