Just got a brand new Samsung Galaxy SII T989 from T-Mobile this week, it really is a great phone, only I have a single problem.
The phone charges, it functions properly generally speaking (calls, texts, camera, wi-fi,etc...) but as soon as I connect it to my computer it freaks out.
It acts as if I were disconnecting and reconnecting the USB cable 2 times a second. I can hear the phone making the beeping sound it makes once you connect it to the USB every few seconds and in my computer (Which is running Windows 8 x64, just in case.) I can see the "Safely remove hardware symbol pop up and disappear a few times a second as well.
This is really frustrating... I love to take pictures and videos and edit them... I'd also love to copy some music over as well...
So far I've determined it can be the cable, bad drivers, or the phone itself, I just hope it's one of the first two.

Try re installing the correct drivers or switching the usb hub. If that does not work it's most likely the usb cable, swap it for a different one and you should be fine considering you bought the phone new.
Or you got a phone with a bad motherboard which would be crazy considering its new but that kinda sounds like the problem I had

Alright cool, but how does one find currently installed drivers when the device isn't plugged in?

Ok, does it get better or worse if you hold the cable with your finger when it is plugged in to the computer and phone and move it around a bit on the phone end? If so, I even got a Nexus 7 brand new from Google that the charge cable phone end was bad and would not make a good connect and I had to use a different cable and it works fine with my tablet.
If you use the same cable in your AC charger and on the computer then prolly not the cable.
It could be something in Win8 if it is trying to scan your USB port [like maybe a whacked anti-virus].
Have you tried a different USB port on your computer to see if maybe the one you were trying to use is bad itself?
If using a USB hub between your computer and the phone try removing the hub from the equation and connect directly to the computers USB port.

I am using a HUB on a Razer Keyboard that I've always used BUT now that you mention it my webcam had the same problem. It wouldn't work with the HUB on the keyboard. I'll try another USB slot (My computer's other USB slots aren't very accessible which is why I've hesitated to try another slot.)
I don't use anti-virus and yes, the cable works perfectly fine on the AC USB to Power adapter it brings.

I love you. It worked. It's the USB hub which doesn't allow much power to go through to the connected device. Thank yo so much.

Hi folks,
i purchased a new usb cable today. its retractable, called 'Sync "N" Charge'. it is essentially the same connections as the stock usb connection cable.
the problem is when i try to connect my (Imate Jam) to my PC(winXPpro) it either freezes my pc, or puts up this msg.
USB device not recognised, one of the usb devices has malfunctioned, click here(opens up systems properties).
It does charge the Jam. well atleast the orange charge indicator lights up(i havent checked for actual charge).
The device drivers for my Jam are fine seeing as it still works when i connect with my original cable.
my original cable works fine, even if i switch straight back to it after trying to connect with the new cable.
I think the cable may be wired incorrectly eg postive and neg prolly fine but the data pins are screwie some how, sound like a reasonable guess?
Is there something else that im not thinking of/dont know about that could be causing the problem?.
bleh just typed all that and answered my own question. the data pins in the new plug are a little bit shorter than the power plug. I use a silicone case on my Jam which stops the plug from pushing in all the way by like 0.25mm. took off the case and bingo problem fixed.
I hate when that happens.
Ok well i might as well say that its a nifty little piece of hardware now that i got it working.
Which leads me another question, the reason i got this new cable was to be able to leave it in my bag and pull it out when i wanted to use my Jam like a 1gb usb card(1gb sd card). the times when i wanted to do this would be at university.
is there a way to make a pc recognise the jam like a usb drive instead of a pocketpc upon connection? i wont beable to install activesync on university pc's.
Thanks

i searched around and i cant find the thread on this.
i was charging my phone through the USB port and it just randomly disconnected. i reconnected at it is recognized for a second then disconnects. the menu comes up on the screen and i see the notification at the top, but after about 2 seconds it just acts like i unplugged it
i have tried multiple USB ports, cables and different PC's and they all do the same thing now.
i installed HTC sync and rebooted the machine. i changed the power settings on the machine and made sure that the USB power management is disabled.
does any one have any idea whats going on?
Do you have a auto kill app such as taskiller ?
Sent from my PC36100 using XDA App
no... the phone was just hard reset. the issue was there prior to the hard reset
it does the same thing on my laptop and desktop
both are windows 7 x46 with HTC sync installed
could be your usb port on your handset OR/AND the usb cable's tip that you insert into the port could be loose/failing. wiggle the usb cord at the end where it connects to the phone GENTLY and see if its loose. should be s snug fit...
I have the same problem n started a few threads about it n havent gotten anywhere. My work computer has no problem seeing my phone but my personal computer will not, very very strange. Ill watch this thread n see if a solutions comes about.
seems like a very snug fit too me...
i should also mention that plugged in to the wall charger it has no problems
i have tried 3 different cables and 3 different computer and all USB ports on those computers, all the same issue
I didn't have this issue till now but suddenly same thing started happening to my phone..
I have plugged in my phone using USB with laptop and it shows me charging but after two minute it just discount it...
me and my buddy have the exact same issue here. what i do is, i unplug it a few times and on the 4th i keep it it. seems to be a bit more stable that way.
i don't think this is an issue with faulty usb ports on everyone's separate computers. (could be but i frelling doubt it) ive tried this in multiple windows machines (win7x64 and xp), and it happened on all of them. Only once did it happen on my work mac. i have not, however, tried a different micro usb > usb cable. i only used the htc one. we could have faulty cables. or it could be a phone issue itself, hardware wise whereas these are the only common denominators we have in this problem that i can see.
i lean towards faulty batch of cables. if you plug in the cable to your phone and computer, and wiggle the middle of the cable without touching the ends, it will disconnect.
what gets me is that there is no problem when it connects to the wall usb port. that is confusing. maybe the cable needs a more heavy flow of power to stay connected, which then leads me to believe that usb drives don't have enough juice to keep the thing going, or at least variable flows of power.
i know the phone has an "issue/feature" where it will stop charging the phone completely when it gets to 100% even if you leave it on the charger. maybe some sort of overcharging fail safe right? so what if there is something wonky going on with the phones usb port, or the phone cuts off the connection thinking your done using it?
its late, im speculating just throwing stuff out there.
I'm getting the same problem. Thing is, if it needed more power, why would it still work in a mac? I didnt have this problem until I went through a few different ROMS. So I dunno. I never had this problem before root. But I dont see any reason why it shouldnt fuction normally
Charging over USB works fine no matter the cable or the connection but it no longer will show up in Windows on any PC as a device. I tried flashing roms, changing cables, and doing the usb fix with Terminal listed in the sticky but it doesnt connect or will it know it's connected to a PC.
Can the port be broken so data no longer works but charging does?
its not the phone its the computer, try another computer

I have tried 3 which is why I wonder if my phone is broken, but it charges fine.
On all PCs the charge light comes on the phone with no problems but with all of them none of them detect a USB device being plugged in.,
Even in recovery if I do a USB-MS mount nothing happens.
Can the usb port break so that it charges with no issue but wont connect to a PC?

I think the solution to your problem can be found in this fix
The USB port on my Evo 4G will charge but won't show up as as a device on my laptop. If I hold the USB cable at an angle, though, it does show up. I think mine is busted, maybe that's the case for yours.

Do you think the cable is busted or the phone? I have tried multiple cables on multiple PCs and nothing happens.
So then it is possible for the phone to be unable to connect but still charge fine?

Have you tried mounting when in Recovery?
It really sounds like your cable is weird. The power lanes are on the edges for USB, meaning that the port on the phone is probably physically fine. The cable, however, is vulnerable to damage on any one of the four wires.
If nothing works, then perhaps something internal is busted. What do you need to transfer from your computer? Perhaps you can do it by connecting to your computer through WiFi for mounting the SD card and adb?
Its your USB port on you phone, theres 2 pins or smoething broken inside your phone thats causing the problem. I had the same problem on my Evo were it wouldnt connect as a storage device and would go into car dock mode. I took it to sprint and showed them the problem and they replaced my phone. As long as you dont have any physical damage such as the screen being cracked you should be fine and they should replace it free of cost.
Make sure that your cable is not one of those charge only, car charger type cables. Typical car charging cables don't transfer data.

Yeah, that's pretty much it. If I wiggle it just the right way the computer will see something but it will go away as fast as it shows up. Doubt Sprint will do anything as the phone is a few years old, I dropped the protection plan, and it's rooted to heck.
I'll just keep it running until this fall and upgrade when the new Nexus line comes out.
Hopefully.
So I have an I747 running stock 4.1.2 that was given to me by a friend. When I received it, I noticed I could not access it from any computer. I asked her if she had any trouble and she said no, that she always connected it to a computer and it was easily picked up. Before she gave me the phone, she factory wiped it. Since then, no computer can see it and no option appears in the drag-down menu. Using *#7284#, I set it to MTP and MTP+ADB with nothing changing. I have tried battery pulls, uninstalling/reinstalling drivers, Kies, etc., even changing cables (from cheap ones to the OEM Samsung and HTC ones). I've tried it on Ubuntu 12.10, 11.04, Windows 8, Windows 7, XP, and even Mountain Lion. No computers can see it.
Anyone have any ideas? I cannot even try to root or anything because no version of ODIN works. Yet, if I connect my S2 Skyrocket, all PCs read it, regardless of cable or OS.
I had this problem before and could not find a proper reason.
There *COULD* be a problem with your phones USB connecter. Some hardware could be damaged. This can be caused by incorrectly unplugging or plugging the device in, which can jostle the hardware and break it.
How long was the phone used for?
I hope you have a warranty :/.
Unfortunately, no, the phone does not have warranty. If the USB port were damaged, would it still charge fine? Because apart from no connectivity to a computer, the phone works fine and can see an SD card in it. Its internal storage is accessible through file managers, as well.
If it is damaged, would I be able to see the damage when opening it up? I would not hesitate to fix it if it is something I can re-solder back on or replace. I just do not want to get a replacement USB port if it is not the problem.
I had a very similar problem with my i747. If your phone charges when it's plugged in to the USB port of the computer, you might try this:
Make sure the Samsung drivers are installed. Power off your phone. Power on the phone in Download mode. (Volume Down + Home + Power) Press Volume Up to continue. Once it's in Download mode, plug it into your computer. Windows should now discover it and load the driver. Once this is complete, unplug the phone from the computer, and pull the battery out of the phone to get out of Download mode. Replace the battery, and power on the phone like normal. It should connect to the computer properly.
I found this on the Verizon S3 forums over on Android Central. Worked for me after a lot of other things didn't.
Best of luck!

I have never been "in" the USB port area when taking apart my i747, I would assume it would be visible...but you should try the suggestion of USB drivers from the poster above

In some cases, yes. Charging operation only needs the positive and negative 5 volt pins on the usb bus. In order to transfer data ( and be recognized by the host OS) you must also have connection across the two data pins. It is possible that one of the data pins on the phone's connector OR either end of the micro usb is bent, broken, or otherwise not making connection. Also i have about a hundred (more like 10 but you get the point) micro usb cables laying around and some will ONLY charge. I can't give you a scientific explanation why other than the phone just doesn't like some of them so trying a different micro usb could be the key.

Like you said, I think that sometimes a phone not liking a cable is the truth. What sucks is I never had this problem with my s2 skyrocket on any cable. I may have to send it in for repair if anything. I upgraded to 4.3 last night and still the same so I feel it's definitely a hardware problem.

Thanks for all the suggestions, guys.
Hello,
When plugging my HTC One M8 into my laptop, about every 30 seconds there is the sound of a USB being plugged out and then plugged back in, and then the typical windows 8 "what do you want to do with this device" notification. I dont think its a laptop problem because my USB memory sticks etc work completely fine. I've tried with all the USB ports, both 2.0 and 3.0.
Any ideas as to what to do to troubleshoot?
Thank you.

I have tried with the cable that came with the M8, and also the cable that came with my old Desire Z
1. Uninstall the drivers for HTC m8 from device manager , accept to delete all drivers and restart you laptop. After restart reconnect your phone and fresh install your phone. Use your original cable.
Sounds like bad cable, bad USB port on pc, or port on device is damaged. Rule out the first 2 first. Try another pc too. If not, probably your device port unfortunately.
I've seen a couple other reports of this happening on Win 8 (8.1 specifically?); and bad port or cable did not seem to be the cause. Don't know if a solution was ever found.
I've had this problem with some cables. An old Treo Pro cable I have does this, as well as a generic 3rd party cable too. The genuine HTC cable works fine as does a 3rd party flat cable I have. I always forget about it and spend 2 hours trying to figure out why the blasted thing kept disconnecting, then I remember and use my trusty OEM cable and all is well...
