Another thing several of us do use here to troubleshoot this kind of problem, is to download a free copy of Ubuntu Linux and burn onto a blank DVD disc or Flash Drive and boot to it. I've had many computers that wouldn't work with
ANY mice, wired or wireless in Windows, and when running from Ubuntu in LiveCD mode (in Memory), the mouse suddenly jumps to life!!
This tells you that it's a Windows issue or a possible hardware failure such as a failing/faulty RAM Stick or failing/faulty Hard Drive. The Ubuntu bypasses both Windows and the Hard Drive, but not the RAM. So, if your mouse device begins working in Ubuntu; it's most likely a software issue as you surmise; unless of course your Hard Drive is being wonky.
We usually recommend that you
TEST your Hard Drive first, so if you cannot resolve your hardware using traditional methods of uninstalling/reinstalling drivers, and other driver related repairs such as kemical suggest, you may be looking at a complete Windows Reset or Windows Reinstallation from factory Recovery Media. If your
RAT 7 mouse works with Ubuntu, and you can't fix it with driver repair methods, you should test your hard drive, and then apply more aggressive Windows repair or reinstallation techniques. The fact that the mouse works on another Dell PC, means the mouse is good;
so there is something wrong with your XPS 15 PC.
Before you start any of these repairs, I would strongly urge you to
FIRST BACKUP ALL OF YOUR PERSONAL DATA TO EXTERNAL MEDIA! THIS WOULD INCLUDE YOUR LIBRARY FOLDERS FOR DOCUMENTS, PHOTOS, MUSIC, VIDEOS, AND ANY SAVED E-MAILS OR ATTACHMENTS IN ORDER TO AVOID IRRETRIEVABLE DATA LOSS!!
Regardless of the repairs you attempt, and your hesitance to have to rebuild your Windows from scratch, this is a
MUST-DO-STEP!!
Next, I'll provide you with the links you need for everything I suggested above here:

If you follow the links above in order, I believe you have a very high probability of solving your mouse issue on your XPS 15.
3 other things to consider:
1.) Did you try a wired mouse such as a Dell, Microsoft, or Logitech mouse on all USB ports on your XPS 15 PC? Did any of these mice work on any or all of the USB ports?
2.) If your
RAT 7 mouse fails to work on your XPS 15 with
Ubuntu LiveCD (running from Memory), chances are very good that you have a hardware incompatibility within the Motherboard of the XPS 15, and that mouse will never work with that PC!
If you reach this point, you should follow kemical's suggestion to contact
Mad Catz, the manufacturer of the Mouse device and ask them for help. They may be able to provide you with a special driver that may work your model Dell PC, or at the very least post a
"No-No" message on their support forum or knowledgebase that your Dell XPS 15 does
NOT work with the RAT 7 mouse you own.
That way, nobody else will have the problem you encountered. Ideally, it should be labeled as
INCOMPATIBLE on the product packaging, though in my experience manufacturers only print
COMPATIBLE computer models that are known to work with their device, not the other way around.
3.) If
#2 occurs to you, and the manufacturer can't help you or provide you a special custom driver for your PC, it might be time to change vendors, and buy a gaming/high performance mouse from another manufacturer, such as Razor!
Hope this provides you some further direction.
Best of luck,
