I've checked it, and it's right. Scanner works perfectly with other laptops with USB 2.0 ports. I have only 3.0 and eSATA in mine, and don't use any hubs.
Good to know that we're on the right track here.

What's interesting it uses xhci_hcd and it still claims it's just a full-speed USB.
Yeah, the attached peripheral determines that, and a companion controller (EHCI or UHCI) then handles the connectivity. However, it is clear that this is not being handled correctly. If xhci_hcd is loaded as a module (rather than being compiled into the kernel), then it would be possible to blacklist it, so that the controller only functions as an EHCI (USB 2.0 interface with ehci_hcd). I am intrigued that it only detects 'full speed' capability, normally associated with USB 1.0 devices. However, I'm at the limits of my knowledge with this.

Rmmoding xhci_hcd leaves me with no functional USB ports, and booting with it blacklisted doesn't make ehci_hcd take care of them. Is that unusual?

As a workaround, you may find that you can disable the USB 3.0 functionality via your BIOS. This would cause the USB ports to function as USB 2.0 controllers. (Make sure you only use USB 2.0 cables, and that they're not too long.)
I don't have any option to turn USB 3.0 into 2.0 in my BIOS - only to turn it off completely.
Hovewer, I managed to plug the printer into eSATA port (which I've done before):

As you know I made an additional thread in the "General" forum to have other members help out with your predicament and I'd like to write a tutorial/article (unless already created) would you mind if I organise a solved review with strategies from your thread?
Yes, this is exactly this Dell. I modified it by putting SSD instead of HDD (required awful lot of unscrewing, but damn worth it!), it has i5 processor and Nvidia (Optimus) card - but it's the same model as in http://www.cnet.com/laptops/dell-ins...-35127205.html .
I can see no point in switching the motherboard, I'll just have to live without my scanner...
As to organizing this thread, I'd love to help, just tell me what's needed. I could copy the info to Debian, Arch and Ubuntu wikis, too.
Additional idea: maybe eSATA port doesn't work (even though it's handled by ehci) because it's eSATA? Can I just force USB3.0 to work as 2.0 inside Linux?

I'm out of ideas for the scanner sorry-
What would be needed is all of the websites/links to the correct drivers for Brother printers to aid other members. Websites for Sane and XSane (that explained detailed info) and How To install. Also, a list of commands in order in which you tried that worked. Also; those arguments that were copied and pasted into the library (for functionality/performace/recognition) for the lib to have what it needs to aid the printer. Than; putting it all together knowing that it will work for other members is the key. In this case we would have to indubitably cross all of our t's and dot all of the i's. We must also think like a newbie because this could be frustrating to one without Linux experience. This would have to be approved by "Jeremy" 'Our Founder and Owner'
I've never written an article but I think this is our chance to do it...You agree?
As to the can you just force the USB 3.0....
I think because of the law of (interchangeability of 1.0/2.0) it wouldn't function-
May even cause a freeze to the system but I'm not a hardware Engineer and I (think) it wouldn't work.
I have a usb that causes a freeze everytime I use the darn thing; it's useless!
To be certain I'd have to do more re-search with eSata and the ehci details/facts.
