[QUOTE="Andre Levite, post: 92926, member: 10850"] Although a handful of USB cables may appear similar externally and have the proper connectors they can differ in terms of circuitry and pin connection. Some are charge only while others include data lines. Some devices demand a signal from the data lines even when only charging. The Spark will only accept a charging source when it provides a charger signature at the D+/D- pins that it can understand. Some cheap cables don't include D wiring at all. Others short out the D+ to D- wires in hopes of imitating the charge signature but without success. I've got done Sony noise-cancelling headphones that only accept an even smaller subset of micro USB cables. Best to mark these cables with colored zip tie and store them with the corresponding device to minimize this issue. [/QUOTE]
