Hey all,
My other half and I picked up a TF300 to use as our "away with work" machine. She's had it for the last 4 months, and as we high-5'd at the airport she gave it to me with a couple of snags. I'm away with it now, so would prefer not to RTM it if we can solve this here!
The screen portion is working just fine, the issue is with the keyboard. It won't take a charge at all. Software reports the battery at 0% for the keyboard, plus the flashing orange LED on the power port side. It will allow the screen to charge from the mains while the keyboard is connected, so the issue is probably not the lead/connector/port there. The screen recognises that the keyboard is connected.
Also the usb port on the dock is refusing to recognise HDDs, memory sticks etc. It will give power over USB but seemingly no data.
I've tried a factory reset and have also upgraded to the latest uk firmware, to no avail!
Thoughts?

Hello suddenly my nexus s stopped connecting with data with the pc it only charges, tried with 3 diffrent computers with diffrent os , no menu popping on nexus and nothing connected on the computer(like i didnt connect anything), i removed the battery left it for some time installed stock rom still nothing.It was acting normally for a second and the other it stopped any help appreciated!
Are you sure you're using the cable that came with the phone? I have an LG Wink featurephone here that uses the same connector at the phone end -- its cable will charge my Nexus S (using the computer, obviously, but also when used with either the LG or Samsung charger) but no USB connection happens when I use it. Only the cable that came with my Nexus S provides a USB connection when I connect to the computer. I guess there are pinout differences between the two cables.
If you're sure you're using the right cable, I would guess that it's gone bad if it doesn't work on any computer. You can buy an (overpriced) replacement from Samsung or maybe a cheaper one on eBay or at a retail store. If the latter, be sure the seller lists it as compatible with the Nexus S.
it happened with the original cable ppfff i dont know...
same problem

Hi
I have the same problem
I have no idea what the problem could be.
We are not alone with this problem: code.google.com/p/android/issues/detail?id=13553
Now installed stock rom as well but still the same problem.
If i starting the NS in the bootloader mode the phone is not recognized by the computer.
It would be great, if someone knows a solution!

I've been trying to get help with this for weeks. No one is even responding to my posts. I thought it was something OBSURDLY simple, such that people didn't even want to waste their time responding to me.
Seeing same problem, No connetion via USB
Posted problem in General,, http://forum.xda-developers.com/showthread.php?t=1104245
Tried different cords, different computers and operating systems,, did cold start several times on phone (removed battery) still no luck, I am running totally stock
Curious do any of you have the Google Music Beta?? (maybe a over zealous rights thing?)
just tried it with a Win 7 machine that had never seen it before and it said it could not recognize the device,, me thinks that the MS device driver DB is messed up buy some recent Win update??
i sent it to samsung to change my usb slot because after connecting to pc and nothing happen when i went to charge the phone it took 5 hours to get to 30% so iam almost sure that mini usb slot malfunctions

My phone charges just fine. And my USB connectivity was fine until I manually installed 2.3.4.
~I had usb connection problems after upgrade to 2.3.4 a bit different but I managed to get the USB back by formatting the SD card.

I was on 2.3.3 when this happened, i tried to flash 2.3.4 then and again it didnt work but the strange thing is that when i was moving the mini usb the first times up and down it was shown for a moment as a broken usb device.Then this stopped and was not shown at all on the computer and finally the phone charged super slow when connected to electricity
Beginning to believe that it is a physical prob with USB connector on phone. It seems to start/stop charging when wiggling usb on phone but no mounting. Doe anyone know best way to resolve , T-mobile but bought from Best Buy? so to Best Buy? FOR SUPPORT /EXCHANGE? suggestions?
I've seen loose connections before. My suggestion ain't the cheapest but the plug, on the cable end, shouldn't wiggle. I went to a corporate sprint store, the ones that actually have working display phones, and got their usb to micro usb data cable. The thing with that cable is when you plug it in the phone side, it goes into the jack firmly. You can almost feel the little locking tabs click into place. There should be no play or wiggle with that cable as long as there's no damage or abuse with the jack on the phone. IMO, that's a good data cable. It's never given me problems before.
Also, sometimes the cable is only wired for charging. A true data cable will be wired correctly and be able to both charge and transfer data. Usually the cables that come with the phone are crap quality. I don't know if my suggestion will help but it won't hurt to have a good cable for data transfer and flashing. The last thing you want is a flaky connection from a cheap cable when you're flashing roms. Russian roulette with bricking a phone in a worse case situation.
Did you try reboot the computer and the phone? How about a different usb port? How about unplug any other usb device in case it's conflicting for some unknown reason? It sounds like so many people with windows 7 are having problems. Usually always happens with a new os that's released. Xp, for flashing devices and programming different hardware devices, has never given of a problem. I have a small partition with xp on it just for that purpose only.
off to Samsung for repair for me...
After time on phone with them and a factory reset belief is that the usb connector is defective. BTW Best Buy just hands off to Samsung 1-800 #
So Back to a barely functional G-1 for a while, glad I could find it!
So is Samsung or the carriers replacing or fixing units?
My USB data died shortly after 2.3.4 ota update.
Wifi FTP is fine for data transfer but I want USB debug to work...
Shame on google and Samsung, this bug has been around for months.
no shame on anyone...
I went through a factory reset with Samsung on phone that isolated the problem to what is apparently a loose usb connector, nothing to do with software... only hassle is sending it in for repair, as` mentioned problem needs to be dealt with Samsung customer service (not carrier or Best Buy), they were fine on phone...
I upgraded to 4.0.4 a couple of weeks ago and everything has been running smoothly until last night. It firstly wont recognise when the charger is plugged in or connected to a usb transfer cable (I've tried cleaning the usb, different cables and chargers, also a factory reset and cache). And also when I power off the phone it just freezes at the screen.
Can anybody help me?
EDIT: Problem solved thanks to strevellick. The solution was to gently lift up the micro usb tab so it made a better connection with the cable.
I have the exact same problem. Just started last night as well. Weird. Battery is almost dead and not way to charge it. I am looking forward to hearing some thoughts as well.
Make a full backup then install the 4.0.4 factory images from Google, through fastboot. Make sure you download the appropriate image. Your HW version can be found beneath the battery on a sticker.
If the problem persists, it'm most likely a HW problem.
If your computer won't recognize your phone, please connect to a Linux PC in bootloader/fastboot mode, and post the output of the following command (as root):
Code:
tail /var/log/messages
Well, I managed to figure out my USB charging problem. It turns out I fixed it with a small kitchen knife. On the phone in the USB port there is a small tab that creates the connection. Using a knife I gently pried up the tab slightly to make a better contact with the USB cable. Connected the cable again and it worked. Try that.
Oh my god, I was so skeptical about this because my tab seemed okay inside of the slot. But I moved it slightly and ALL of the problems have been solved! Including the freezing upon shutting down when connected to the power source. Thank you so much!
You are very welcome.
Hi
I have been having this issue for sometime now. I connect my Nexus to my laptop using the USB cable, and most of the time the screen starts acting up. Touch calibration is all wrong. When i click something, the actual button that is clicked is totally a different one. And sometimes it activates stuff on its own.
I have tried several stuff I found on google. Some said it had something to do with my home electricity not being grounded. I checked. It is grounded. Tried everything from flashing new roms to freshly starting from stock! Nothing seems to work!
Its like this thing have a mind of its own
Hi, if you use stock wall adapter, it's working correctly? Usually that is some kind bad electricity problem or that device where you plugged it causes problems.
Check usb cable. If it's not happening on LG cable and LG wall charger than it's your usb to pc cable problem
PS check other usb port and cable
Hello,
I recently flashed TWRP and CyanogenMod 13 on my Mi4. It was working quite well, I had some problems with the rotation sensor and some bugs in the software, but Quick Charge and also the Connection to the PC worked without problems.
Today when I was on my way home I was charging my Mi4 with a Qalcomm 2.0 Quick Charge Powerbank from Aukey (i have used it in the past on other phones, always worked great), but it seems that the USB cable was broken, it was charging very slowly and it also seemed to have a defective contact (the cable charged if i moved it around a bit, but in certain positions it wouldn't charge).
However, when i got home and plugged it in, I noticed that the phone also charged very slowly with the charger, so I thought that I would just flash MIUI back on the device to fix it, maybe it was a problem with Cyanogenmod. But that didn't work at all, the phone couldn't connect to the pc.
So, here's my problem: The PC can't detect the phone and it also seems, that the phone doesn't recognize, that its connected to a pc. Charging via the USB ist still working, but very slow. Also Quick Charging isn't working, it doesn't matter which charger or cable I use, it's always slow. When I connect the phone to the charger or the PC it takes like 5 seconds to recognize, that a cable is connected, then it starts (slow) charging.
The phone doesn't show up in the windows device manager at all (there are no unkown devices shown, the pc just doesn't react when you connect the phone). Also there is no message on the phone when you connect it (usually you can choose if you want the use your phone as a usb drive or just charge it). I also tried to activate MTP in the developer settings on the phone and turning USB Debugging On/Off, but it didn't help.
I managed to download a MIUI Rom from xiaomi.eu with the phone and installed it with TWRP, but it didn't help. So I think I actually broke the USB Port of my phone with a defective Micro USB Cable. The phone can still charge (very very slowly, no quick charge possible), but I can't connect it to the PC anymore. The pc also won't detect the phone when it's in fastboot mode.
I tried to look it up on the internet, but all I found were people with driver problems, and I don't think that I have a driver problem, because it seems like there is no connection between PC and Phone besides the charging.
Anyone knows something about this? Is it even possible to just break the data connection and the quick charging with a defective cable?
Hey, did you get your Mi working? I have a similar experience with mine.

No, I didn't find a solution for the problem. Phone is still not working, I even ordered a new charging port, but I made a mistake and ordered one for the LTE version. I have the 3g version, so the new charging port didn't even work with my phone. I don't want to spend any more money on it, so I just gave up on fixing it.
Same problem, and I am also stucked in recovery for now, never will buy phone without SdCard now...
Somobody found solution?
Hi
I have a slight problem.... My TF300 had some problems 2-3 years ago. First, it only just recognized the dock after the dock was connected to the charger. Then it stopped recognizing the dock at all. I thought the dock was broken. Now i got another working one and the same problem, the tablet doesn't recognize it.
It doesn't charge the tablet, keyboard and trackpad aren't working either.
The tablet can be charged (directly with the cable) and exchange data with my pc over cable.
Is that a known issue? And what is broken there?
Factory Reset hasn't helped
Greetings
