    Teensy 4.0 Serial Driver for Windows 7

    I have a product that uses a Teensy 4.0 for PC communication. On Windows10 it appears just as "Serial USB Device (COMn)". On Windows 7 32 bits it appears as "Teensy Comport (COMn)". Is there another driver for Windows 7 to show as "Serial USB Device (COMn)", instead Teensy ? I tried NXP rt1062 serial drivers but did not work.

    The "driver" is merely a text-only INF file which tells Windows to use its own USBSER.SYS driver. You can create your own INF. There are many examples on other websites. Usually you would just copy one of those examples and edit the "Hardware-id" and the description strings.

    But to get Windows to actually use your INF, you must create a corresponding CAT file with the valid digital signature. Microsoft's SIGNTOOL.EXE requires a code signing certificate. This is not free. The lowest price I have found is ksoftware at approx $80.

    Here are prior threads where I have described the process in more detail.

    Even if you do this, there is no way to solve the Windows 7 USB driver bugs. If possible, you should avoid use of Windows 7 or 8. Only Windows 10 has good quality drivers. (well, also Linux and MacOS)
