Peter,
As long as you:
a) Use the same USB ports for each device
b) The port was not already used previously
You will always get the same port upon reboot. The problem probably lies with the b) above:
at some point this serial port was used and is "blocked" within Windows. Clicking on "show all
devices" will NOT show all old devices no longer used. That is what is probably confusing you.
To solve that, do the following: make a batch file containing the following two lines, or else
enter then into a DOS box in order:
set devmgr_show_nonpresent_devices=1
\windows\system32\devmgmt.msc
Then when the Device Manager comes up, click on "show all devices". These older no longer
used ports will magically show-up. Then you can delete them. I hope this solves your problem.
If things really are nasty, one can easily completely delete all USB devices from the Device
Manager and reset Windows. In this case, you need to make-up a batch file containing
the following lines:
devcon.exe remove =USB
devcon.exe rescan =USB
Be very careful if you use this, since all devices will be reallocated new ports from scratch.
