If I connect my Pixel running NDE63V to my PC using the USB-A <> USB-C cable that was provided with the phone, I notice that with the cable inserted into the phone one way, Ampere keeps telling me that the power is being connected and disconnected every couple of seconds. Turn the USB-C connector the other way up and the problem doesn't happen.
Same problem with USB file transfer - with the connector one way up the USB connection keeps dropping back to charging only after it has been set to File Transfer, and I can't transfer files, with it the other way up I have no problem. Should this be happening? At the moment I don't have another USB-A <> USB-C cable to test with to see if the behaviour is the same.

so another charging problem. Tablet connects just fine to the pc with the cable but does not give any charge when connected to the wall socket charger. I thought maybe the adapter was a goner but went to my friends and tried with his cable on my adapter worked just fine. than tried my cable on his adapter and it wouldnt charge :S.. confused how can a usb cable stop transmitting all power but still connect to the pc :S? maybe the head is messed up.any ideas?
check there isnt any dirt on the connections on the cable. The connections are tiny and it will only take a spec to stop it connecting properly. Other than that its possible one of the voltage lines is broken in the cable but the data lines are still intact. Only a theory of course and if you have a DVM it will soon let you know.
Same thing happened to me. I called tech support they suggested to wipe the device. After trying other options I did a wipe but when it rebooted it didn't wipe but the tf did start charging after that... Perhaps that will help you?

Asus uses a USB connector on it's cable, but it is not wired to the true usb spec. When plugged into a pc, it acts like a usb 2.0 cable and provides 5v to the tf. It also uses two conductors for data transfer. The 5v will sloooowly charge the tf it is off. When plugged into the wall adapter, the tf provides a gnd signal on pin 7 of the usb connector, this tells the adapter to provide 15v on the normal 5v pin. USB 2.0 only uses 4 conductors /pins. USB 3.0 has additional conductors normally used for higher data rates. If you use any extension on the usb cable it must be a 3.0 cable or pin 7 will be unconnected and you will not get the gnd signal therefore wall charger will only deliver 5v and a very slow charge.
Hey bighunko thanks fir the idea but i nvflashed the new primeon it and it still wont work. I think maybe the power lines a goner. Never seen thishallen before to a usb. I tried everything. Even freezing the cable. It only works in connecting to the pc:s

When I got my Asus TF700T I got one power plug and 2 USB to tablet/dock plugs. The first thing I was VERY disappointed about is how short the USB cord was. When in my bed I could not plug it in I had to use it off battery only due to the shortness of the USB cable.
I went out and bought a USB male to USB female cord to use as an extension cord and low and behold it would not charge both the dock and the tablet when plugged into the Asus supplied AC adapter. I am assuming the extra length might have knocked down the power from the AC adapter just enough to not charge both devices.
What you need -
1) Original USB to Tablet Asus TF700T cord
2) Any length Male to female extension cable. I bought a 7 foot.
3) A 110-220 to 12 volt 2 amp power jack(car jack) converter. This is the one I bought any should work with the same specs. http://www.ebay.com/itm/130962356608?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
This is a very easy "hardware hack" to do.
1) Pull off the 12 volt car jack at the end of the converter it will leave you with a + and a - cable coming from the power brick.
2) Simply strip off the male side of the USB extension cable disregard the 2 data cables and just use the + and - power cables. Solder/clamp/or connect and cover each connection with electrical tape.
3) Plug the USB cable into the female end of the extension cable that is connected now to the converter.
3) Plug in your dock and tablet and watch both charge at a decent rate. This gave me enough cable length to plug it in behind my bed and be able to have it plugged in and on my lap.
Also doing it this way allows you to not have to hack up your devices USB cable and you can still take it out of the female end for any syncing or traveling purposes.
Hopefully this helps someone else who has issues with how short the charge cable is for this tablet.
A USB extension cable does work, but you specifically need a USB 3.0 cable. 2.0 doesn't allow enough voltage to travel through.
All I did was buy a lamp extension cord for .99, plug the wall wart into it and plug it in the wall. Now it's close enough to the bed or anywhere else I might be.

Or you could do that. :laugh:
Still the best solution, I quite agree.

...because the charger uses some of the USB 3 wires to detect the tablet and enable 15 V - with a USB 2 cable it detects only a generic USB device and charges it with the standard 5 V.

Awhile ago, I'd connected a USB extension cable to the charger that came in the box, and then to the cable that came into the box. In otherwords: Power>charger>USB Extension>Charging Cable. I've always gotten this message about my phone being able to charge faster if connected to a different charger because of it. I'm assuming it's because of the USB 2.0 Extension cable, which was a cheap one I'd gotten off monoprice. It still charges, slowly but surely. I do not use Fast Charging, because I have a ZeroLemon battery which does not support it.
Would I be able to just get a different USB extension cable to fix my charging issue and if so, can someone explain what type of extension cable to look for? Or, are there longer charging cables that support fast charging (should I swap out my battery for the stock one)?
I think the problem maybe due to the fact that you are using a USB extension cable to charge your device. I would try getting a longer USB cable to charge your device instead. From what I understand it doesn't matter what brand of USB cable you use to charge your device as long as it's manufactured properly.

I have an old extension cable (5+ years old) and everything works fine. I don't use it unless I'm traveling though.
Point is, it isn't because you are using an extension cable, but because of the extension cable being used.
Look for an extension cable that is thick. Don't buy anything with a very thin cable. They're usually made very cheaply. Also make sure that it isn't only a data cable, but either a charging cable or data + charging. I'm not really sure if this matters, but it may affect things.
Hint: an extension cable made for a Playstation 3 will work perfectly.

Get an Anker PowerLine USB cable. You can get it for like 7 bux for 10 ft.
I have a USB cable like this where the power strands were split into two to provide more power. This cable was originally from an external USB DVD burner, where the one female end plugs into the burner, and the two male ends plug into the PC.
I was wondering if I could use this same cable to be able to use a Quick Charge 2.0 wall wart while still be able to transfer files from the pc. Basically the female end will plug into the phone, the male data+power end will plug into the pc, and the male power only will plug into the wall wart. My end goal is to only have one cable on my desk to plug into my phone, and not have to go under my desk to switch back and forth between plugging the other end into the PC or plugging it into the wall wart for charging.
I was wondering if someone tried this before and if it does indeed work. Or if it will cause problems, like if the power current from the wall wart would flow into the PC and short something. Any ideas?
Thanks
USB-C Port Issues - "Charging Connected Device via USB" is a Constant Notification
Back info: So I charged my Pixel 3 once via the USB-C cable that came with it about a month ago, and I also tried the USB-C headphones too (around the same time) and both of these work just fine. I've since been using wireless charging and Bluetooth headphones.
I just got the pixel stand and noticed about 2 days after using that I keep getting a notification that says "Charging Connected Device via USB" even though I'm not using the USB-C port. At first it went away, but now it is staying through reboots and even shows up in safe mode sometimes. So I tried connecting the USB-C cable to the phone to see if it goes away, and I notice the cable doesn't charge the phone. Now if I power down the phone and plug the USB-C cable in one of two things will happen, but it depends on what side of the (reversible) USB-C cable is facing up:
1. The phone will start to charge and continue to charge if I hold down the power button and turn the phone on.
2. The phone will turn one when the cable is connected, but not charge the phone.
I don't think this is a hardware problem because I can use a USB-A to USB-C cable from my computer and it will charge/transfer files no matter what side of the USB-C cable is up. I also don't think this is cable or charger issues because I've used two different USB-C to USB-C cables and chargers (the set that came with the Pixel 3 and the set that came with the Pixel Stand).
I have also tried the USB-C headphones again and those are not really working either. I got them to work once by activating the Google Assistant as I was plugging them in, and they would continue to work after that until I plugged the charging cable back in. I tried the headphones again after the power cable, and they stopped working again. I now notice that the "Charging Connected Device via USB" will show up when I plug the USB-C headphones in one direction and not show up if I flip the USB-C port over.
There are some people with the issue over on Reddit, but no one seems to have a fix. One person said that a factory reset fixed his issue, but I've so many 2-factor authentication apps, that it is a real hassle to do a factory reset.
Well, the overall description of your problem does seem to point at a HW problem, since USB-C cables should be fully reversible on a hardware level.
Looks like it was corrosion.... I took a small brush to the port and cleaned it out. I cleaned it over clean surface and no debris fell out, so it is kind of concerning that corrosion would build up after halving the phone for just under a month.
