Kérdés minek ez a file akkor ?:)
talán itt a válasz:

Did you know each Arduino has a unique serial number in its USB interface that you can use to distinguish one Arduino from another?
If you deal with multiple Arduinos, knowing exactly which one is plugged into your computer can be a real time-saver.
But actually getting at this serial number and mapping it to COM ports can be challenging.
For Windows computers, here’s “listComPorts”, implemented both in GCC C code and in VBScript, both available from my usbSearch github repository.
csak az a kérdés, miért kell ezt minden tools menü megnyitásnál ellenőrizni.
olvasódélután on:
az egyik forumon igen keményen fogalmaztak ezzel kapcsolatban
először azt mondják, ez így jó, igy kell mennie, művészkedj te a kékfog és egyéb eszközeid beállításával/kitiltásával:

Quote from the official troubleshooting guide:
Why does do the Arduino software and the Tools menu take a long time to open (on Windows)?
If the Arduino software takes a long time to start up and appears to freeze when you try to open the Tools menu, there by a conflict with another device on your system. The Arduino software, on startup and when you open the Tools menu, tries to get a list of all the COM ports on your computer. It's possible that a COM port created by one of the devices on your computer slows down this process. Take a look in the Device Manager. Try disabling the devices that provide COM ports (e.g. Bluetooth devices).
és itt a válasz elég szigorúan:ez bizony tervezési hiba.
As sofware engineer I should add that it is a bug obviously. Devices should be enumerated in background, before any kind of menu is opened. To keep internal state correct, a system hook should be set. The problem is that software is written in Java, and such low-level programming in Java is very hard as it's positioned as cross-platform language and makes it hard to depend on system features. (This time it's a design problem.) – polkovnikov.ph Feb 27 '14 at 11:52
no, hát ennyit az olvasódélutánról.
