Hello community,
trying for half an hour to connect my note 3 to the pc using the OEM usb cable, I kept getting error 43 "Unknown Device" stuff but the phone was being charged. After that, I plugged it in my usb 3.0 external drive cable and got recognised instantly. What do you think is the problem here? I did happen to land the phone-edge of it in a yogurt bowl last week but, after cleaning it, it has been working normally this much time!
(Hope) someone else had a similar experience and worked it out...
Thanks,
jim
Original cable that came with my Note 3 has broken wire inside from new, I need to move it around few times just to get it connect inside and charge phone, Note 3 itself works fine with usb2 cables, or usb3 cable from my back up HDD, so I strongly suspect one of the wires inside your cable broke or has poor connection as well, but here it's data line, not power like in mine. Solution is very simple, use another usb3 cable, that should give you fast charge, or even usb 2, but here probably charge will be slower. You can find inexpensive cables online, also I don't think cables have full 1 yr warranty, like phones do but you may as well try warranty claim. BTW there is nothing special about Samsung charging cable as far as I know and at least in my case any USB3 cable will charge my phone at full speed, just like original cable as long as charger is original.

yes, Kies 3 has been installed since the beginning with the drivers. And as long as the phone is recognised through another cable, the drivers are definitly installed! Thanks again!

As long as I have the backup cable, I just leave the OEM in the wall charger and everything is fine. There is the fact that my Knox is 0x1, but I can just try the warranty with the cable and the receipt :angel:
Thanks again!

I just posted on the accessories forum about my experience with the Brodit active holder that I purchased. Mounted it in my car, and plugged the brodit charger in. Fuse in car charger went bang (not literally). Now I know it's not my power adapter in the car, as I've been using another JasJar charger and GPS charger for ages, so I went to Halfords and bought some replacement fuses. Tried them in the charger. Every one died too instantly.
I assumed the charger must be faulty, and arranged to send the holder back to Clove to replace it. It wasn't until I plugged my JasJar into the normal charger last night that I discovered it was no longer charging at all. I tried unplugging and replugging. I tried using the USB cable in my pc. Nothing works. Even the other car charger won't charge it any more.
I'm guessing I now have to send my JasJar to HTC for repairs and be without it for a couple of weeks. I'm not too happy about it though, and thought I would ask here first if this has happened to anyone else and if there might be a way to get it charging again without having to send it away.
i had a similar problem, i went to france with a charger that had a changable head, with pins for the different countries on click in plates, and on the top was a usb socket.
i took a standard usb to mini usb cable with me figuring this is a usb charger like the one that came with my phone but no, i couldnt get it charging, then after 12 hrs of it refusing, it eventually kicked back in, i sussed you had to use it like plugging it into a pc, ie, it turn it off, wait, then plug it in. bingo it started charging again.
its working like activesync, right pain, shoulda just taken me charger and a mains convrter
sorry it doesent really help but its poss related

similar problem. but i change the port miniusb. 30 dolares in mexico.
no problem, is easy. and now is working ok.
Well I've sent it in for repairs now. Couldn't get the thing to charge.
this forum is amazing...if there is an information available, you can bet it you can find it here...:
thanks carnivor: I had the same problem, but just was not smart enough to get the idea to shut it off and then on...with your help i solved the problem...i still don't get it, why it did charge with the original charger or with the usb cable from the pc and not with the generic usb charger and that same cable....and actually: it depended on the ROM installed: with the qtek rom it did not matter, with the t-mobile it did..
anyway: now it works. thanks!
I notice that the power lead is thinner than a usb lead so there may be less wires inside, ie 2 + ground instead of 4 + ground, the lack of TX and RX connections may well be what causes it. Im not going to hack into the charger cable just yet to find that out.
Intresting about the rom versions changing the fact if you can have device on before sync or not. Im not going to reflash now with an update around the corner im just going to wait for that.

yes, but interestingly it also doesn't work with the same cable that syncs and charges from the pc, when this cable is connected to the lighter or the generic USB charger...so the mess starts already in the charger.
but bottomline: as long as there's a workaround...
ook so this might be a bit hard to follow but here goes. ok i got a coffe mug thatkeeps coffee warm its a usb that plugs into either a usb port or a 12v adapter for ciggarette lighter. and i dont have a car charger for my hd2 so i plugged my usb into the 12v adapter witch has obviously a usb in the back you simply plug a usb into ok so i tried this to see if it would charge my phone and it didnt / no big deal soooo i plug my usb into my laptop to charge my phone ...not working not the battery wont hold a charge instead its not even showing the charge icon on the batt indicator like its not plugged in ....thought maybe i messed the usb end of the plug up plugging it into the 12 adapter for the coffee mug so i tried a second plug that had nothing to do with the experiment and its doing the same thing acting like its not even plugged in ...so did i fry somthing? batt is low but seems to be fine phone works fine other than the no charge issue and no anomalies occured when it plugged into the 12v adapter
update when charger plugged in says plug in charger confirming it doesnt know its plugged in

Sounds like you fell victim to the poor quality of the microUSB port on the HD2. If you can, I would re-flash back to WinMo6.5 and send it in for a warranty repair. If not, you're next best choice would be to send it into a 3rd party repair shop. =/ Sorry.
well this is the usb chord im talking about not the microusb

What? You plug the USB cord into the microUSB port and you're not getting any reactions. Sounds like the microUSB port is broken...
nonono ok have coffe mug with usb charger and 12v adapter you plug usb into i plugged usb from my usb data / charging cable into the usb 12v adapter to see if adapter would charge phone and now the phone says plug in charger when already plugged in like its not recognizing the charger is plugged in on both usb data cable i used to try the 12v adapter AND seperate charger that had nothing to do with adapter and the usb charger cable plugs into the phone
oooh ok where i plug the cable into is the microusb port i get it ... ok that seems to be fine to it was working perfect until i tried to use the usb 12v adapter to try charging the phone could the adapter have fried the charger hardware in the phone ?

Possible, the voltage is pretty high and could conceivable short your charging circuit...
All of the USB adapter should be outputting about the same since the USB ports are standardized for electrical output. I suspect your USB data cable could be at fault. If you phone doesn't react to your USB cable being plugged in, you also may want to try pressing one of the hard keys on your phone so that it can realize that you are plugged in via USB. I have that issue with my phone from time to time and just press one of the hard keys so that the phone knows it is plugged in for charging.
that somthin that can be fixed or is that a throw the phone away problem
believe me i tried ...... i pressed all kinds of buttons and no reaction.... and now the battery died so i cant do anything

I wouldn't throw your phone away... Try a 3rd party repair shop - they should be able to fix it for around $70... Expensive, I know, but it's better than spending $500 on a new phone.
they said if a different charger isnt working the phone is a goner

Definitely not true. They don't know what they're talking about and I wouldn't trust them anymore. Try CellularDr.com. I sent my phone in to repair for the exact same problem and it's in the process of getting fixed now. They even have the part to repair it. I've called and talked to them, they can fix it and they don't care about custom ROMs on the phone.
Hello.
I m having a problem with my transformer. Right now it is charging slow as if it was connected to the computer and not the wall plug. Also the message "Connect your Charger" won't go out of the screen, even if it is connected or fully charged. I flashed a custom ROM to see if it fixed something, but I had no luck. The cable works fine to connect the transformer o my PC the only thing wrong is that is is not charging properly and the message won't go off. Do you have any idea of what could be happening? My wall charger is model OB-1LF, which I believe is not the one with the known fault. Any ideas?
the adapter is surely broken.
This will sound nuts but, put your wall charger in a plastic baggie [push out all the air and then seal the bag] and put it in your freezer compartment for say 3hrs. Take it out [still in the bag] and let the charger warm up to room temp.
The charger may now work. It is worth a try. You would be trying to be sure the thermal fuse inside the charger is reset. I brought one back to life that way.

the TF uses pin 7 in the USB connector to signal the charger to use the 15v output. If the charger does not see a gnd on pin7 it will only charge at 5V as ypou are seeing. Are you using an extension usb cable? If no then check the pins on the TF and cable for bent or damaged pins. Also try the freezer as the charger may have gone into safety reset.
Thanks for the answers. I will try the bag and freezer to see if it gets fixed.
I know that this freezer trick works (also with broken hard drives too apparently), but what's the physical reasoning behind it? I swear I've seen a good explanation of it before but I can't remember..
Same problem here... Even had the charger replaced but of no use. It does charge wth a different (do it yourself) charger usig the same cable.Maybe that doesn't have the 5v/12v mode or something...
Going to order a new adapter and hope thatll fix it otherwise I'll send the entire transformer for repair i guess :/
I just got one today (got a good price on Amazon)
it just will not charge, tried all the fixes! not too happy as i went for the asus over the ipad and apparently quite a few people have charging issues with it.
charges very slowly through my laptop
From reading posts on forums is sounds like a few people are having it and Asus should of recalled the charger.
phone call to Asus tomorrow

There is overtemp protection circuit that should reset once the charger cools, but apparently it needs to cool down past room temp. The freezer is cold enough to reset it. I would not buy a new TF charger search for devcakes discussion there several aftermarket chargers that work well
Check the cable. I had the same problem. At first I thought it was because of faulty charger and had it returned and got a new one from Asus, but still had the same issue. Then I returned the cable for a new one, it worked flawlessly.
A plus: Asus gave me new cable which was much longer than the original one.
the cable is fine, used it to charge via my laptop
I had the same issue with my charger. I called up Asus and was able to send it in for repair, after a couple days they mailed me a new charger and cable.

Charging with your laptop does not involve pin 7 and supplies 5V. If pin 7 or that conductor is bad or you use an incorrect USB extension cable, the pin 7 signal will not get to the charger and will not supply the 15V charge voltage for normal charge.

Cheers will send the cable as well to be sure but am pretty confident its the power adapter.
Hopefully i will have an adapter for next week.
I had a brief play on it and i was quite impressed, the stock browser was surprinsignly good and may unistall dolphin.
I tried the freezer trick, but it didn't worked. I ordered another wall charger to see if it works. What's really weird about this is that the Connect your Charger message will not go off the screen. It doesn't matter if it has 100% charge it will still show "Connect your Charger".
In my case my Transformer didn't want to charge at all. The red light never came up while connected, the only way to fix it was to drain my Transformer all the way until shutdown and then plug it in and voila! It started charging again ever dince.
Great tips by the way!
Thanks

Just an update, after ordering a new adapter (with cable) it now works... Appearantly the cable was the problem afterall...
New cable with old charger = ok, new cable with new charger = ok, old cable with new charger = no go, old cable with old charger = no go.
And old cable with 3rd party adapter supplying 12V = ok, heh...
New cable is longer indeed, now I just need to think if I wanna go through the RMA process again for the old cable. But yeah, cable was the issue (out of nowhere btw).

The Pin 7 Connection I referenced earlier is bad. This prevents the charger from outputting 15V.

Yeah, I read your posts about that... couldn't see anything wrong with it on the outside though (with my eye) so unfortunately no clearly bent usb-pins or anything.
Any tips on things I can check? Could easily be on the inside as well of course in which case I can just forget about fixing it. At least it still works with another (non asus) adapter.
Mine was also doing a slow trickle charge. I ended up getting a new charger, but found that the problem was with the cable, not the "wall wart". I can still use my old one with the new cable and works fine as well.
Hi there,
The phone in question is a Galaxy S i9000 with the latest CM10 (same problem occurred with CM9 and another rom, not based on CM I believe).
First of all, it never shows any signs on the phone that it's charging. However, when connected to a PC, it does charge (it doesn't look like it at first glance, but the battery icon fills up). When connected to a wall charger, nothing happens. It does not charge. I also can't connect it to the PC in order to transfer files etc. Just charge it.
I cleaned the usb socket carefully, but that did not help. I actually think it isn't a hardware problem, because this problem has sort of been coming and going during the last few days, and as I've said it charges fine via the PC.
I've tried 3 different roms, but no luck. Also tried different cables and wall chargers obviously..
Your help will be much appreciated!

Apparently over time the USB slots tend to get damaged due to constant usage, had this problem with a china made charger ( shows charging but never charges) and still lately even USB cables seems to need some replugging or slide movements to get connection. For insight , try the cleaning method.
So, I apparently did something very stupid with my new Nexus 7.
I have a few 1 TB external hard drives, which don't get enough power via an OTG adapter from the Nexus 7 to run. So, I purchased a two into one cable -- that is, a cable that combines two male USB A plugs into one Micro USB B plug so that a USB 3.0 hard drive can use two USB 2.0 ports to have enough power. I had planned to use this to enable use of the hard drives with the Nexus 7 while traveling by plugging one cable in the tablet and the other into a charger.
When I got the cable I tested it by plugging one of the USB A plugs into my Nexus 7, and then I plugged the other into my computer's USB port. The Nexus 7 promptly shut down, the computer complained of a power surge on the USB port, and a distinct smell of melted plastic came from the computer's USB port. I guess the combining cable didn't combine so much as it just acted like a double headed male A USB cable and shorted things out?
The Nexus 7 refused to restart afterwards until I it plugged it into its charger. It works now, mostly. However, if its battery charge is above about eighty-seven percent then it always reports that it is charging, regardless if it is plugged in or not. And if I plug it into a computer while it is reporting that it is charging I have to restart the tablet to get it to connect to the computer -- I guess it thinks it is connected to a charger and doesn't bother checking for a data connection unless restarted.
The level where it stops thinking it's charging varies somewhat -- I've had it still claim to be charging all the way down to eighty-two percent charge, and by repeatedly opening the battery app over and over again I have been able to get it to notice that it's really not charging all the way up to ninety-one percent, but no higher, and I have to open and close the battery app an increasing number of times for every percent that it goes up over eighty-seven before it will notice it's not charging.
Any idea what kind of damage I'm looking at? How to fix it? Whether I can get the warranty people to fix it free of charge? If yes, whether they will send me a new one or just fix the one I have? Whether it's worth getting fixed since it mostly still works, and doesn't really bother me as long as it doesn't get worse?
Nothing?
Nothing from anyone?
Try replacing the internal USB plug? About $25. Easy to do your self.
