How does USB stack enumerate a device?

Dear all USB Users,  (unsure that this is the right forum for my question...)

> Is there a way to programmatically "Recover Unused and FIX COM Numbers" (NI - National Instrument Forum Question...)

It is hard to live with the Totally Random USB COM port Enumeration that Windows always apply...

Is there a way to make this less Random, or even totally controlled and Previsible?

I found that for each USB device the following apply (or at least should apply)

Each device has:

- VID = Vendor ID

- PID = Product ID

- PSN = Product Serial Number

So with we have the possibility to make a COM-Port-Number Reservation/Binding Option for this USB device with Unique ID: VID&PID&PSN

This would result in the possibility for having the desired Unique Fixed COMxx Port Number Reservation...

.....................

The Windows USB COM-Port Enumeration is a worldwide problem... as it seems to be only totally dynamic...

Is there really NO way to fix or reserve COM-Ports some way...?

I found this software on the web: usbdeview-x64.zip and I installed it...

The Solution to this Problem could be just like DHCP MAC-Address to IP-Address binding...

If Windows USB COM-Port Enumeration could work this way:

Windows USB COM-Ports seems to use 2 or 3 parameters…
- VID = Vendor ID

- PID = Product ID

- PSN = Product Serial Number*** (seems to currently NOT being applied in Windows?)

=>

VID&PID&SN results in a Unique_Id_Number that could be bound (in the Device Manager)

to the same COMxx each time the USB Hardware is detected!

Thanks...

The World and I would appreciate a COMMENT to this...

And much better also an action to this problem...!

Thank you for reading ana all the best regards
