Today i plugged my phone to the usb cable and instead of getting the usual connection option screen... nothing... The phone charges but no Data transfer. Did hard reset, still nothing.. now im stuck with the old firmware... any help plz?
might be the cable that you're using. i used before a cable that is not the original and the same thing happened to me, i.e. pc cannot recognize device.
Try Settings-->Other-->USB To Pc-->UNCHECK (enable faster data sync) this should help...
cable : original came with the phone (used to work up until b4 yesterday) also tried another micro usb cable that came with me N900 but still nothing.
I did the un-check "enable faster sync" still nothing
Did soft reset, hard reset using volume keys, and factory reset from phone setting itself. still nothing.. the phone charges.. but no data transfer.. its something to do with the phone because i tried multiple PC's the phone doesn't bring up the connection type option page

No harm in checking.Infact i faced similar issue once and the USB2 was disabled.It took me an entire week to diagnose the problem.These PCs have got a mind of their own and do mischievous things on their own without our knowledge.
But since its not working on multiple PCs,i am not sure.We'll hav 2 wait 4 a solution i guess...
hmmmm.. would a full system format and re-install be possible? and would it fix it? (talking bout on the phone)
HELP, HELP
SAME PROBLEM WITH HTC2 T0MOBILE
even on the boot loader screen, it charges but no USB stuck on serial.
even when on sleep mode and plug the cable orange led is on but it didn't wake up for choose (active syn or stoeag memory)
PLEASE HELP
i can do nothing, HSPL or rom upgrade
the cable and the USB drivers are tested more than 100 times
Most horror problems I had with the USB sync have been down to not having the latest version fo Activesync from microsoft. Uninstall the old version thwen reboot - now download the 4.5 version which I think is the newest and last version they made (unless im out of date) and then reboot the machine, then connect up the phone - but not immediately after the machine has booted wait a couple on mins, Windows takes longer than it often appears to be ready to go. One your hard drive led flashing light has settled down it is probably time to try. Then see if it finds all the devices in your phone.
If it doesnt go into the control panel and double click system, hardware tab, then select device manager and see if there are any devices with a yellow sign with a "!" in them. If there are delete them and then unplug the phone and plug it back in again. It might get past some stuck things. If it doesnt see anything new on device manager theres a menu at the top and look for "scan for hardware changes" this gives teh device manager another look at what its got connected.
If that fails open up the USB section under in device manager - its got a little plus next to it, press that plus and it open up all the names of chips you have for your USB control on the pc's motherboard. Write down the numbers and go and get the correct up to date drivers for that type of USB and install them. Then try the process again. Sometimes deleting the USB drivers and just doing a "scan for hardware changes" again, will reset the USB drivers and start things working, however it can get tricky if your using USB mouse and Keyboard to select anything if you delete the USB, because thats what the KM/mouse relies on to control teh machine, so have a PS2 mouse plugged in if you can. If that fails I would suggest reinstalling windows as its probably knackered. It amazing how things start to work wonderfully on a fresh copy of windows.
I have been where you are! And tried every suggestion that was given here. It all came down to the cord. I actually went through 3 different cords before I found one that worked and found that by accident. I bought an external drive and that cord works. For whatever reason, that is the only cord that now works for me. I only use it for data transfers. i use the other cords for charging.
Today I deleted some programs off my SGS2 that were in the list in the SGS2 General Forum. My phone was able to connect to the PC before that. After I uninstalled the applications on my phone, it no longer tries to talk to my computer. I have reinstalled the drivers, restarted both my computer and phone, and still nothing. I am worried it was something I uninstalled but I doubt it. I was quite careful removing the programs using Titanium Backup and they were completely unrelated in my opinion. I have a feeling it is only coincidental.
Anyhow can you please help me troubleshoot what has happened? Thanks.
Perhaps it wasn't related. I figured out how to do it with USB debugging ticked. I never had to do that before. Originally it would connect automatically with USB debugging unticked. Now it only connects with USB debugging ticked and after I say that it is 'OK' pretty much.
Still, if anyone can shed some light on what I may have uninstalled let me know. Thanks.
may not apply to you since im guessing you tried it both times on the same comp with the same OS. i find that kies hates 64 bit OS. it just wouldn't connect on my desktop running win 7 ultimate 64bit but connects just fine on my laptop running win 7 enterprise 32bit. anyway... i usually have debugging mode on anyway, much easier for me to access the phone and sd card using explorer instead of stupid kies. kies i only use for firmware updates or atleast until i've rooted this thing.
Sorry I should have mentioned that I am using Windows 7 Professional 64-bit. Thanks, shabs52. Good to know it could be my OS that is fumbling. I would have to agree as well, Kies stinks. I can't wait until I can get a stock OS without any crapware.
Anyhow it is strange how it worked for awhile and just stopped, but debug mode is better anyway.
Win 7 x64 Kies failed always .
Wiped drive brand new Win 7 x64 install Kies no problems = bad driver install or conflicts on original setup .

I'm having this problem too
Despite my Win7 64bits, Kies always connected automatically, both with SGS2 and my previous SGS. Yesterday my SGS2 started to behave strange: when I plug the USB cable it doesn't recognizes automatically (takes a few seconds), and only starts charging the battery, but the data link is not stablished (Kies won't even recognize there is a device connected). When I remove the USB cable the charging indicator continues to show as if it still was connected (again, for a few seconds). The same with the power cord. Since the symptoms were the same in my notebook (also Win 7 64) I tried it on a Win XP 32 - same thing (different USB cables). This makes me think the problem is with the device itself. Anyone have seen this?
Try deleting the drivers on your pc for samsung usb while the phone is unplugged. Then plug back the phone and windows 7 should automatically search and install the required files...worked for me with w7 64
I already did that, but the problem persists. Today some new symptoms "arrived", which led me to this other thread (http://forum.xda-developers.com/showthread.php?t=1151863). The phone eventually enters car mode, or beeps and shows the charging indicator (even though it's not plugged). Weird. Will take to service tomorrow.
Im having this same problem with my epic touch. Was just wondering if anyone found a way to fix it.
Hi mates,
since this evening, my Galaxy S2 (unbranded, unrooted, with stock firmware) was connecting fine with my PC in the "kies mode". I could use kies flawlessy, and I could regularly see my phone in my windows 7 (x86) explorer, and use explorer to read and write files from and to its memory.
Then, this evening, I got a notification, from kies, that an update (of kies) was available (2.0.2.11071.182.2), and I gave my consent to the updater. It did all its dirty job but after the installation of the new version, despite the phone connects via USB, every time I try to access the phone's memory from the PC, the connection drops. It restores backafer one second or two, but then again, if I try to access the phone's memory, it drops agains. The problem appears indifferently when accessing phone's memory from kies, and when doing it from windows' explorer, and this makes me suspect of the drivers, that the new version of kies brought along.
The phone connects correctly to the PC in the direct USB mode, and I can access its memory with no problem, and this also suggests that the problem should be the drivers.
So I uninstalled everything (new kies and drivers), and rebooted the PC, then I dowloaded what I believe is the previous version of kies: 2.0.1.11053.99.3, and launched its installation. After the end of the process, I rebooted the PC, just to be safe. According to the list of the installed software in my PC (in "Control Panel > Uninstall a program"), the drivers have rolled back, as expected, to version 1.3.2410.0 (before they were 1.4.something).
At the first connection of the phone to the PC after the reboot, I got notification from windows that the device installed correctly and it is ready to use (all the tree drivers are indeed reported as installed correctly)...
The point is that all this did not solve the problem at all, and USB connection still behaves exactly as badly as before.
I tried again uninstalling and reinstalling everything, also adding a manual clean up of the windows' registry from any entry related to "samsung", checking that the phone was not set in "USB debugging" mode, and disabling the antivirus, but despite everything appears to be fine, the phone regularly keeps on refusing to maintain USB connection alive everytime I try to access its memory.
What drives me mad is the fact that until this evening, everything was working flawlessly!
What else can I try????
I've just made a test on another PC running windows XP, with latest Kies 2.0.2.11071_128 installed. It's my office PC, and although I'm not 100% sure, I seem to remember that, until yesterday, my phone was connecting fine with it, and with that version of kies. But now, all of a sudden, I have the same problem also with this PC...
So, likely, it is a problem of the phone... the MTP application restarts everytime I try to access the phone from the PC, so... what can I try on the phone, to see if I can fix this annoying issue? I DON'T WANT TO FACTORY RESET MY PHONE, PLEASE!!!!
If any of you has any suggestion, I would be more than grateful...

I had the same problem the other day and I could not find a way to fix it, in the end I did a factory reset from Settings/Privacy and its ok now, just wiping cache did not fix it, factory reset was needed.
Dear Odia, thank you very much for replying and giving me a clue.
So... it appears that there's nothing else to do, is there? Buhahhaa!!! I want to cry!!!! I haven't made a backup and resetting the phone will be really painful... I'm already starting to feel the pain in my ass!!!
By chance, do you happen to know if I will have to buy again the apps I have already bought from the market? I have always kept both "Backup personal data" and "Automatic restore" ticked in "Settings>Privacy"... Could this be of any help?

You can always make a backup now before the reset and you will not have to buy paid apps again.
Yes but how can I backup my phone if kies will loose the connection with the phone as soon as it tries to access its memory?
Oh wait a moment, Perhaps I could use Kies air? Deos it allow to backup the phone? 'cause I can't test it now in my office, there's no wifi here...
From what I can tell, its the amount of the power that is supplied to the USB port itself that is the issue. I have the same problem when I put my i9100 on certain computers. Same thing happens to my WD MyPassport. Certain computers it works fine, and some it will power it for a bit, but once the device starts to draw too much current, it just disconnects.
This is why I try to do all my modding and flashing on a laptop, since, for me, they seem to be the most reliable in keeping devices powered up properly.
This is certainly a good point, but in my particular case, USB connection used to work up until yesterday with all the PCs I have (2 laptops and a desktop PC), whereas since yesterday, it works with none (with and without using the same USB ports). In addition if I use straight USB connection (hence not through the MTP app used by kies), it works fine.
Anyway what you have just mentioned is actually what scares me, because it would mean a hardware fault. But I'm crossing my fingers, hopefully it's (just) a software related issue and a factory reset will solve it. After all, straight connection works, so it would be really surprising if it were a hardware fault.
I will try resetting everything when I get home. Another "nice" busy evening to account to Samsung!
I guess if all samsung customers were honestly paid for every hour spent mending/fixing the issues of samsung products, the company would declare bankrupt in a matter of a few days!
Ok, I solved the issue with a drastic factory reset.
Thanks Odia for helping.
I spent 8 hours backing up and restoring everything included all the settings and personalisations. I went to bed at 3 am, eating only a quick sandwich in front of the bloody phone.
THANK YOU SAMSUNG, I wish to electrocute all your ****ing managers.
I hate when something in a device screws up all of a sudden and noboby knows why. It could happen again any time, and again I would have to spend hours mending a stupid phone instead of enjoying my life.
By the way, does anybody knows exactly what data is automatically backed up and restored on google servers by these functions?
"Settings>Privacy>Backup of personal data"
"Settings>Privacy>Automatic restore"
I always had both tiched, and I noticed that almost all the applications downloaded from the market that were installed on the phone, were automatically re-downloaded and restored on the phone at first boot after reset, but I'm not too shure I have understood what else was automatically restored.
I just read this thread for the first time, and was sympathetic to your issue when I started reading. I could see that there had been problems, but suggestions had been made and you seemed to be making good progress.
I was getting ready for offering advice and wishing you well with your problem.
Then suddenly you start to wish physical harm on Samsung employees.
Bye.

This is a simple solution try it and it will work for you the next time you face it most of the time it is a hardware issue i have been facing the same issue and nothing helped neither the factory reset nor the *#7284# procedure.
Take a pointy object like a pin or a paper and then clean your usb slot of the phone properly cuz most of the times usb pin points gets connected with each other due to the atmosphere and metal reaction. After that it will work like a charm for you. Before commenting anything negative i would appreciate if those who are facing this issue for a long time try this and then comment
Had the same problem, solved it by upgrading the phone software.
Setting > About Phone > Software update.
No need to afraid losing files. Hope that helps.
i faced the same problem on the GalaxyS sometime back. i did factory reset too. I got the same problem again. but i remembered it working on my LG TV so i did not go for factory reset. I went for re-install of samsung's USB driver for Windows. now it is working fine.
I fully agree that Samsung needs to be more responsible and responsive in resolving the such problems without causing data losses.

You could have saved a lot of hassle by installing a custom Rom and Kernel. I hate MTP mode! Mass storage mode is much better, I never had any problems with that....
Workaround - Power Management
This may be fixed, for now. However, in the future, there is a small workaround that you can use so that you're not required to wipe your phone every time this happens.
Here's what I do:
Since the device's connection is severed after the use of a certain amount of power, we can control the power management of the port that the device is connected to.
On WinXP:
Enter "Control Panel" > "System"
Click on "Hardware"
Click on "Device Manager"
Find the "Universal Serial Bus Controllers" section
Click the "+" next to that, and find the "USB Root Hub" that the device is connected to.
Right-click on the Hub, then select "Properties"
Click on the "Power Management" tab
Then, UNcheck the box that says "Allow the computer to turn off this device to save power."
This will prevent the connection from resetting. It's a quick workaround that works pretty well for me.
However, I ought to note that the changes should be undone after you're done with syncing the device, ESPECIALLY if you're on a laptop. Otherwise, you could risk a lot of battery/power usage within a short time, even if there is no device connected to that port.
Good luck, I hope this helps.
Cheers!

Please don't bail out because of that comment, i have been having this issue for a month and AT&T almost sold me another phone telling me it was the USB PORT.
I changed my phone setup dialing *#7284# and changed the UART to : PDA from Modem and same for USB (to PDA) modes. This helped get connected as before it would not even recognize the phone (computer would not do so).
I was am not sure if it is not the battery or charging circuitry, as others also reported, but my charging circuit is working fine and my battery charges 100% and last all day as normal. I can connect to the USB port and see my phone for a short while but it will suddenly disconnect.
But same as before it suddenly disconnects and will reconnect cycling continuously. I also believe it is the charge circuit because when it is charging, i hear the phone constanlty beeping from turning the schreen on/off. Same as when it is plugged into the usb port on computer.
Am tempted to buy a battery, but is can run the phone on the USB port without a battery in the phone. Problem continues without a battery...disconnecting and connecting to the computer.

I was plagued with this same problem, until I tried the above fix, and it works brilliantly! No more disconnects, great stuff.
It's pretty old topic but maybe someone has same issue and doesn't want to loose data. I had similar problem (couldn't connect to device, also couldn't install/uninstall any stuff because of no-space-available error).
I managed to download all pictures/documents via adb - worked pretty well. A sample command to retrieve all camera pictures:
adb pull /mnt/sdcard/DCIM
I have an HTC ONE X+ and it will not connect to the computer nothing happens, it will only charge.
I have tried to connect it with and without debugging on. I have tried connecting it after uninstalling sync manager and even reinstalling sync manager to the latest version and it still will not connect, I get no acknowledgement from the PC or PHONE (except for the phone charging). I have connected it to 2 other computers and still no response, I have tried another USB cord and still nothing. I did connect my other HOX and it connects just fine but my HOX+ will not.
Any suggestions/solutions?
Drivers?
Install this drivers from Hasoon's Toolkit Thread and try it again.
You may also want to uninstall the HOX drivers as they maybe causing a conflct and remember to have the screen unlocked while connecting (helps my device, no idea why).

I figured out the "port" on my was bad. Got a replacement phone under warranty and all is good.
OK so, I recently decided to use my HTC One M7 as a "Modem" in this case, Tethering thru my Computer to my Main Modem, as my Computer keeps getting "DNS unavailable" stuff. Works great, only problem is that it freezes parts of Windows.
The Windows Task Manager doesn't load and is frozen (Usually doesn't when the CPU is under excessive load), the ENTIRE Control Panel of Windows is unresponsive, anything that has to do with Windows is not working, when it's unplugged they start working again.
Is this a problem with my Phone? or my Computer, It for sure can not be the computer as it works when it's unplugged.
Thanks!

update your USB drivers and chipset drivers and see if it continues
