Hi,
I'd like to make USB - lightning cable that connects laptop with iPhone. I assume that when laptop is not connected to power supply then it is not grounded? Or is it grounded through chassis just by laying on the table?
Which is the best option to shield such cable:
A, shield connected to USB Ground wire through the whole length of the cable
B, shield connected to USB Ground on both ends of the cable
C, shield connected to USB Ground on single end of the cable (does it matter which end?)
Which shield is enough for this application - braided, foil or both? thanks a lot
