My USB/serial db9 works with my win7 system when I connect a serial programmer with it, but will not recognise my serial device on my win10 laptop. The USB/serial adapter is installed ok on the win10 system, it is there in device manager working ok but when I try to connect the serial device it is not seen. Same process works ok with win7 system.
Thank you for posting your question. I’m David, the same person who worked with your earlier issue involving the adapter.
Could you please tell me the make and model of your serial programmer, as well as the name of the software you are using to connect to it?
