How found COM port number using USB COM adapter details

[mikkokh]

Hi.

 

I have several different devices connected to my desktop PC with USB COM adapters.

 

Sometimes there is some error that will cut my USB COM device communication (usualy caused by lose USB connector)... After reconnecting that USB COM adapter, by some reason, Windows will give it different COM port number.

I know there are some devices with integrated COM port circuit and they are used by client programs that can found them and only them by some USB hardware relate details and then use their COM port to communicate with correct COM device.

It would be better to define some known and static hardware related string from device managers USB COM adapter details to my script config file, than always redefine different COM port to it.

 

How can I do this trick with autoit?

 

I communicate COM devices with cfxUDF.au3 AutoIt UDF.
