I think it might be something to do with the thickness of the wires in the cable. Cheap cables have thin wires which have too much resistance for some phones.

Connecting my smart phone to the computer is easy, just connect the cable that came with my Galaxy fame and I can move files around, my old Nokia folder would only connect via bluetooth and persuading the phone and the computer to talk to each other could get entertaining, and when it was all sorted I could transfer to computer from phone but not to phone from computer.
From memory, but I think USB has 4 pins being power+, power-, data+ and data-, and if you connect the data+ and data- then (some, most, almost but not quite all) devices will assume they are connected to a dedicated charger rather than to a computer which can also do other stuff, and on that basis that they can charge faster by drawing more current than the 500mA limit allowed by the USB spec. Usually the said two pins are connected internally inside the charger, but it would also be possible - I do not know if it is common - to make up a lead that joins them.
