USB Port Died a death by iPhone

If you can't find it, the car should still be under warranty?

 

The USB socket is not intended to provide power at all. Only connection into head unit for music etcetera, so maybe she hasn't wrecked it after all. I can't give you chapter and verse, but read the manual and it will explain all. Sorry for being so vague with my help, but @Prodigyplace is usually brilliant with detailed follow up after my off-the-cuff advice.

 

Got me interested:



And yeah, I guess if you want to charge a phone with a USB charger cord, you should be plugging a usb adaptor into the regular 12 volt outlet (aka cigarette lighter socket).

 

The USB standard was not originally meant for the current needed to charge a phone.
Apple then introduced phone charging while maintaining backward compatibility with lower power USB devices.
The USB standard does not require enough power to charge a phone.
I have heard of some Samsung fast chargers using a USB connector but are not backward compatible with USB. They can fry a lower power device.

 

Thank you for clarifying gentlemen. Don't know what I'd do without your support/help.

 

@Prodigyplace you sound like you know the ins-and-outs of iphone charging. I on the the other hand, well I won't go there.

I did learn along the way: our iPhones require the smaller AC adapter, but my wife's iPad need a larger adapter, with more oomph. Trouble is there's nothing stopping you connecting them the other way 'round, possibly getting into trouble. I also resign myself to Apple store visits for such items: the ones they have for sale in the grocery stores are hit-and-miss junk.

Unquote.


With Apple's artificially high pricing, it's no wonder the cheap Chinese copies proliferate as wildly as they do. These clone failures only serve to keep customers returning to the Apple store with more $$$$$

 

Thank you Mr Leisk. I had no idea what that little "USB" plug is for. (I'll never use it! And what is an iPod??? LOL!)

I did use the cigarette lighter socket ONE time, to charge up my cell phone. I just use the "car cord" that came with my phone. It seemed to work fine.

I'll leave all that USB stuff for the younger generation.

 

Doh. Meant to say iPad.

 

Probably very wise decision, but for the iPod:-

iPod - Apple

 

You were correct the first time. It does say iPod in the owner's manual.

Thanks. I've never really even looked at an iPod. Don't need it for music, as the car came with 300 radio stations! And I listen to only 3. (It's like cable TV with 300-400 stations, and I only watch about 6 on a regular basis. A complete waste of money.)

 

Wow there are some uneducated responses here.

1. No trouble at all charging an iPhone 6S. Phone does not complain about the USB port at all. The USB port is perfectly capable of charging a phone. I believe the USB standard is 1 A of power. If your phone can take more then it just won't charge as fast as if you plugged it into its native charger.

2. The reason you have a bigger adapter for an iPad is that the iPad takes 2 A and the iPhone only needs 1 A. But plug the iPad into the smaller iPhone power plug and it will still charge, just slower.

 

They were THE Thing a few years ago, if not so much now. Mainly thanks to the improvements in smartphones.

Three stations!!! I'm usually faithful to two, ok, mainly one.

You will have to check your US manual to verify, but another subscriber to PC posted this on 5/28 last year.

"Most modern phones (and all tablets) want to charge with more than 500mA. Most will still accept the USB spec current, but I know my phones will complain about "slow charging" if that's all they see. I think Apple was the first to tie the two data lines together with a certain size resistor to indicate that a standalone charger was capable of delivering more than the standard 500mA limit on the remaining two power lines.

The charging device identifies the type of port through non-data signalling on the D+ and D− signals immediately after attach. A [dedicated charging port] simply has to place a resistance not exceeding 200 Ω across the D+ and D− signals.

Per the base specification, any device attached to [a standard data port] must initially be a low-power device, with high-power mode contingent on later USB configuration by the host. Charging ports, however, can immediately supply up to at least 1.5 A. More current may be supplied up to the maximum current of 5 A, but the charging port may apply current limiting, or even shut down. The maximum current is determined by the over-current protection maximum current in the baseline specification. Note that it is specified only that USB connectors are tested to a contact current rating of at least 1.5 A.

-- USB - USB Battery Charging (Wikipedia)

I think/hope the Prius port is at least USB 2.0, and that spec maxes out at [email protected], but since the port in a Prius is not a dedicated charging port then it must present itself as a 500mA port until it and the device negotiate (in software) a higher current rate. USB 3.x allows higher power levels, but I doubt our port is USB 3.

Proprietary technologies like Qualcomm's Quick Charge 3.0 and the standardized-but-not-yet-ubiquitous USB Type-C supply up to 3A. I don't know what Apple uses, but my Android device is a QC device and some of the newer Nexus phones are Type-C. The Prius connector is not physically Type-C, and it is unlikely to support Apple- or Qualcomm-proprietary tech.

In summary, I expect the Prius USB port to comply with a particular USB specification and you won't get any fast charging beyond what that spec provides. Hopefully it's USB 2.0 and not 1.x, but even with 2.0 you still need the device and the car to successfully negotiate currents higher than 500mA.

I don't know what you mean by this at all. A USB to lightning port cable to an iPhone works just fine in the Prius. It seems to charge reasonably fast so I suspect it can put out the 1A that the iPhone wants. If it were only 500 ma I would have noticed how slow it charged.

 

I hope @Confrad in VA will return to share the outcome of the dealer’s troubleshooting.

The USB port and audio input jack in the center console are part of what Toyota calls the No. 1 Stereo Jack Adapter Assembly (part number 86190-42040, list price $114.58), which is connected directly to the Entune head unit (the Radio and Display Receiver Assembly or Navigation Receiver Assembly) in the instrument panel by two shielded cables, one for USB and one for audio.

If the USB port isn’t working—unless there is a problem with the customer’s USB device, the Adapter Assembly, or one of the cables—the only alternative discussed in Toyota’s Repair Manual is to replace the entire head unit; there is no mention of a separate fuse for the USB port. It wouldn’t surprise me, though, if there were a fuse inside the head unit, which isn’t considered a field-serviceable part.

The Repair Manual also says the USB port is compatible with USB 2.0, at Full Speed (12 Mbps) and High Speed (480 Mbps), and that it works only with the first two devices found if a USB hub is connected, but there is no discussion of the maximum current available.

If you’re looking to add USB ports for power only, Southeast Toyota Distributors sells a Dual USB Power Port option kit, their part number 00016-00222, to add two USB ports inside the console box. It’s installed by tapping the wires for the front power socket.

The Repair Manual, Electrical Wiring Diagram, and instructions for the SET option kit are all available by subscription to techinfo.toyota.com.

 

iPods are so obsolete. I can't believe they still sell the iPod Nano and Shuffle. What a rip. Just buy the 512GB iPhone and put your music on that.

 

Is my "flip-phone" obsolete?
