Ok this is probably a simple question but how come I can charge my cell phone from a usb charger but when I use a voltage regulater at 5v out with a usb connector as the output plug it won't charge?
Does the pc send like a command to the phone? Or must I supply power to the d+ and gnd to the d- pins also?
The are 4 pins on a usb connector v+, v- and the other 2 data lines. How would I make this work? Sorry if this is confusing![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
