I wonder if this is another occurrence of a monster cable up sell?
Could be. As an audio guy I'm pretty aware of the whole cable
issue. Yes you can spend way more money for cables than seems
reasonable. Hundreds or even thousands of dollars. Per foot.
In a digital transfer environment I'm not sure it makes a difference.
In a digital optical transfer one can't really tell the difference between
fiber optics. I don't think you could attribute any signal degradation
to a wired digital (USB) connection. Either. Unless it was missing
some signal cable or something. In digital it's either there or it's not.
Charge more for the slight improvements.
In analog this may possibly be true. There's a definite argument
that cable composition makes a difference in the analog world.
At least audiophiles think so. I CAN tell the difference between a
stock Sennheiser cable and a Cardas cable. But I don't think this
applies to digital connections.

http://www.usb.org/about/faq/ I would trust such cables to be fully
compliant. What you say (the faq says) below is true, but how do you
know if you bought "fully compliant original USB cables" when you bought
cables way back when? Do you still have the product literature? . . .
Simple physics says that physical cable construction is important for
useful bandwidth. Try the old cable and see what happens. You may be
all right. Testing will take you some time.
The logo is on a piece of label "paper" (plastic, foil, etc.) that is
wrapped around the cable and sticks to itself such that it "wings out"
from the cable.
Cables that come with a product such as a hub should be compliant, but
generally don't have the label.
All this is just observed practice.
