USB Tracking Software (free would be nice) and finding the missing one

So just a small backstory, I lost my other USB which is the SanDisk Cruzer Blade 8 GB, I don't know where I placed it. My theories are it was accidentally swept when our house is being cleaned or someone stole it because last Monday or Tuesday, an ISP guy went here to fix our internet. I couldn't remember where the USB was placed, it was either near the phone that was being fixed or up stairs. There was no important data on it, the contents was just the Memtest 86+ and some music and videos. So now, my new USB will arrive 6 hours from now. Is there any tracking software that is free that I can install so just in case that someone stole it, I can find it.

For the missing USB, is there any chance that I can find it (I presumed that it's stolen as I searched our entire house)? I don't want to call for a complaint for the ISP as I could be wrong. Here's the info about my lost/stolen USB.
