Can anyone enlighten me as to what the exact difference is between these two USB cables? Are they wired differently internally or is it just a difference in the quality of the copper used?
I have tried several USB "charging only" cables to connect my GT-N7000 to a PC. Some will data synch and allow file transfers but only in one direction and only some of the time, some of them won't connect at all ie are charge only.
At least one cable I bought from a leading IT store stated "USB Data/Synch" on the packaging but only works as a data/synch cable on a Windows XP netbook but NOT on my Windows 7 x 64 desktop PC. It won't connect for data synch at all on the desktop.
I have Samsung's USB drivers installed on both machines.
Only the original Samsung Data/Sych cable works reliably for both charging and data synching on both my PCs.
Can anyone tell me what's going on?
Thanks in advance

All of those cables sound non-standard. A decent charging cable like the original Samsung one will likely have all 5 pins: power, data-, data+, ground and the other one which I can't remember. The power will be rated at at least an amp for charging and it should all work fine.
Power only cables may just have power and ground to keep costs down and some data cables are only rated at 500mA as that is to the USB spec.
I'd just get another Samsung cable, pretty cheap on play.com.

My problem is simple, i'm tethering my Wifi Nexus 10 to my Galaxy S3 and the S3 just doesn't have the staying power of the tablet and the AP is battery intensive.
I have considered:
Extended battery (unofficial) - don't want the bulk.
Extended battery (official) - not cost effective.
The other option would be usb otg and charger cable but I'd like a single cable if possible.
To make it clear - I'm looking for a double ended micro usb (B) cable.
If anyone knows of a reason this wouldn't work please do say
You could use this adapter with your original cable to see if it dies the job.

I have the same setup (nexus10 and s3) let us know if it does work.
You could try monoprice.com. I get all of my cords and such from them.
eBuyer tend to be pretty good for this stuff.
Just FYI, I tried this using an OTG adapter and a standard USB-A to USB-B micro cable. Depending on which side I plug the OTG adapter into, the S3 charges the Nexus (when the adapter is plugged into the S3) or vice versa (when the adapter is plugged into the N10).
EDIT: It would be interesting to try though what would happen if one was to connect the four pins (VCC, D+, D-, GND) directly to one another, with the ID pin being left unconnected (since that is what a Micro-B to Micro-B cable would most likely do). My guess is that nothing will happen, since neither of the devices assumes a master/slave state and so it doesn't know that it should supply power to the other device. I guess I need to order some Micro-B plugs at Digi-Key and whip up a cable...

On my desk, I have an old but reliable USB 2.0 hub, with your standard micro USB cable plugged into one of the ports. On my old phones (Nexus 5, Galaxy S3, HTC One), they would all charge from this cable, even when the hub was not plugged into a host. However, the Z3C seems to not charge at all when plugged into this cable, unless the USB hub is plugged into my Macbook. Anybody else seen this? I know that the hub won't put out much current, but it was awfully convenient to always have a charging cable on my desk regardless of what my laptop was doing.
Thanks!
Old post so probably not needed anymore, but just tested it over here and it just works.
A standaard generiek usb2.0 hub with external powersuply, connected with a usb 2 micousb kabel to the microusb poort of the sony z3c starts charging. It makes nog difference if i put the doc in between for magnetic charging, that works to.
Hi all,
I was wondering if anyone knew of a USB Y cable (with two male usb plugs converging into one female usb port) that could allow quick charge and data transfer so it could be used with Android auto? Both male usb plugs would need to be able to transfer data into the female usb port in order for this to work.

I guess this wouldn't work and might also damage the head unit, but I'm no engineer.
If I were adventurous enough to risk frying my head unit and/or phone, I would follow this
http://www.instructables.com/id/Add...-hub/step3/Cut-the-VCC-wire-of-the-USB-cable/
and connect the output of the quick charge car adapter instead of the external charger.
Then would cut the Vcc wire directed to the head unit.
I don't know if the main hub cable (the one which normally goes to the PC) has to go to the phone or the head unit: who's the host in Android Auto? I'm inclined to think it's the head unit, since the phone connects in mtp mode. So my first guess is main hub cable to head unit, quick charge adapter connected like in the article, then big usb to micro usb cable to phone.
Maybe voltage higher than 5V would fry the hub, and maybe Android Auto connection is so picky (and it's picky, you know) that the hub circuitry wouldn't allow it. Who knows.
Again I'm no engineer and I'm scared to try
But I would buy a safe device tested for this use case, 10/10 :laugh:

Use a usb y, but don't short the data pins to send it to high charge/current mode. You won't necessarily hurt the hu but you'll never connect to AA, the phone must detect the shorted pins to enter high charge mode. Which means the phone can't talk on the data wires. I find a 2a charger running at 1a plus the hu's usb keeps just ahead of the power usage.

Unfortunately, you can't have quick charge (2.0) and data transfer at the same time (at least with my Galaxy note 4). On a standard USB cable, you have 4 wires, two for data, two for power. On my GN4, the data pair communicate with the quick charger (I'm not sure exactly what the communication is, I remember reading somewhere it used the data pairs to communicate voltage, etc...).
Now, what I did do, was make my own data cable using 2 male type A adapters and connecting it all up to a a male microUSB end(Data pair is only connected to 1 of the type A male ends, I can't remember if I wired up the power in parallel). My AA head unit puts out less amps than my car charger, so even though I'm not getting quick charge speeds, I'm getting a bit more amps to charge with. So, one male end goes to my charger, one end goes to my head unit. I've been using it like this for over a year with no issues.
How much better is it than charging while connected to the AA head unit? Not sure. I'd rather have more amps than not enough.
Just buy a y. Cheaper and safer than self making.

Do you have a link? Can't seem to find anything that I think would work.

Hi,
I want to clarify some aspects:
1) Qualcomm's Quick Charge doesn't work when the USB is in use for data.
2) Quick Charge requires a certified adapter (as it's an active function).
3) USB power can charge the device, however very slow... in fact with AA the device consumes battery when running.
So, my question is:
- Increasing the USB power current with an Y cable the device can be charged more quickly?
- And if this is true: the Y cable needs to block the current from the dta USB port of the car?
I like to comment these topics.
I have tested with several cables and multiple manufacturers and multiple computers and cannot get a USB3.0/3.1 cable to keep a connection with the PC. USB 2.0 works fine.
I called Samsung and they are telling me that they only support the cable that came with the phone, which is a 2.0 cable. So they don't even support the 3.1 standard they advertise. I am about to return the phone over this. I have not found anyone else having this problem, but I have also not heard that anyone is using USB3 successfully either.
Yes I have success
I transferred over 7gb of data from a pc to a Note8 (sandisk 400gb Sd card) using a choetech USB c 3.1 gen 2 superspeed cable. The pc has superspeed ports (Alienware Area 51). Did not have any issue the two times ive connected the note 8 to a pc.
I have a type C to 3.1 type A cable from Anker, but have only used it on 3.0 ports on my laptop and desktop, definitely works super fast (even flashing the firmware with Odin - only takes a few seconds for the full package). I ordered 2 different cables though, one was apparently charging-only and didn't even work to fast charge.

I was planning to buy Anker Powerline Plus USB - C to USB A 3.0 cable. Isn't the cable good enough to fast charge the phone? Doesn't it charge as fast as the regular one (which came in the box) does? How much max current can be drawn using anker cable to charge note 8 and how much time does it takes to fully charge the device with anker cable compared to the original one?
Kindly provide these details, as I am confused whether to buy this cable or not.
TIA..
I have Trilink braided USB-C 3.1 cables that I bought on Amazon. They work perfect, super fast transfer speeds, and my phone charges the same as with the OEM cable that it comes with.

Does your PC actually support USB 3.0+ and are the ports setup correctly? Too many motherboard manufacturers poorly implemented USB 3.0 on their rushed motherboard, and Microsoft had to suffer the long end by providing poorly patched drivers because the boards never had the proper port insulations.

I will look into this but one is a brand new Dell Latitude and the USB 3 worked on my desktop with my S5.

Whenever I connect my Phone to my Laptop(Matebook X Pro), it quick charges my phone. (connection via usb c to usb c)
Is there a way I can stop that from happening and my phone leeching the battery from laptop so fast? OR stop charging it all together
Because usually I only connect my phone to laptop for roms and rooting and today for Android Q. I would charge my phone before doing these things hence I don't need my phone to suck out from laptop during this. I wonder if there is a way to reduce how much power the laptop is outputting. or turn it off all together
Besides, I have a powerbank for both my laptop and phone so if I am out and about, I'd charge the phone from the battery, it's less efficient to send it from battery to laptop to phone.
You'll probably need a custom kernel with special settings for that, as they usually try to speedup the charging instead, but I recall some bugged kernel/ROM versions (for another device that was; the Nexus 6P) which prevented fast-charging when not using an official QC adapter (like connecting it to the charge USB-port of your laptop; and that kinda sounds like what you're after). Many modern laptops have special charger-ports, sometimes even with QC support, so did you try another USB-port to see if perhaps charges slower ?

You see, when I'm out and about I only carry usb c to USB c cable so I can't check other ports. Both of the USB C ports are USB PD :/

Use a cheap legacy micro usb cable plus type c adapter. Since its hard to find bad quality usb c cable. It wont pass high current to your phone. Bad quality cable usually have very thin wire..
