Hi,
I'm having a real though time trying to connect my galaxy s1 to a pc. Have tried everything, like kies, direct connection, reseted the device, and no joy.
When I plug the cable it makes that sound as it is connecting but it doesn't show in the PC anywhere, nor even in Device manager.
It can get pwr from the usb cable when is connected; already tried with another cable and same thing.
My final goal is to unlock it.
thanks for any help
have you tried put yoy're phone in depurating mode?
I guess yo mean Debugging mode, as I couldn't found Depurating anywhere. Have selected it and the same effect
HI

#Samsung Kies always makes problems on Windows x64 !
##I would recommend, if you got 32-Bit Computer, to use that ;-)
#If you Want just flash over Odin, then is this driver package enough

Hi there.
By direct connection you mean the USB Mass Storage mode, right?
It might be some weird, random problem with the samsung system drivers. I used to have such problems about two years ago, back in the days of Froyo. Have you tried re-installing them? There was a link to proper drivers file in one ICS installation tutorial, and those drivers can be downloaded here. If you go about trying this method, lemme know if it worked.
Cheers.
PS: Unlike diklooc there suggested, do not never EVER go back to x86 OS. That's the worst advice. Kapisch?
Did you check your usb port in System ?
Sometimes it stuck with another lastest device
Hi,
have tried everything, and finally only in a WinXP32 could be abble to get the error shown on the file atached.
But nothing (warnings) come up in Device Manager
Unninstalled everything (kies) and tried to install only the driver and nothing happens.
Should I try to mount it on a linux?
or is it dead?
thanks
i have this problem too
wat chan I do???
my sgs can not connect to my PC
This may help...
Hi there - I don't have the same phone as you, but I did encounter the exact same problem. I've been searching around and it looks like the most common fix was to simply replace the cable. I don't know what kind of cable you have, but my phone (a Samsung Focus i917) uses a mini-usb connector. I found that my Amazon Kindle used the same connector.
When I was using the Samsung cable, I'd get intermittent connects and charge power. The OS would report unknown device. When I switched computer's = same result. I switched to my Kindle cable and the computer instantly recognized the device and installed the drivers. After 12 hours of troubleshooting, factory resetting my phone (blah - lost everything) it turned out to be the cable. I know that this isn't an easy troubleshooting step for most people, because who has an extra cable? I just got lucky that my Kindle uses the same connector. I'm now suspecting (due to the prevalence of this connectivity problem coming from people with Samsung phones - there are a LOT of reported issues) that there is probably a Samsung cable problem in general.
Good luck with your phone.

Nasdriver, I currently have a similar problem but mine is related with Samsung Kies as I can't get either my older SGS1 or my newer Samsung Nexus to get recognized by Kies. I also suspected the cable thing and even read it could be a USB port issue but neither of them was my problem (I have 3 cables and 8 ports on 2 computers that result in the same thing). I can connect other devices with the same cables and they work, so I suspect my problem is focused around the Samsung device drivers.
My advice is if you can go in a systematic manner, first focus on the cable (easiest to replace), if you get the same results with a new cable, then focus on the USB physical port, clean it with some Isopropyl alcohol, if the port works for other devices (camera, other phones, etc..) on the same cable but not with the SGS, then try reinstalling the samsung device drivers.
Oh, and if you want to unlock your phone, the EASY way is to download the Galaxy S Unlock application from the Android market (no affiliation) it's free (but the developer does accept donations) and it WORKS. I won't bore you with my 3 week journey trying to unlock my Bell SGS phone here in Canada, had I found this app first I would have done it in less then 2 min saved myself a LOT of frustration.
Good luck

This is a new problem for me.
After successfully sorting out all the troubles of connecting SGS to KIES, and been using it happily for almost a month, now I'm facing another trouble which is quite big this time.
Windows Vista (32-bit) and Windows 7 (64-bit) are now can't recognize the phone when connected through the USB. Got a message says the USB Device/Hardware Is Not Recognized.
I'm using the SGS original cable. The cable was working perfectly and now suddenly it doesn't work in data mode but still able to recharge the phone battery.
Am I having a cable problem? Or worst, the USB connector (on the phone) problem? I tried to clean the USB connector on the phone but still can't connect the phone to my computers.
Does anybody here having the same problem as well?
I just gave up with my PC, same problem
In then end I set up a VMware XP machine to sync
Else I use my laptop

I sometimes have a problem with KIES detecting my phone. What I sometimes have to do is connect the phone with KIES loaded, go to device manager, show hidden devices then uninstall the phone (sometimes has error on device, sometimes not) then disconnect then reconnect phone.
Such a faff but using KIES to check for firmware update lol
This may not help ya but worth a thought, Im on Win7 64
I did not have any problem connecting the phone to KIES, I was able to upgrade the firmware from JF4 to JG4, and been a happy SGS owner for a month now.
But yesterday I suddenly can't connect the phone to any computers. My laptop (Win Vista 32-bit) said that a USB device connected is not recognized. I reinstall Kies in my laptop and same thing happen. Then I switch to my PC (Win7 64-bit), USB device not recognized also appear. Reinstall Kies, still no luck.
What I just realized is that there is NO USB Indicator in the SGS notification bar!
Does that mean that the USB connector on the phone going bad?
I still able to recharge the battery but the USB icon dont show up.
I am now seriously considering the quality of Samsung Galaxy S! Way too much problems for average owner, and even for savvy owners this is just over the top!
What should I do now?
Find another computer or install VMWear and see once and for all if its your phone at fault. Also worst case do a factory reset. If no go then you might have a hardware problem. You could always try Mass Storage mode and see if you can mount the phone as external drive. Its not really the phones fault but I would say its KIES, its just a piece of ****. I have never been able to connect to it using 3 computers and I would say I know what i'm doing since I work in i.t. Also did you replace your Launcher recently? As KIES needs TouchWhiz as default launcher to work
I just tried to connect SGS to another laptop (Win XP 32-bit SP3, no KIES though). Same thing, the USB device is not recognized baloon show up and no USB indicator in the SGS status bar.
I'm going to Samsung Service Center, after calling them, they suggest me to bring the phone to the nearest Samsung Center. They said that this is not the first time and also said that the problem might be the connector or the cable.
have you read this ? http://forum.xda-developers.com/showpost.php?p=8107646&postcount=50
Seems kies has a bug where it can't work with files with 16chrs or more.. Told ya KIES is a piece of ****
Yes, But did you try the Mass storage mode
Settings/About/USB
I always just use Mass Storage mode to xfer files. KIES is crap.
As I said previously, my SGS has no problem at all connecting to Kies. USB Mass storage is working perfectly as well.
The problem I'm having now is the hardware (the cable or the interface) I guess, since I still can recharge the phone using the charger or the USB cable.
ps. I'm using Kies from Australia, the 1.5.1.10083.
Have you looked at the pins on the phone? are they screwed? Can you somehow find or burrow another Mini-Usb cable to test ? I have heaps as some of my external hdd's use mini-usb but you might have to buy a new cable.
Try this.. I wrote this a while back.. It may help. I know you suspect it's hardware, but it might be worth trying anyway.

Thanks for the help guys!
It's purely hardware problem. Yesterday I brought it to local Samsung Service Center, and because they said this is not the first timer, the technician quickly open the device and gosh... dust and some fungus were collected near the microUSB port! I admit I never close the USB port, just left it open after use, my bad!
After some cleaning and testing, the microUSB is working again.
Now I'm a happy SGS user again!
but that doesn't explain how it works on one Windows (Win7) but not on another Windows (WinXP)

The SGS wasn't recognized in ALL Windows versions, since it was a hardware problem.
Now SGS is recognized in ALL Windows versions.
download "usbdeview" and delete the usb drivers for the specific device.
After failing again and again and again, reinstalling the drivers, reinstalling KIES (which simply won't work on my machine), removing the battery etc. etc. etc. I just don't know what there is left to do...
When in Win7, the phone is recognized, although Windows tells me that it's not connected to a USB2 hub. In download mode it says connection failed. What else am I supposed to do?
The phone is not branded or anything, applying stuff though update.zip's was never an issue.
So please somebody help me - I'm stuck with JF3
simple, switch to another computer
unless you can find and easy way to make windows forget the USB bugs
you need to also unplug the PC and wait for the PC to power drain, reconnect the PC power cord, and turn the PC back on.
after it goes back to windows try hooking up the phone again, if you get the message about not running in USB2 mode, then it failed
retry after resetting BIOS settings, installing USB2 drivers, etc.

I had a similar problem...
I had a USB 1.1 Port on my Thinkpad T22 and the drivers didnt like it
Use a different computer/USB port
...btw I still like JF3
Now you will probably feel the urge to smack my head against the wall when you read what I'm about to tell you... I don't blame ya... The cause of the "problem" was that I wasn't using the original Samsung USB cable that came with the phone. I just couldn't find it so I decided to use an aftermarket cable which I had lying around. Big mistake... I finally found the USB cord and that fixed everything for me. Beware of aftermarket accessories as the phone will punish you for using them!
that cable might have been a very poor after market version then
i do use a couple of after market USB to micro USB cable with the phone and it works fine
there are bad aftermarket products
and there are quality aftermarket products
I remember having a few mini USB cable with my old G1, and had similar problem. With one cable it was recognising, with the other one didnt.
Don't know what difference they have, but it's indeed wierd!
I was using a nokia usb cable to flash my samsung
Since upgrading the Galaxy S to 2.2.1 which I absolutely love - must faster than anything previous, sleek, really well done, I've just noticed for the first time that my USB doesn't seem to work.
The computer sometimes sees it but just says the device is malfunctioning, the phone sometimes sees the PC and gives a menu for "ask on connection", but Windows just does not know what this device is at all.
Suspect I may have to reinstall the drivers fully in Windows, remove it completely and try again, if it actually showed up as an unknown device in Device Manager.
I do need to try another PC and cable just in case, but this is what Im having at the moment in Windows:
USB Device Not Recognized
One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it.

Factory reset the phone, but the USB port still is not working. Charges fine, but don't connect over USB to the PC.
Can it be in debugging mode. Try to switch between mass storage and kies.
Probably you have checked that already..

Now i am looking to install untouched rom in order to give it to service but when i am trying to flash from recovery i get an error . Any suggestions?
This may sound dumb, but it could be the USB port acting up (loose connection). Try wriggling the cable around or use a different port.

Right, I've tried all available USB ports, two different computers, two different OS's. The phone just does not register a USB data connection. It only recognises AC charging according to the logs.
I think I have a broken USB port on the phone as if I jam the connector in at an angle on the phone, it sometimes registers the data connection but its far too unreliable.
Development mode don't work, Kies, Mass Storage etc... anything. Nothing works.
Factory reset doesn't make it work.
I can't even flash a new ROM as the phone is not detected in download mode.
I've got the phone booked in at a Samsung Service Centre now. I've seen a few webpages referencing corrosion. I tell you what though, this phone has been protected way way more than my old N97. I've had so many phones and not one has suffered from "corrosion". So let them just try and say it's my fault. Im ready for em.

Try cleaning your phone usb port. A guy named omersak had the same problem, and he had solved it. Search for the thread started by him, and how he has solved it.
I hope you can solve it without going to the service centre. And good luck.

Definitely trying that first - thank you to all the people that have been doing the investigation.
It sounds to me like Samsung have got a bad batch of USB connectors that should be replaced under a factory recall.
I don't use mine in a shower, or sauna, or anything like that, I don't even use it in the rain.
The closest it gets to any humidity is being in my shirt pocket from time to time.
Im going to get some meths or something like that and some thin paper and see what I can do with that. Im just off to Homebase!
there are similar problems on the galaxy 3 series where usb suddenly stops working. the following solutions seem to work there:
1. dial *#7284# to open "PhoneUtil"
2. in USB section, switch to modem, and then switch back to PDA
if that doesn't work: reboot into recovery and select "wipe cache partition"
*hth*
I've tried both of those before I start splashing the methylated spirit around. Still no joy.
Wipe Cache don't work, as well as wipe data/format sd/restore factory defaults etc.
I think I've got a 100% hardware fault.
@OP,
I am terribly sorry about your case. Looks like you need to make that trip to the service centre.
At least you have tried out every possible means known.

I'm not an Expert but 2 hints from me:
1. If you have'nt tried yet: Install usb-drivers on pc new and then connect your phone and wait until drivers are installed to your phone.
One times this way worked on my i9000.
2. Look for a zipped rom on xda which you can directly download and install from sd-card.

Argh, I am pulling my hair out trying to solve this! When I connect my phone through USB to my computer my phone detects the connection but my computer doesn't respond at all! I bought the phone used and it is already rooted but is using a pretty old rom and I wanted to upgrade it. It is currently running "Kernel version: 2.6.32.9 [email protected] #4".
Things I have tried:
Using different USB settings on the phone (Kies, mass storage, ask on connection)
USB debugging mode
Different USB cables
Different computers
Cleaning the micro usb port on the phone
Formatting SD card
wide data/factory reset
Nothing seems to accomplish anything, it still reacts in the same way.
Any help would be greatly appreciated!
The ROM shouldn't count.
First of all, has it ever worked? I just presume you're running on win7: did you installed the drivers as specified in several different tutorials on this forum?
What kind of connection are you trying to establish? tether, usb, kies, other? have you tried any combination possible?
I just got the phone a couple days ago, I have not managed to get it to be detected by anything yet. I have tried it on a couple Win 7 boxes and also a Vista laptop. I am currently downloading Ubuntu just to rule out the OS factor. I have just been using Kies to install drivers although after reading your post I found this thread:
http://forum.xda-developers.com/showthread.php?t=961956
I'll try that and post results if that is what you mean? I have been trying to establish basically any connection at all for the ultimate goal of getting Odin to actually detect the phone so I can flash it with ClockworkMod Recovery and then an ICS rom. The phone detects the USB cable fine and starts charging and puts the phone into whatever mode I want (kies, mass storage, etc.) but the computer has yet to give any indication that anything is connected to it.
Try with the drivers, but be also sure to enable usb debugging to be able to select a different usb sharing when inserting the cable in case you haven't already.
The drivers installation didn't make any difference and I've tried USB debugging and all 3 connection modes (Kies, mass storage and media player), none of which exhibit any response from the PC.
Edit: Posting from Ubuntu now, same exact thing. Phone detects USB connection, and it doesn't matter which of the connection options I choose as the PC doesn't give any indication that anything has been connected to it.
That's really weird. Does Odin3 (which presumably works at a lower level) sees anything if you put the phone in download mode? ) this way you should be probably able to upgrade somehow.
Sent from my galaxys using XDA App
No unfortunately there is no response from the computer or Odin3 when the phone is in download mode and connected through USB.
that's odd and maybe that's not good at all.
I'm starting to think the problem could be hardware related, especially in a situation where odin can't see the phone in download mode (i.e. no software layer is interfering).
Is there any glaring damage/scratch/missing parts on the usb port?
Sincerely, if I could return it I would try that at this point.
Unless someone else has got anything else to try.
I'll take a good look at it under a scope when I go to work on Monday I guess. Thanks for your input, I'll try to update if I find out anything else!
So I took a look at the port under a scope today and discovered that one of the pins (the middle one) in the micro usb port on the phone seems to be completely gone! Not sure what each pin does but I'm assuming that one is probably used to communicate to whatever the phone is connected to...
Luckily I have access to a parts phone that I can take apart for a replacement port so probably tomorrow I will attempt surgery on the phone! Will report back with further progress after I have done so.
Well I'm happy to report that that was definitely the problem! I replaced the micro USB port on the phone today during my lunch break, put the phone back together and plugged it into a PC here. It immediately detected the phone so I'm pretty happy! Guess I'll be trying out some ICS roms tonight when I get home!
that's great, glad you managed you fix this yourself, well done and enjoy your SGS
Hey all. Just got my Galaxy S4 today and I was loving everything about it until... right now. For some reason, the darn USB won't stay connected to the computer. It doesn't matter if it's simply plugged into the computer as an "installer" or as a media device. It'll constantly disconnect and reconnect itself, even when I'm not transferring any files.
It's not the my computer/USB ports, either, since I can transfer files between my HTC Thunderbolt and Nexus 7 fine. I've also tested 2 other USB cables and they all behave the same way.
Anyone know what's going on? Did I get a lemon?
No im in the same boat. Was trying ti connect in today. I reinstalled and un installed the drivers about 4 times. Tried un selecting usb debugging in developers menu. Installed kies and used the drivers from it still no good. Used 3 different usb leads. Phone will still charge from pc and even when im installing the drivers again and connect the phone it will say that your new device is ready to use but still cant access phone, it simply does not show up.
Wouldn mind was working 2 days ago fine. Same usb port and all. And the port is fine cause my old s3 still reads from the same port.

Same problem
I have also been dealing with this for a while now. I have Windows 7 64bit and I have reinstalled the drivers many times through Kies and manually. It seems like the problem is getting worse since initially I could do some file transfer through usb if i fiddled with the device (changing usb ports, unplugging it, etc). Now I am hard pressed to get it to show up on the computer through MTP at all.
This is quite annoying since I am developing an android app and I need a usb connection in order to test it. A fix would be awesome.
I just tested on my sister's laptop and it doesn't have this problem. I clicked around the phone, transferred a 10gb movie, and left it plugged in to see if there were any signs of disconnects. None whatsoever. Odd. Maybe Galaxy S4 just doesn't like something with our computers. This is quite annoying.
I have a fresh Windows 7 64-bit partition I installed the other day so I'll test it out on that and report the results later today.

Oops, missed your post. Unfortunately, it disconnects regardless of the phone's state.
My friend's S4 was doing the same thing on his desktop. Every time he would try to transfer pics the phone would disconnect after a few files.
I tried different things from reinstalling drivers to trying to only copy over a couple of files at a time, nothing worked.
Finally I plugged his phone into one of the back usb ports and transferred over 2gb with no problem and no disconnects since.
My guess is the S4 is a power hog and some usb ports just don't supply enough juice. Try plugging it in to a usb port that comes off a motherboard. Don't use the front ports or usb hubs. Hope this helps someone.

On my dads PC sometimes it would display OK and other times "usb device has malfunctioned" (didn't try the rear USB port)
On my work PC it works fine on the rear ports.
I was having the same problem a few days ago, but then I reformatted the SD card, now everything seems OK.
Even the stock gallery app works now...?!
Guys I was having the same problem. For the life of me I couldn't figure out why suddenly my S4 wasn't being recognized by my computer. I finally went into developer options and noticed a "USB Debugging - Debugging mode launches when USB is connected" was turned on. I de-selected that, connected my phone and now my computer recognizes it again. I hope that helps guys, it helped me.

This may be laughably obvious but I'm a former Apple user, which has it's own dedicated USB connector, so I forget sometimes with the Samsung S4, which has a standard (looking) micro USB connector that I need a USB cable that is enabled for syncing as well as charging...not all USB cords with micro connectors on the phone end will carry the data because I imagine Samsung has made their phone's connector require a different wiring in the cable.
I was pulling my hair out yesterday trying to figure out why the computer wouldn't see the phone..then looked at the USB cable and realized I'd plugged a non-syncing cable in. I tried the cable that came with the phone and bingo, worked like it was supposed to.
Hope this helps, sometimes it's the little things we overlook that drive us nuts.
Any way to connect in master storage with out root.

Use a different usb cable and usb port. I know it sounds stupid but there has definitely been phantom problems which were solved this way, even with something as simple as adb commands
i have same problem. trying all the way but always with the same result...
