When buying electronic products that use a microUSB plug for powering, we often receive a
male USB <--> male micro USB charging cable that doesn't include the 2 DATA lines (Data + / Data -).
It's extremely annoying for the end-consumer, because :
at the end you have a big amount of USB-µUSB cables at home that you cannot distinguish visually (no distinctive symbol on the cable): some of them are "power only" (won't work to transfer files from phone to computer for example), some others "power+data" (will work for file transfer).
it can lead to ambiguous situations like "My device X doesn't work anymore. I plugged it to my computer and it's not recognized as an USB device". In fact it's just that the cable is not a real USB cable, but only a charging cable.
Question: Is there an electronic justification to produce micro-USB to USB cables that don't include the data lines, except for saving 0.00001$ per cable for the maker because they can avoid 4 soldering points for the soldering robot?
