I plug my phone to my PC and instead of seeing "USB Debugging connected" nothing comes up. The battery icon says that it is charging, but the ADB doesn't pick up the device...
Any help is greatly appreciated. Ty.
Are you sure you have the usb debugging option enabled?
Yes!

hey friend..... Check the usb cable and the phone connector...... If both are working perfect then u can just factory reset ur phone....
The problem might be with the drivers on your computer try to see if SEUS or PC Companion can see your phone
I think my phone is a problem. because it is only charging. And he does not respond to the attached USB cable
settings are enabled USB port debuging. but the phone does not respond to anything, just to the charging battery. I think that here is a phone fault or phone drivers.
sorry for my bad english
I m pretty sure that ur phone's connector is not working properly becoz my usb is also giving me a little problem......

yeah I'm gonna guess your USB port is dead. Mine is gone on my phone and I'm stuck on miniCM9 with nAa-ics-02. My advice is SD reader for file transfer ADB over wifi for ADB and an external battery charger for charging. works for me

I have a samsung fascinate that will not connect to my computer no matter what I do. I have installed the drivers from samsung, I have connected through mass storage with usb debugging on, I have connected as mass storage without debugging on. I just cannot figure out why my computer will not recognize the phone. It just says that it is charging, and I am getting quite fed up with it. I want to connect it in order to root it, but if it will not read that the phone is attached, what am I to do? HELP ME!
Thanks!
Are you on Windows 7? Lately my pc has been doing the same thing. Except I can't get ANY usb devices to work. But here is my suggestion, shut down your pc, then unplug the power cord from the back and let it sit for a while. Then boot it up and see if that helps.

Also make sure you are using the stock cable. I've had problems with using an aftermarket cable before.
The issue was not using the stock cable... WHO KNEW?!
I had the same issues with the stock cable, on a whim I tried the cable to my kindle and it worked perfectly.

also just an idea, but check device manager to see if there is any errors with it, also admin privileges (not sure if needed)

eh sorry didnt see problem was solved
ok, so today i decided to help my friend fix her SGS2, since it was suddenly going CRAZY after she switched to her spare battery! she has been using it for only..3-4 months with no problems until today AFAIK. she is a normal user, so no rooting nothing.
phone version 2.3.3, zskg2.
so basically the problems that happened were that:
1.) MTP App thing kept flashing for a while, so i tried to turn it off and reboot. after a few times the MTP thing stopped, but then another happened. after powering off, the phone would still turn back on immediately by itself.
2.) Dock screen (as if the phone was docked) kept appearing for no reason
3.) battery life draining like crazy
so i thought it was just a software problem , i could flash a few roms whatever and it would be ok.
we thoguht maybe it was the spare battery's fault, so i eventually changed back to the original Samsung battery when trying to fix. no luck.
so i plugged the phone into usb on my computer. no response WTF? ticked usb debugging tried just usb media storage mode etc neither computer nor phone did anything when usb attached! BUT, the phone is able to charge from electric wall socket. very strange.
HOWEVER, when i ran ODIN, it actually detected somehow?! So i decided to uninstall and reinstall kies, thinking maybe it would help. i think after reinstalling, i plugged the phone in and it did install drivers, or maybe i was confusing it with some other driver installation.. actually i might be confused since i had my own SGS2 with me as well.
so after googling and searching a bit for things like 'usb problems' etc, i thought maybe her usb port was just dirty. currently dont have access to alcohol to clean it a bit but actually out of maybe 50 times of plugging and unplugging the USB cable i got the phone to have a response twice?
Anyway, I managed to flash CF-root and then flashed Litening ROM on her phone. it still does not do anything when i plug in the USB cable.
any ideas people? phone is just charging from socket now. after flashing litening ROM i still had one instance where it randomly changed to the Dock screen. weird as hell.
Maybe its broke and needs a warranty repair. Do you really think you should have tried flashing, making the warranty void?
On a more helpful note I spent hours trying to make my sgs2 connect to my new laptop. It would charge but not connect.
I got it to work by using a USB port on the other side of the PC. Simple as that. Something to do worth more power on USB port that attaches directly to the motherboard.

From what I read, it surely looks like there is something wrong with the USB/USB port/USB cable to PC.
I don't know an exact answer to solve your problem, but I can only list possibilities to certain fixes.
- Use a different port on your computer
- Try a different computer
- Change USB to PC cable
- Wipe Dalvik Cache
- Wipe Cache Partition
- Wipe Battery Stats
If that doesn't work, you have to go back to your local provider, assuming either Smartone, 1O1O, 3 or PCCW and hope that they would fix it for you IF you didn't reset your counter back to 0. If you want to bring it back and it is under warranty, get a USB jig off eBay, plug it in to the phone, and the custom counter would reset so you can claim your full warranty. (just hope that your USB slot can even recognize the jig when inserted or you're screwed)
uh oh.. crap. she didn't get the phone through the networks but yeah.. guess I might have to usb jig it etc. thanks for advice guys.

again, thanks for the advice about this .
this morning i did manage to get the phone to at least register that it was charging when plugged in to the USB, although it would still not do the USB debug or media storage mode at all. Additionally, the 'dock' screen also appeared several times after unplugging the USB. really strange. also tried using another computer and USB ports as well, didn't make a difference either..
i even tried turning off the phone, taking out battery and cleaning the usb port with rubbing alcohol, and it temporarily solved the self booting problem but it came back again shortly.
would you have any experience with whether the samsung repair centres void warranty or not in HK? i am getting a USB JIG just in case though..
just wondering: would I be able to use qtadb program to access the phones sdcard you think? since odin could detect and flash, but not kies or the normal windows driver stuff.
Sent from my GT-I9100 using XDA App
sounds to me like the usb cable is not working
or your pc case is not giving enought power to be detected properly, try to plug it directly to the motherboard usb ports
i also believe making the warrnty void was not the smartest choice lol
cheers

Easiest way is to place a Micro SD card into the phone, backup all data from the internal SD card to the Micro SD card. Keep it simple
Titanium Backup is a great app for that since you're rooted.

hi, thanks for the response! it shouldn't be the case since my own galaxys2 works perfectly fine when I plug it in. ah well I'm getting a USB jig today, it should be ok.. the phone responded to Odin , it's not completely dead#! (I hope)

You can connect QtADB with your phone via Wifi, so if USB does not work, since the USB does not really work.
Yes, QtADB works with External SD support
How to connect QtADB with Phone via Wifi
1) connect Your phone via usb, when it’s connected choose Connection->WiFi from menu and type phones IP and port (to change connection mode You need to connect QtADB with phone because its changing options in phone, not in QtADB. Next time You don’t have to connect usb before connecting via Wifi)
2) install on phone adbWireless and run. Press green button, it will show Your IP and port on phone screen. Type it to the QtADB and press connect.

It also breaks down storage info into system partition, data partition, internal and external SD cards etc.

My phone didnt charging with USB anymore... 3 times ago i turned off the phone em plug USB and try to charge, it started the phone normally but no charging... And now, trying any method and any USB works
My usb was bricked??? There is a way to know about it?? Ah log or a app that shows if a hardware are working??
Or any solution???
is your computer recognizing the phone when you connect it ?
if it is and charging is not working means that the charging pins of usb might be broken
I think the inner pins of a usb cable are for charging , they might be damaged .
Try using another usb cable

I used any other usb cable in other phones it works, but in my phone didnt USB cable neither recharger works i think it is my phone
crying!!
I'm pretty sure it's not the computer since I can detect other peoples S3 , and already tried it on several PC's ( kies and different drivers too)
is there a possibility of a busted USB port ? even though it still charges , but nothing appears in the device manager
Connect it to the PC in Download Mode to install some drivers automatically. So I understood it will work. For me it didn't work in like first week I bought it. Then, I was charging it on my PC for like half an hour and then it connected by itself. First days I connected it rzisted more nd more connected. Let's say like a car when you start it and push on the trothle. It goes more and more until you can go how long you want. Try via Download first then come back and report

Get a toothpick and clean your USB port on the phone. Had a problem that was similar to yours caused by dust .
That might be the problem.

.
Yes, because data uses other pins than charging does.
I have an other question, does your phone give -any- feadback at all when plugged in to a computer? Did you try a different usb cable?

Too bad, seems to me that you are right about the broken port.

connect the phone in download mode and observe if the odin detects it..
also try flashing any file through it(say recovery) and see if the transfer works.
if it does ..no issues with the usb , go for the pc then.
