When I plug my USB cable into my computer and then into my phone the phone does not recognize the computer and vice versa. It will charge, but that is it. A few weeks ago I tried an AOKP rom which has "fast charge" I set this setting to be on to test it out and then turned it off. Ever since then I have not been able to transfer files with the cable plugged in, so I used AirDroid to wirelessly do it. I remember something in the warning about it, but I thought when you format/wipe and flash a new rom it corrects the issue. I have flashed a completely new rom since then and still nothing. Any help would be nice, thanks.
Try going back to stock through Odin or heimdal

How are you supposed to Odin/heimdall, if it doesn't connect even during download mode?

Lol didn't think of that...when I had my infuse I had the same problem with the stock USB cable...after a while data transfer stopped and it became a charge only cable...I would use my dads cable that worked perfect for data transfer...
So try a different USB cord or try a different USB port...

You can try this too
Hi, I faced this issue few times and tried several options like change cable/port/computer and worked.
One thing Recently i noticed when all of the above failed in my case is :- 1 Development->Uncheck the USB debug mode, 2. Check Mass Storage in USB connection setting. ( you need to unplug usb cable while doing it)
Now try connecting and give few minutes. If you can see the USB mass storage notification you are good to go. Go back and change the Debug mode as Checked.
It worked for me couple of times hope it may work for you too.

Sounds like the dreaded USB port failure. Many Infuse users have gone through this as its a known issue. I returned mine and got a replacement via warranty.

Hey There,
We had the same issue with many units and solved all by doing the following:
-Flashing the unit back to stock
-Performing a factory data reset after flashing(This is a must)
Note: Even though your device will not connect to the computer in PDA mode you should still be able to connect in download mode so it can be flashed with ODIN.(Unless if it's hardware related)

After I installed Froyo on my Captivate, USB is not working. When I connect it to my Win7/64 and Vista/32, I get the "USB device not recognized" on the computers, regardless if I am in USB debugging or not. I reinstalled the Kies s/w in the hopes that the drivers would then recognize the Captivate, but that doesn't work. So obviously USB tethering and Mass Storage are not working. Has anyone else had this problem and how can it be fixed? Thx in advance!
Have you tried mounting the phone in debugging mode? This has always worked for making the drives accessible.
Sent from my SAMSUNG-SGH-I897 using XDA App
Yep, I stated above that I tried with debugging on and off, and it didn't matter. Usually the phone would mount differently with it on or off, but now it's just not recognized. Very strange...
have you tried using a different usb port? i was having the same problem and got it to work when using a different usb slot
I'm having the same problem. It also often decides not to recognize when I've plugged it in to charge. Used 2 different usb cables, 3 different usb ports on my tower, usb ports on 2 different laptops, and plugged in using the stock usb cable/charger combo. I'd like to flash a new rom, but obviously that's not an option for me right now. It double sucks, cuz I just did a factory reset. I also tried the above suggestions to no avail
EDIT: When I unplug the phone while charging (once I finally get it to recognize that it's hooked up and should be charging), it still shows the battery icon as being charged
same problem. sort of getting mad. i have tried lots of stuff. un install re install drivers a couple times now. both pre select and post select usb modes on the phone well any way lots of stuff. all the usb plugs, tryed putting the plug in the pooter first then the phone on all ports. phone with sim in/out all ports and memory card in/out all ports i reall want to try darky's rom. as sweet as xxxbunker.com is with flash on the phone, i would trade it back for 2.1 so i can use my headphone jack for speaker phone again. please some one help
#edit: my wifes phone still works fine on mounting with the vista pooter. she still has 2.1#
I have been searching for about a week now and still can't figure this problem out. I bought this phone used about a month ago and I haven't tried to connect it to my pc until just recently. I am wanting to root and unlock my phone but I can't connect to pc using usb cord although it will charge it.
I am on GB 2.3.6 vuvkj6, stock.
I have tried 4 different usb cords, 4 different pc/laptops and all usb ports. I have also installed and uninstalled several usb drivers with no luck.
My phone can only get into download mode using a jig. Even in download mode, I can't connect to pc. I have tried using Heimdall, Odin, and kies but it just does not connect.
If I can use a jig to get it into dl mode, does that mean the phones usb port is fine?
I just want to be able to connect with pc. Is it possible to flash using my sdcard? I am thinking maybe the phone is missing something to pick up the usb signal or something.
I am lost, any help would be appreciated.
Maybe, I think it's a phone issue.
Do you still have a warranty?
I bought this phone used, so no warranty. If the jig works, does that mean the usb port is ok?
Does the phone charge when plugged in? Have you tried to go ahead and flash even though it says not recognized?
ligitalipeople
Yes the phone does charge when plugged in. I can't flash using Heimdall or Odin. Any other way of flashing?
I have also put the phone into debug mode with no luck.
Have you done a factory reset?
Yes, I have done a factory reset.
FINALLY! I got it to work.
Can you post back here and tell us what you did to get it working in case someone else has the issue?
Thanks and glad you got it going!
I am not sure what made it work for me. But what I did was "clear memory" on ram. I don't remember how I got onto that screen but I clicked on ram and clear memory.
I then pushed the usb into the pc a few times really fast until pc showed somethnig other than "usb device not recognized". Pc then started to show device connected.
if you are using windows i have found that sometimes the usb ports u used for the phone get stuck to the driver that was there in the first place. So what I do to fix this is go into device manager from the control panel and then uninstall the drivers for the specific port that I am trying to use. While keeping my phone unplugged from the computer I then reinstall the samsung drivers, restart my computer and then try to plug my phone in. 90% of the time that has been what works for me.
Ok, I figured out the problem. It has nothing to do with the drivers or clearing ram memory. My problem is the actual micro usb connection. If is a little loose from side to side and when I push it to one side, it connects no problem.
That is the exact same thing that happened to my wife's phone... luckily it was still under warranty...

My phone is out of warranty. At least now I know the problem. It was extremely frustrating trying to figure it out.
This has been happening ever since I flashed my phone a second time. First time was from stock to MIUI (USB worked with MIUI), but when I flashed it to I think GB it just stopped working. Whenever I plug it into my computer, all it does is charge my phone... I tried multiple USB ports, none of them work, all of them just charge my phone... Help?
EDIT:
I just restored my phone, I'm on Firmware 2.3.6; Build#: GINGERBREAD.UCKJ4
Try changing cable?

same thing pretty much, but with a stock rom.
about a week ago my phone would not charge from an outlet very well, it was like i didnt even have it plugged in, it's gotten worse since then...
when i was able to get it to charge from a wall outlet it would go into usb mode, and that was if i was lucky.
now it wont even charge from a wall outlet and i have to charge it from my computer.
i would try to update my phone to the new 2.3 version but my computer wont recognize my phone, i keep getting an error message saying "One of the usb devices attached to this computer has malfunctioned, and windows does not recognize it."
i've tried to put it in kies mode and debugging mode and the rest of the modes allowed but still nothing.
i did a factory reset and it still does the same thing(and i lost EVERTHING on my phone but my contacts)
any ideas??

I have the exact same problem. I have tried installing Kiesmini, the samsung usb drivers directly and tried on mac and pc with different cables.
The cables function normally with blackberry's and samsung galaxy ace but the infuse refuses is not recognized by the pc. also the phone does not recognize that it is connected which usually shows a prompt for USB.
Any help will be greatly appreciated.
P.S. I am on 2.2.1 stock Froyo and I am unable to root because of not having connectivity to usb through the computer for Superoneclick to recognize. Also, i tried z4root several times to no avail.

So my girlfriends little brother gave me his skyrocket. He asked me to backup his pics, which I did with no problem. I then did a factory reset. After that, my computer does not recognize the phone! I've tried different cables, different computers. My girlfriend has the exact same phone, connects right away.
I even flashed it with a different rom and put ICS on it. No luck! I then proceeded to take it to a phone repair place, thinking it might be the actual usb port. They said they checked out the port, and it look fine. All solder joints were good, no bent pins.
The weird thing is, is that it connects on an average of 1/20 times! It charges perfectly too. The phone doesn't go in and out of charge mode if i wiggle the cable either. I'm kind of confused! Is there a file on the phone that tells the computer what it is when connected? If so, can I manually replace that file? WHAT DO I DO!
When you goto recovery mode can you goto mounts and say mount usb? and does the pc recognize it then?

Kind of. We had trouble with it when flashing it. I personally didn't flash it. I watched my friend do it
Sent from my SAMSUNG-SGH-I727 using XDA
You could try installing the drivers again..
You mean on the computer? I did that. No luck. It does connect more often though WITH the drivers.
I had some problems with USB connectivity too. Using the cable that the Skyrocket came with solved my issues.
Have you tried any combination of restarting and reinstalling the drivers?
Swyped from my Nook Tablet, running CM7.
Yes. I've tried multiple cables including the stock cable. Installing drivers, restarting both devices. I have definitely ruled out the cable, the PC ( PC's actually), and the physical USB port.

I had similar issues, messed with phone for a bit and came up with this
System settings>more>USB utilites
Now I got a screen that says USB mass storage with a button that says Connect storage to PC. Tap Button.
A window will pop up asking to Turn off USB debugging (if on) Tap OK
Connect USB cable to storage (plug USB cord into PC).
You should now be at the USB Mass Storage screen, Tap button at bottom (Turn on USB storage)
I found this to be the way to turn on Mass Storage since I flashed ICS, I believe. Hope this helps you, it took me a little while to figure out.

Of course, that's how it's always been except in a slightly different location on ICS

I took it to a repair shop. They said the port was perfectly fine!

how exactly did the repair shop test it?
try plugging it into another usb port on the same computer or try using a different computer. It could be the usb port on the PC itself.

That's the first thing he tried, it's in the OP
yeah i've tried everything! The repair shop determined that the port was good by examining it under a scope and they also said they tried re-flowing the solder joints. They said they wanted to stay away from replacing the usb port because it was very difficult to replace, not to mention they didn't warranty the job!
Someone has to know the answer to this!

if its still under warranty replace it, thats all u can do. No one else in this forum besides u can physically touch the phone, so if you've tried all suggestions thats all thats left
i have the same problem but mine is little different, when i power off the phone it keeps on going to download mode, i keep on restarting it and it goes back to download mode, i flash stock rom and it does the same, i flash ics rom and it keeps on doing the same can anyone help?
So I flashed my infuse from Froyo to GB to ICS and then to JB...but ironically the same day that i flashed to JB, my download mode stopped working.
Ever since I flashed to JB (CM10 and slimbean so far) My computer says "USB device is not recognized or has malfunctioned" and I cannot put the phone into download mode via 2 buttons and usb cable. When I plug the phone in it just turns on and starts charging and the computer wants nothing to do with it.
I know the USB port works because it charges without a problem. I have also tried 2 other windows 7 PCs, and my macbook. Can't get it into DL mode or to mass storage.
Any ideas?

Just cause it charges doesn't mean it works...that just means the power part works...power and data transfer are two desperate things...I've had cords in the past that after a while stopped working as data cables and became strictly charge only cables...
So, have you tried a different data cord? Its likely the data transfer cables got damaged due to normal wear and tear (these cords arent made to last...)

Try a different cable, just do it. Denial is not good. I had same problem then got a different , different cable and it worked. As i tried three cables. I do believe one did work to get mass storage but it didn't work to flash my xperia x10, that's what bugged me.don't really remember as i have bricked these phones so may times experimentation ya know, it is hard for me to remember .
as i was flashing my infuse at the same time i used the data cable that does work with the infuse and my other cable wasn't working it wouldn't recognize and ahhh went through my head so after infuse got done i switched cables and vola it worked.
If not then reinstall drivers reboot pc and get a data cable that is really a data cable .
