Hello,
I'm having a problem with the S4.
When I plug it into the computer (Running Windows 7), the device starts charging and I can sync files with the device.
But, it starts reconnecting, the USB connection just keeps disconnecting and connecting over and over again, nonestop.
But the device is still charging, only the connection to the computer stops.
Its going back and forth drom cd installer to mtp? Drivers are installed?
Does someone know what the problem might be?

I had a similar issue, the problem was damage to my USB ports. Try different ports.
When this was happening to me I found the problem to be the cord I was using, with the littlest of bumps it would loose connection. Try swapping to another cord and see if it fixes your problem.

^ This. I've got quite a few cables that I cycle between for different instances, and there are one or two I have that seem to be really finicky.

Don't know why it happens but ROMs like jellybeans4 bypass the installer and go straight to mtp which fixed it for me.

I had a similar issue where it would constantly disconnect and i could never get it to connect long enough to get past the installer, but it only happened on my desktop and on all usb ports, so i rooted using my laptop which didn't have the problem, and installed Hyperdrive, and now i can connect to my desktop just like i was before, but without all the disconnects. so it seems like it was a combination of my phone and my desktop not getting along nicely, but with a custom rom everything is fine.
Ahh now that I think about it the newest Samsung USB Drivers might help him also.

So, I just got a HTC HD2 and am trying to connect it to the PC. By the way, did the TMOUSA HD2 ever come with a cd?
I have a vista and tried to download the Activesync 4.5 but it won't allow as I am suppose to download Windows Mobile Device Center. So, I download WMDC and installed it. I plug in the phone and all I get is "USB Device Not Recognized" . PC doesn't detect it.
I have searched everywhere and tried everything but can't seem to get it going. I haven't anything solid to get it to work.
I tried:
-reinstalling the WMDC
-check and uncheck "Enable faster data sync"
Anybody have any idea? TIA
Is the phone charging LED lighting up when connected?
Have you tried another USB cable and/or another computer?
Then you could boot the phone up in Bootloader Mode. It will say 'serial' at the bottom of the screen. Then plug in the USB cable. The 'serial' should change to 'USB'. Then this might indicate that your computer is viewing the device as a unknown device. This device can be removed and your phone, in normal mode, replugged in.
This may not help, but it's worth a try. Vista has a known issue where it just stops recognising USB devices, even basic ones. Plug your phone in via USB and then restart the computer. When it comes back on it may recognise the phone. If this works then it will be okay for a while at least, but you may have to do this again every now and then.
Vista's basically a bug-ridden bag of gash. If you can, upgrade to Windows 7.
Hope this helps mate.

I tried with a laptop with vista (WMDC) and a laptop with xp (activesync 4.5). The led charging light is on, so it is charging but for some reason device not recognized.
I tried the bootloader (not sure what that does) and it says serial and then I plugged in the usb and it still says serial.
Still not working

I think I tried that already but I'll give it a shot again. At this point, I'll do anything lol. I was so stoked in putting android in this too
does any one think a hard reset might help?
It sounds as though the USB controller in the phone is damaged. I had this problem with my HTC Diamond, and searched for ages trying to find a solution. I manged to flash it with a couple of times with different ROMs (from the internal memory via WiFi) - this did not solve the problem.
I am sure that a power surge from a car charger was the cause of the fault.

try checking cabling first or change the cable
Same problem
I am having the exact same problem. My phone can charge on the computer but I cant sync of even access it via the "Disk Drive" setting. I have tried both AcrtiveSync and the Disk Drive option, unchecking fast data synchronization, reseting the phone, and reinstalling WMDC. I have Windows 7 with the latest updates. I have also tried connecting it to two other Win7 machine with identical "device not recognized" results. The phone and cable and practically brand new. Any help would be greatly appreciated. I'm at my wits end with this phone and it has been beyond frustrating.

Try another pc... buddy wid wmdc in it... go for win 7
Sent from my HTC HD2 using XDA App
I am having same problems have tried on a vista pc, my mac and mac running parallels, nothing works. Reckon it is as fred_up says, damaged usb controller which means no NAND Android for me.
Been having similar problems, but seems to have been less likely to occur if I click "Safely remove hardware" in Vista or W7, and remove the device - yes even Activesync (doesn't seem to be available in XP)

did anybody find a soulution?
hi
did anybody get solution for this? i m having the same problem.
phone doesnt sync with wmdc, nor connect as disk, only charges itself.
message appears "usb device not recognised"
i have done everything, changed cables, pcs, re installed wmdc, even flashed new roms using micro sd....nothing happened.
is this a hardware issue? why can it be charged but not synchronised?
pls help anybody.
Try another Cable. In my case, changing the cable works. Now i m using my HD mini cable with HD2 and it is working well.

thanks,
but i have already tried all that.
today i called a phone repair shop and they told me that
this could be due to two reasons.
1. usb port problem.-in which case it is replaceable for about 15 usd.
2. problem with an IC (?) of the circuit (guess the motherboard) - in which case
it is either not repairable or very expensive.
i ll keep posting as i go and visit the shop.
if there's another solution pls share here.
Some possible solutions to non-USB
Having come here via a search, I'll resurrect the thread with a brief comment. I'm having the same problem, haven't tried them yet but found several promising suggestions:

oops...had forgotten all about this thread, until today till i received the notice about new reply.
thanks for resurrecting the thread.
actually i went to that phone repair shop i mentioned earlier and they fixed it by replacing the usb port. still it didnt work with win 7 laptops. but was fine with xp laptops. dont know why...anyway i have said good bye to my hd2 long ago & using android now
guess lots of people are.
good luck to you all.
I've had this awesome tablet for just a day and loving it so far. Only issue I have right now is when I connect it to my Windows 7 PC, it is not detected at all. I have installed the PC suite (EeePAD_PC_Suite_v1_0_37.rar) which is suppose to install the requisite USB driver, but no luck.
It charges fine when I plug it into the wall so the wire is okay. Any ideas what maybe happening?

Most phones come with the drivers on them to install most functions when plugged in via PnP. I would test and see if uninstalling what you installed and then trying does. I could be wrong though. This is my first tablet and I don't have it in hand yet
i noticed that mine doesn't charge yet it does connect...make sure you restart too
I was told it will charge just at a much slower rate.
Problem solved. I did a bunch of things so I'm not exactly sure which one really fixed it. But rebooting the tablet seems to have done the trick. Also, the front USB ports on my PC have gotten a little strange. If I plug the USB connector all the way it wont work. I have to pull it out ever so slightly to get a successful connection.
Thanks for the quick response guys
No Matter what I install It still shows as an MTP device and that's it. Can not see it in any version of Windows.. any one have this issue. thanks
I got mine to work by using another cable.
My SGS2 keeps disconnecting and reconnecting the usb with my computer. This is hapenning for quite a long time now.
I keep hearing the windows connect/disconnect usb sound when my phone is plugged in, making it unable to recognize the device.
Today, it finally didn't had this problem for a while, so I took my chance to get back to stock ROM (because I need to send my phone to Samsung for camera problems). So I flashed stock ROM with ODIN, but I encoutered a problem: it didn't get further than the boot animation.
When I tried to reflash, ODIN didn't recognize my phone anymore, just like before. When I plug in my SGS2 to my computer while on download mode, it just keeps reconecting the USB, so the device can't be installed.
Tried a different computer. It kept being connected, but that comp sucks and it couldn't recognize my phone at all. My own computer also has problems recognizing the SGS2, but also has the problem that it can't stay connected.
Things to know:
- Other usb devices do stay connected, it's just for my sgs2
- I've tried different USB hubs etc., reinstalling Kies, uninstalling drivers.
- It does keep charging the phone, even when the computer makes the disconnect sound. That makes it even weirder!
Basically I'm seriously out of clues how to revive my phone
I don't want to send it to Samsung, scared of losing warranty.
You guys are my last hope!
to start the ball rolling, YOU SHOULDNT BE connecting sgs2 to a HUB, thats probably the fault, second, have you tried a different usb lead or a different computer with the same lead to either verify if its the phone or lead at fault??
No one on here can answer your question because it sounds like a hardware issue, wire or hub or charger port, but it is an elimination process and only you can do that.
If you try everything and still get no joy, restore your pc to an earlier point, uninstall the samsung drivers and re-install them etc etc.
I very much doubt its a software problem tho, looking at what you tried already, lots of people use hubs, if youre flashing roms and your connected to a hub then ya play a dangerous game and risk soft bricking your phone, most of the time odin wont recognise your phone through a hub, same if ya usb lead is too long, itll charge but no data. always connect it directly to the pc usb 2 port.

Ow, I think I used the wrong word. I meant to say port instead of hub.. Translation fail there. So that's not the problem, I've put the cable directly into the USB port.
I think you are right about the hardware problem. I'm just not sure where the problem is. I only have one cable, so I can't test that atm. But like I said, the connection problem does NOT occur on another computer. It keeps the device connected (as an unknown device though).
So it's weird: it looks like a SGS2 hardware problem, but on the same time it has a different problem on a different computer. It's really confusing...
Thanks for the quick reply by the way

Then please explain me how I could ever do that when there is no working ROM on my phone. I'm stuck on the 'restore with Kies' screen, like I told in my post (yes, still). And how it will ever work with ODIN? It won't...
Now not any computer is connecting with my sgs2. It just doesn't show anything (not even unknown device). I'm going to try to buy a new cable. Is it needed to buy a Samsung cable? Because it's harder to find than just a regular usb to micro usb cable (and more expensive ). This is my last hope. When it's not working, I need to send it to Samsung.

You need to replace your usb board within your phone. New part can be found on ebay for around $10. It's a really simple task replacing it. No soldering or anything.
It's been well documented on these boards.

First, i apologize if there is already a thread regarding this, but everything ive came across searching on google/xda has come to no avail.
i just got the i777, plugged it into my computer and nothing happens. on my phone it says "mtd connected" and charges.
ive turned on usb debugging, installed samsung kies, installed the drivers, tried the "dial *#7248#(or whatever it is), ive tried 3 different usb cables, all the usb ports on my laptop (brand new alienware), and also 2 other laptops. nothing works
my computer also makes the sound that its been connected. if i go into device manager it shows as Other devices > 7 CDC's with the yellow exclamation mark
if someone .could PLEASE help me it would be much obliged, all i want to do is start flashing again

Probably a bad usb connector on your phone. What rom are you currently on?
I was fearing this. Its all stock, not even rooted.
IF i have to get a new usb port, do i have to do any soldering?
When I had this problem I downloaded multiple different drivers and eventually found ones that worked . Try Google searching i777 usb drivers. I downloaded ones that worked from softpedia actually.

No soldering required. It's just a ribbon cable that connects to the main chip. Took me about an hour from start to finish, but i was being really careful.

He has said his computer recognizes the device, albeit it sees it as an unknown device. And it makes a sound when plugging it in. This tells me it's not a usb port problem but a driver problem. I have had this same problem. As I stated above. Even after installing kies it still didn't recognize it. I had to install the android sdk package, open the program and update, and then it still wouldn't recognize it. I had to download separate usb drivers for the phone as well. Who knows why, some computers or operating systems just have a harder time with the drivers. That's the problem in my opinion. Here's hoping it's not a usb port problem. Also this would prevent charging if it were a faulty usb port on the phone wouldn't it?

I wonder if the OP tried this on a computer with Windows XP. I've noticed Vista and 7 seem to have a hard time discovering/installing some usb devices. As for it not charging also..I think the pins inside the port are used separately for charging and connecting to pc.
My computer recognized my phone fine back when it was the Captivate, but it has a really hard time with my GS2. It often will say "invalid hardware id" or not show up at all. Usually it's fixed by swapping ports.
So I was just going to change ROMs, and I realized that my DNA won't connect to a PC over USB anymore. I always plug it in at work via USB to a laptop to charge, and it would normally open the autostart/autorun window, which I would always notice because I'll switch computers often. Last week the autostart dialog stopped opening, but I was distracted with work being busy and it just went to the back of my mind.
Until now.
I've checked all the normal trivial stuff... trying different cables, using different USB ports, and obviously different PCs. It also won't be detected by ADB. Yes, developer options are enabled, yes USB debugging is enabled. It sounds to me like its the port on the phone, so then I'm screwed, but I was just wondering if anyone knows any tricks I can try.
Are you running a custom rom? Go to settings>storage>storage settings>USB computer connection and make sure the connect as Media device (MTP) is checked. Same thing happened to me and some how this setting was unchecked

Have you found a solution for this? I am in the exact same situation with no solutions working for me. I tried PDAnet and many other things. The device is unrecognized by my computer completely not even showing up in the device manager. This likely is a hardware issue, but I'm rooted with no way to return to stock because I can't connect to my computer which makes me unable to use my warranty for repair. This is a really unfortunate pickle as I'm not sure if I can even do anything at this point. I have found online that people with a hardware issue with connecting to their computers also had the slow charge notification when charging either through the computer or the power adapter. Mine does not display slow charge which gives me some hope that it is somehow a driver issue. Do you get the slow charge notification at all?
EDIT: It's a hardware issue for me. Noticed my charger is sticking slightly more out than usual, and it just can't get the right connection

Hey guys, just figured I'd follow up. Sorry for the delay, XDA email notifications somehow ended up in my spam folder.
Anyway, for me it just turned out to be that all the cables I tried were bad. Pretty low odds, I'm actually surprised both my cable at home and the one at work were all bad. Sure enough I tried it with a coworker's cable and it worked fine.
