USB 3.0 cables are more complex and employ shielding for some of the added data lines (2 pairs) a shield is added around the pair sketched.

Im joining 5v to 5v, whats the problem, the power system is working in parallel (because the hub can take it from a pc or the battery) and the data. connecting the extra cable I just added to a male usb port that will go to my battery (usb power bank). The data cables for USB 1.x and USB 2.x use a twisted pair to reduce noise and crosstalk. Slit the cable open half way, find the red and black wires and make a T junction out of both. If USB host commands are unanswered by the USB device within the allowed time, the host considers the command lost. The USB 3.0 standard does not directly specify a maximum cable length, requiring only that all cables meet an electrical specification: for copper cabling with AWG 26 wires the maximum practical length is 3 meters.

The maximum length of a standard USB cable (for USB 2.0 or earlier) is 5 metres with devices operating at full speed (12 Mbit/s) or high speed (480mbit/s), and a maximum length of 3 metres with devices operating at low speed (1.5 Mbit/s) The primary reason for this limit is the maximum allowed round-trip delay of about 1,500 ns. Using the de-facto color is for industry types only. Just make sure the colors match from end to end. Typically, a USB hub comes with 4 to 7 additional USB ports so you’re able to easily connect all your USB devices when you’re removed from the organized workspace in.
