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.

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've looked everywhere and cant seem to find an answer, so i figured i'd start a new thread.
My captivate used to connect to my computer just fine, but there was another computer it would just NOT connect too! Well, after a few months, it stopped connecting to my home computer as well.
I have USB debugging on, the phone is rooted and everything. When I plug it in and mount the USB drives, i get drives J and K on my computer, one for the internal storage, and one for the SD card i have in the phone.
When double clicking any of those drives, it just sits there and reads forever without ever doing anything. I can use the SDK to run "adb devices" and it see's the phone, Odin One Click finds the phone but freezes on reading file line, or just fails all together.
Any ideas?
Try reinstalling the samsung usb drivers and restart your computer, that'd be my first step.

You have to be on the touch wiz home screen if you're trying to connect to Kies, otherwise turn on USB debugging and you should be good to go

SeenNotScene: I've uninstalled, rebooted, re-installed several times. I've been having this problem for a couple months now and i've tried everything i can think of. It doesnt work
bkhams: I dont even know what Kies is? I always have USB debugging turned on, and once connected i bring down the drop down menu and mount the USB so i can access my phones files as if they were another drive.
I had the same problem, and Samsung peeps told me I had to use the USB cable that came with the phone, low and behold they were right. Connected right away with the USB that came with the phone, could that be your problem?
I had the same problem in the past and it was actually a hardware problem with the Captivate and not anything with the computer. I ended up taking the phone in and they exchanged it for me.
I do not know if yours could be having the same problem, but that was my experience. Frustrating, to say the least.
Hmm... Could be the hardware i guess.. I know its not the cable though because i've only ever used the cable that came with it.
Have you tried connecting to the USB port directly off the motherboard? My connections were "sketchy" at best when using the ports of the top of the computer case. Once I connected directly off the MOBO, zero problems since.
Sloved!

Thank you for suggestions! My front USB connector is probably connected to some internal HUB, not going straight to the motherboard and wont work. Connecting directly to MB USB solve the problem. I am a little bit surprised... but whatever - M$ bull*hits. I spend couple of hours yesterday to find out whats going on. Thank you again!
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.
So this issue started a few days ago. Any time I plugged my phone in it would constantly connect and disconnect from the pc. I've tried multiple usb cables, ports, and the 3 PCs I have with the same result on each. Now when I plug it in, it is no longer being recognized by the PC, Odin, ADB, etc... It will charge but that is it.
I have a warranty replacement coming to me however I need to be able to get this one back to stock... Any suggestions?
Before anyone asks, NO it has never been wet, dropped, damaged in any way, set on fire, caught in a land slide, earthquake, what have you.. The phone itself functions perfectly fine. All drivers are up to date, none of my PCs configurations have changed. I have one I use specifically for app development and not even that one will see the phone.
I had the same problem. I used a different cable and it all worked better....now with that said it happened again so I flashed my phone back to stock and all was well.
Then went to flashing ROMS.

Really check out the micro usb cable. A bad cable will just about always allow a device to charge, but data transfer is another story. If you really have tried a few micro USB cables, then it the problem relies elsewhere. Try restarting both phone and PC, and if neither works, sounds like you have a busted port on the Skyrocket.
Thank you both for your responses. I am a PC technician so I followed my usual troubleshooting steps to figure this out. I narrowed it down to either all of my cables are bad (not a chance) or the phone is just f**ked (likely). Ah well ill have to try to use another way to force the stock firmware and recovery on here. Lol
HTC = Hate The Consumer
I use my old Nokia OEM USB cable. Connects with the right number of pins on the USB connection end. I'd check your USB cables for # of pins . Skyrocket uses 5 I believe. Also that there is sufficient power to your USB ports. Aka avoid front USB ports which could only be 4 pin....

When you plug the usb cable in, do you see the usb icon at the top left of your screen? I have to pull that window down to tell it to connect to pc, then confirm it again before mine connects. Mine doesn't auto connect on its own.
I see you've been a member for a few years so if its not connecting, that really sucks man. Hope you get it figured out.

Not running the AOKP ROM are you? The R3 build had an issue with this, and all AOKP will disable USB to PC if you enable 'fast charge' under ROM Control...
Good luck :S
According to what I've been reading you can try using the *#7284# code and setting the USB portion from PDA to MODEM and then back to PDA and it would kickstart the connection. No dice for me though. Ive been through 7 different USB cables already.. I am not about to go and buy one just to keep playing with it my other phones connect just fine using the same cables. No, I am running the latest Sky ICS
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?
Sent from my SAMSUNG-SGH-I997 using xda premium
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)
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 .
