chargingmacbook prousb
I have a new MacbookPro with only USB-C ports. Does there exist a wall charger for USB-C that can provide the appropriate power while also providing a sort of built in dongle for USB and an SD card reader? I am looking for something like the below image, where the extra USB ports also provide data to my mac when plugged in via USB-C. Does such a product exist? I would never need to remember to bring another dongle again, just bring my wall charger.
I have tested an iPhone 5, and on my system it charges from a USB 3.0 port at the same rate as a 500 mA USB 2.0 port. As you would expect, the included 1 A wall charger is about twice as fast.
Unfortunately, your USB port has died
You've done more than enough tests to diagnose the problem and unfortunately this one is hardware related, not software or firmware. There's no NVRAM setting or SMC control that handles power to the USB (directly).
The "light" that you are seeing on your USB device doesn't mean it's connected and recognized by the computer. It simply means it is receiving power on the +5V pin of the USB port.
Looking at the pinouts of a USB 2.0 Port, we can see that there is a dedicated +5V for power (why your phone charges) and two pins for Data (Data+/- for positive/negative voltage signals) and a ground. Data isn't being transmitted (which is why your iTunes doesn't recognize your phone).
What could the problem be?
Any/all of these would contribute to the weird behavior you are seeing.
From iFixit.com, we can see that the board layout as follows:
The good news is that this can be fixed. It's not a DIY type of repair, but there are shops that specialize in component level repairs. Just do a search for "MacBook Logic board repair" (Rossman in NYC is really good - not affiliated, just a happy happy client)
Since you indicated it was only one USB port, the chances are good it's just a bad connection with the physical port itself. An immediate fix would be to purchase a USB Hub (powered preferably) so you can get your connectivity back.
Best Answer
Nothing in a very convenient form factor like that or that include an SD Card Reader. There are some good USB-C Docks that provide connectivity and charging Kensington SD4600P USB-C Docking Station or CalDigit USB-C Docking Station but they may not be quite what you're looking for.
