when i plug my phone into my computer, nothing. the phone pops up the notification to allow mass storage, but when i enable it the computer never shows the phone. i've messed back and forth with usb debugging, still nothing. is this sometihgn stupid i'm doing or what? I've even flashed a couple roms andstill nothing. help please?
its most likely the usb cable try a differnt one
that's what i thought, i tried two different cables (all i have are 2) and neither will work. Note, that when i use these two cables with the wall jack to charge they work.
do you have another computer? try it with another computer
or try a different usb port! or try installing mini kies that sometimes fixes the problems
Try rebooting and turning usb debugging off. Then plug up to pc (see if it installs drivers) then unplug, turn usb debugging back on and then plug up again. Should work after that.
OP-
A few days ago I posted regarding my similar issue (2-3 pages back).
I have still not resolved my problem, but that thread may give you an idea about troubleshooting.
Let me know if you figure it out.
For me, its most likely a phone issue & not a cpu problem.
I'm going to try cleaning my port with isopropyl alcohol later this afternoon.
You also might want to look at Callip's advice in the "PLEASE HELP" thread on this page.
wow, thanks for all the responses guys, i'll get to all this tomorrow some time and i will post my results.

So, I'm having an issue where my PC can't see my phone with PC Companion open or closed, Phone on, off, or in recovery, with 2 different cables, and with USB debugging on or off.
Does anyone have any suggestions? Or do I just have broken pins on my USB port? cause I can still charge via USB.
Also, I'm on the wrong kernel so I can't access ClockWorkMod and update the ROM
I'm using an old version of this ROM (last updated mid-October, 2011)
tl;dr: PC can't see phone when plugged in, tried common sense options, what do?
More info: I did some research and found others saying they got a message saying "Unrecognized hardware" I don't even get that, nothing happens at all when I plug it in, although the phone does charge.
I have also tried 2 different PC's (both W7) and all the USB ports on both.
I would guess that the pins are busted in your phone. There are a few people with this hardware issue from my reading of the forums so this is not uncommon.
I'm in the same spot, I haven't been able to USB connect my X10 for months. The repair guy told me it wasn't fixable, so I'm stuck with locked bootloader and xRecovery flashing only.
Sent from my X10 using XDA App
That's about what I found too. Someone said to try rubbing alcohol and a q-tip or blow in it (a-la NES style) but I doubt that will work. At least you can flash with xRecovery though, I screwed something up and can't access it anymore.

Try that.. hope it helps.
My problem is that I cannot connect my Galaxy S II to computer. When I try to connect it only says "unknown device". I have tried with newest Kies and without Kies. With multiple computers with Vista and Windows 7 32bit. Also downloaded Samsung Galaxy S drivers manually from web but with no avail. And I have tried with Usb-debugging on and without it. I also tested USB-mass storage setting but it does nothing. Computer also says "unknown device" when I try to connect phone while in download mode.
The charging works btw.
When I connect the cable my phone just makes the normal sound but the mass storage android man newer appears to top tray. I have also made factory reset and cache delete from recovery but with no luck.
I would like to flash different rom with Odin but I cannot do that when the connection is not working. My current rom is official XXLPQ ics. The usb cable isn't the problem because I have tried with different cables which work normally with other phones.
Is the warranty repair only solution? Really wouldn't want to be without my Galaxy during the repair time.
Sounds like it's going to need a check over, if it wasn't for the fact you have tried multiple computers AND leads, as I had a similar problem but found it was down to my PC needing a fresh install.
Unless others with similar experiences have advice it doesn't sound good, as though pins 2, 3, or 4 have problems maybe, or that the board within the phone has bent up or down through rough handling/tug on the cable.
When did it start happening? I had a fright by tripping over the phone while plugged in, and ripped the plug out while launching the phone across the room. It broke the charger and thought I'd killed the port on the phone, but found if I propped the plug up and put weight on the phone it would connect, like this...

Might work if the board has got a whack like mine did.

Did you even try to search? Plug your first sentence into the search all forums bar and see what comes up. There are so many threads on here about that problem. Give the search bar a try before creating a thread. That is on of the rules here.

Yes I did, I searched for a couple hours looking through threads even went to different websites. None of the solutions worked so I created a thread hoping someone could give me an answer as to what is going on with my phone
By your PC not charging your phone it is very hard to tell. Lets start with the basics. You have tried different usb ports on the computer. You have turned on USB debugging on your phone. You have tried different USB cables. You have uninstalled and re-installed kies on you computer. You have done what you could to clean the usb port on your phone. You have tried to connect your phone to the pc in download mode. That about exhausts my limited knowledge. Sounds like you have been pretty busy over the past couple of hours to get all that done. I am not sure what to tell you besides it sounds to me like your phones usb port is toast. Maybe you can do some searching and see if you can find some one that can repair that bad boy for you.

Alright so I know what caused this problem, I used framaroot to root my phone then unistalled the app. When I uninstalled the app thats when I started having this problem. So im going to see if the dev of framaroot can help me out
Earlier today I wanted to move some files about on my phone in preparation for a wipe and reflash. I managed to copy off a backup I made. Suddenly, the USB disconnects. Thought the cable may have simply disconnected, I proceeded to unplug and replug my phone, but no dice. The phone seems to charge, but USB connection does not initiate.
I tried rebooting both machines and reinstall USB drivers, but still no connection.
I ended up giving up for a bit and played a game for a couple of hours. Weirdly, during this time my phone happily connected, providing the USB options in the notification area.
I ended up unplugging my phone again, but when I plugged it back in a few moments later, it did not connect. It's since been connected for around 15 minutes, with absolutely nothing but charging occuring from my phone.
Any help would be a appreciated.
Thanks!
Edit: I have also tried numerous cables.
I've also encountered this problem, look for something called 'MTP fix' and see if that works!
Sent from my GT-I9100 using xda premium
USB port/board on the fritz. Replace before it dies completely (you won't be able to charge/etc). You need to work out which revision of the board you currently have in the phone & buy the same board (cheap; eBay/etc) & swap them out.
Search for similar threads, there's been a lot of discussion here about this issue/which board you need how to replace over the past few mths (including photos).
Aw crap.
I'll try the MTP Fix suggested above, but if that doesn't work I'll look into this. How difficult is replacing the board?

Hey There.
So i got a small problem. When i connect my phone to my computer with a misro usb (not 3.0) it doesnt recognize the phone at all. Normally on the phone it will show its in Camera or MTP mode oin the pull down menu but now its not showing anything but it does charge the phone. Did i hit a setting somewhere i didnt realize?
Any help is much appreciated.Been on the site quite a few times just reading the wealth of knowledge. First time ive had an issue where the answer isnt already posted here lol.
Thanks
But you're saying it does work with the original Samsung 3.0 USB cable? Then that would mean the phone doesn't like the other cord for some reason. Samsungs can be picky like that sometimes. Check the Device Manager for driver errors and try other ports, cords, and computers to make sure it's not a new issue with the phone's USB charge port.
