My samsung galaxy does not recognize that it's connected through a USB cable connected to my computer, and thinks it connected directly to the wall plug.
Is there any way to force-connect to the computer or something.
I don't know if it's the cable or the phone. I hope it's the cable, because it's a new cable, and this had never happened before. But then again, this should not happen. Right?
untick usb debugging in settings/applications/development
still nothing.
Have you installed kies or samsung usb drivers for s2 on your pc ???

Do you see some errors in Device manager?
If yes, try to update every driver marked as error.
Try to update windows. It's very important to install Samsung driver from windows updates. This is how do i resolved my problem.
Good luck!
I was just having the same problem myself, and found a possible solution. Make sure you're using the cable that comes with the phone. Other cables (such as for HTC phones) will charge the phone, but won't allow data transfer.

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.

I cannot seem to get the phone to identify on the PC with anything but the Samsung USB cable.
The problem is... I think I already lost it.
I have 4 basically new microUSB cables from various sources and none of them will do anything but charge.
WTheck has samsung done?
Did you try changing the mode on your phone from Change Only to the Hard Drive one once you connect it?
Try a different USB port. This phone works on every USB cable I have in my possession.
i find mine charges really slow unless i use the samsung one:/

Because the phone only charges it does not adapt a mode and therefore wont' let me change it.
edit: fixed it. Problem was I used a program to try and turn on UMS mode and it wasn't working. Wouldn't do any other mode until I turned it back.
But I still have had problems usb cables. The one with my Nook for example wont work at all and it worked with both my nook and my atrix.
S3 wont even recognize on a mac.
surprize me with something amazing android your boring me.
Mine works with the Sensation cable on my main PC, my G2X cable on my laptop and with my Lumia cable in my gym (charger). It also works fine at work with a generic cable (on a PC). Either your phone or your cable is defective.
EDIT: make sure your drivers are up to date on your PC.
Mine works fine with BlackBerry/HTC/HP cables.
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.
Hi.
I have an Xperia X10 that I gave to my husband. He's good with computers etc.. and he went ahead and unlocked and rooted this phone. It's working awesome - EXCEPT - when you plug it into the computer via USB the computer will NOT recognize it. It says exactly, " "USB Device Not Recognized
One of the USB devices attached to this computer has malfunctions, and Windows does not recognize it. For assistance in solving this problem, click this message"".
Here is a bit of background info:
Before my husband rooted the phone etc. the micro usb port on the phone wasn't working properly - it was loose and you would have to really wiggle it, bend it etc.. to make the debug engage. He did get it to flash/root/unlock/install custom rom successfully ( he installed doomkernel 2.6.29-modFXP-DooMKernel-v06) all while the phones usb wasn't working ideally. At this point he was trying out some settings and branded it as a X10i Generic. (This phone WAS a Rogers phone and we are in Canada). He then wanted to change the branding since x10i wasn't working too great. At this point the USB port on the phone wouldn't engage into debug or charge anymore so we took it to a repair place and they soldered the usb port back - they told us this was common (them coming loose). After they soldered it they said it wouldn't go into debug and that it was because (probably) of the firmware my husband put on but didn't really know.
From that day on this phone has never connected to the computer successfully - the computer won't even recognize it as a memory card - as soon as you plug it in it tries to install drivers and then the computer says exactly this::
"USB Device Not Recognized
One of the USB devices attached to this computer has malfunctions, and Windows does not recognize it. For assistance in solving this problem, click this message"
Our computer is running Windows 7 (64bit) - and the phone use to work fine.
We have tried using SDK tool, installing drivers manually when the phone is plugged in, but the computer will just say that it is already up to date, and it names the phone ' UNKNOWN DEVICE" and has the exclamation box next to it indicating it's malfunctioned. Sony software (PC Comp. etc) also will not detect the phone.
Have been trying to get this working for about 2 months now. 2 months of reading, google searches, more reading, trying idea after idea, and it doesn't work.
Has this happened to anyone else? Can someone help out here? Is this a firmware/software problem (maybe because it's been branded as a x10i)? Or could this all be a matter of the USB port being improperly fixed?
Facing same USB malfunctioned issue
I am facing the same issue since quite long since i have rooted my Samsung Galaxy 2 SGH T-989. My phone gets connected properly but when i try to transfer any of the files from computer to my phone. It gets disconnected automatically after copying the stuff till 5% to 10% and shows ''USB device has malfunctioned".
I am also trying to search and rectify this issue, but till now i have found nothing. Please let me know if you come across of kind of solution for it.
Im sometimes facing the that unrecognized USB but, everthing working.

I faced the exact same problem with my x10 mini. It wouldn't charge properly nor connect to my PC. I would have to wiggle the micro USB port and cable to get it working, which actually got me wondering if the problem was really the USB port. After I've bought a male-male USB to micro USB cable everything worked fine. Same thing happened with a brand new x10. I tried to use the USB cable I bought instead of the original one which came with the phone and you wouldn't guess, everything works fine.
So try to connect it with another USB - micro USB cable.

We have already tried connecting it to all of the (10) usb ports on our computer and we have tried NUMEROUS cables ( between my husband and I we have probably 8 cables, and have tired them all)
For some reason my phone will not connect to my computer through my USB. I have tried everything and my debugging is on as well. yet still it does not connect. It charges the battery very slowly with USB, much faster with wireless charging. Adaptive fast charging does not work either.
No contact even with Odin via download mode. Have all the drivers and have tried different USB cords.
When you do not make contact with Odin, is it the hardware that is broken?
Have tried different roms in my phone.

I think it might be the USB port on the computer. I know my computer often has difficulty keeping a connection, even when I use a different cord.

Buy new cable because original samsung are defective. They work ok when charging, but usb data transfer is a hell. With new cable it works perfect but I am so disappointed with samsung. We have 2 s6 edge (32 and 64gb versions) in house with same cable issue ( I previously owned 3 S tabs and galaxy s, s2, s3 mini, s4, s5 mini and now s6 edge)...This is really really disappointing from Samsung. After S2 they started making lousy mobiles (s4 was ok)........Will not buy Samsung again!!!
