Make sure cable's bandwidth is at least USB2 capable i.e. 480MBps, which
meanbs proeperly shielded, twsited & balanced, and terminating plugs are
adequate.
And since USB3 is becoming a standard maybe get that if you can afford.
Also make sure connecting points are not made of disparate metals so
electrolytic corrosion wouldn't start in humid environment, and if metal is
agressive, then it should be plated with passive metal e.g. gold, platium,
iridium, etc.
You asked a question a,d I gave you an answer for an "overkill" cable.
But 99.9% of people are nonprofessionals and just go buy whatever is
cheapest. Most people have no concept of the above, and I agree if when
you'r ebuying a basic USB2 cable you start pondering these questions, you
must be insane OR you're an Electrical Engineer.
The latter is my case - I am an EE..
