Just a quick question- I have a Captivate that will charge when plugged in via USB but there is no data connection. The phone doesnt recognize that its plugged in to a computer, and therefore despite being able to boot into download and recovery mode, I cannot use ODIN to do anything. Clockwork wont work either due being on 2.2.
Ive read some other threads where most concluded it is more or less a hardware failure. Im coming to that conclusion myself, but wanted to check with you guys first. The audio jack did the same thing for a couple days-- it wouldn't work when plugged in. It did come back on its own, though Im not sure why.
Im running Cognition 2.2beta3, and cannot flash back to a stock rom nor to any other rom due to the lack of being able to use ODIN.
Is there any other way to flash back without ODIN? Also, if this is indeed a hardware failure- how can I go about getting it fixed? I traded for it on craigslist for an iPhone 4 so I didnt get it direct from AT&T. It did work for the first couple months.
Thanks in advance for your help!
Do you have USB debugging enabled (Settings-Applications-Development)?
If so, you won't get the connection choice screen when you plug in your USB. You can either disconnect USB debugging to get the choice screen, or leave USB debugging enabled and click on the "Select to copy files" choice in notifications.
I have tried with USB debugging on and off, and in various USB modes. None work, as the Captivate doesnt even acknowledge theres a data connection that has been made.
It worked in the past in all modes... debugging with the option to mount the drive, mass storage, Kies, and the media mode. No dice at the moment. Tried a hard reset today... nothing.
Looks like it could be a hardware issue-- just weird as the audio jack had the same issue and seemed to (randomly) resolve itself. Thanks for the suggestion! Any other ideas?

I had the exact same issue as you few days ago. One forum member recommended to me to uninstall the Samsung USB driver and reinstalling it again. It worked as soon as I did this. You should give it a try.
I had a similar issue when performing a master clear and flashing JI6. I am on windows 7, and I noticed that a different driver is needed to use Odin in download mode. I had been sideloading apps as well as transferring files with the stock driver from samsung, but my computer still wouldnt recognize the phone when in download mode. The solution was quite simple, when entering download mode my computer gave me the "driver not found" messege. I just let Windows Update find the right one for me (not sure if its generic or not) and everything worked fine after that. Hope this was relevant to your issue.
And I guess you can't do the phone off, open Odin, plug in USB with vol up/down pressed, right?
Not sure if this will help, but I bought a second USB cable to carry in my laptop case. If I use it I can charge the phone but cannot connect it to a PC. If I use the one that came with the phone it works fine.
I have actually tried some other cables and they have issues too. They all have a larger cable housing towards the end that plugs into the phone, where the one that comes with the phone is slimmer.
A friend at work as a Fascinate and he has the same issue, we suspect that the increased size is keeping the usb from connecting all the way in the phone.
Ive tried different computers and different cables, as well as different drivers. Ive used 64bit systems and 32bit systems... XP and Vista.
The phone itself goes into download mode, though I have to go through the terminal and use 'reboot download'. I cant use command line on the computer as it doesnt find the device... the phone never is identified to it. It just charges.
Is there any way to perform the commands that ODIN does without actually using ODIN? If nothing else, Id like to flash back to JF6 and be able to use the OTA updates. At this point, Im stuck till clockwordmod works with 2.2.
I experienced the same thing. My Captivate would charge, but it couldn't connect to any of three computers (WinXP w/drivers, Mac OS X, and Linux) with either of two micro usb cables I had. I would always get a USB error in some form.
I was on cog 2.1, and was able to roll back to the JH7 OTA update without ODIN. Afterward I brought it to an ATT Tech Center and convinced them it was a hardware failure.
I got a warranty replacement, and it didn't work either.
It turned out to be bad micro usb cables. One was the original Samsung cable, but it was loose, there was plenty of play and wiggle in the sockets of both phones.
The best micro usb cable I've found is from a Kindle. It has a a larger plastic base than the stock from Samsung, but critically it has a longer connector. There's a solid click when connected and absolutely no play or wiggle possible. It works every time.
I don't know if you can restore from 2.2 to JH7 without ODIN. Now that we have 2e Recovery on Froyo (in Cog 2.2 BETA6), could you use Clockwork Mod (Rom Manager) to flash designgear's JH7 OTA ROM?
Try some alternate micro USB cables, you might be surprised!
Im having the same issue, was there any resolution to this from the OP??
I suspect hardware also, and Ive got another Micro USB on order from Amazon and will prob buy one from a store tomorrow also.
the stock cable is horrible, I bought a nice charger the other day and it has a nice click and stay, and since I plugged it in to the new charger it no longer shows up on any computer with the stock cable. Im wondering if the new charger with a tad larger connector spread the connectors just a tad too far for the stock cord.
I tried everything as well, I hard rebooted, put into recovery mode and even deleted all my user data to try and see if there was some software that was blinding the computer to the connection... no luck
Ill let you know what I find.
Same issue here. Has anyone had any luck with a new usb cable? Luckily, I can transfer files from my computer via bluetooth for now, but it takes forever!
I've been having USB driver issues for a while now with my captivate (On serendipity 4.2 right now, finally decided to try to get to the root of this issue and update); I've used the SAMSUNG_USB_Driver_for_Mobile_Phones_x86.exe (and I am on 32 bit Windows XP SP3), and have always received a "USB Device has malfunctioned" message whenever I have tried to plug my Captivate in.
My computer has 2 USB Ports; one of them has a USB 1.0 hub plugged in (which has a keyboard & Plantronics Microphone plugged in as well) and the other has a Logitech mouse. I've tried both of the main USB ports, as well as the hub. The hub's been plugged in when installing and uninstalling (I'm trying to give as many details as possible in the hopes that one of these might trigger a red flag).
Anybody know what the problem might be? Maybe I've been uninstalling the drivers incorrectly? (I've done it through device manager & restarting the computer before reinstalling)
EDIT: No Kies on this computer, has never been installed; I have been mounting the device via the notifications menu but it still gives me a malfunction error.
Hmmm.. You've done everything that I would try as well...
At this stage I can't really say it's anything specific... Have you tried it on any other computers by any chance? Or got it working before?

Should mention that I got it working by turning on USB Debugging mode on after installing the drivers, then plugging the device in, and after that it began to function as normally.
So is it working now or not? Sorry, the latest post is a bit confusing...
I think that's a known issue. I usually can not get my computer to recognize my captivate without enabling debugging

Yes, it is working 100% as it should be.
Does anyone else have this problem? When I connect my phone to either my laptop (winXP) or my desktop (win7x64) I periodically - constantly, really - get this message:
"One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message."
When I click the message, it identifies my phone as a Generic USB Hub (4 ports) with the first child being a USB Mass Storage Device, the second being the problematic "Unknown Device" and the last two are "Unused Port"s.
This happens whether the phone is in charge-only or mass storage mode. I tried installing the autoplay drivers and that didn't help, so I uninstalled them. No hubs are involved - I've always plugged straight into the tower or laptop. I've also tried two different quality (first party Motorola) cables.
Mass storage mode works fine despite the error - I can access the Internal storage as well as the SD card. Is this a problem with my phone, or am I missing some software on the Windows side?

Thanks for the suggestion major. I tried those drivers with no luck - the message still pops up frequently in both charge and mass storage modes.

Odd... I had issues with the original drivers, but once installed, I never had another prompt again.
edit: I had it one more time, but it found them and installed them
that's very interesting. i also use 2 machines--one with xp and one with win7. my usb connection worked flawlessly on both. fyi...my connection default is mass storage, and i've actually never tried the other options. i wonder why the difference? did you make any changes? are you rooted? i am not.

Hi gr33nT,
Thanks for responding. I'm 100% stock at the moment, not rooted or anything (though it will be soon ) Sometimes I use charge only if I have it connected to my laptop at work but I still want to listen to music from the SD card. I may see if I can get Verizon to swap out the phone, the message pops up all the time and it's getting annoying...
A quick follow-up on this one: I tried the stock LG cable on my win7 machine (I had been using moto cables). I installed BOTH the bootstrap drivers as well as the LG drivers from the web - still happening. I rooted with these drivers via S1C so I know the drivers are good. If nobody else has run into this, something is probably wonky with my phone, so I'm probably going to exchange it.
For mine, every time I connect, it asks me if I want to install bootstrap. Even though, they have already been installed cuz I am rooted.
I've had the same issue both as stock, and rooted and in every configuration with the phone and PC you can think of. I've downloaded the drivers and installed them from both the phone and web site all to no avail. This is really getting annoying.
I hope someone has a fix for this.

Hmm...that is troubling. I'm still having the issue running the stock rom and rooted, now. When I get time I'm going to drop by the Verizon store and hopefully they'll replace the phone - I suggest you try the same, as I doubt it's the computers we're using. My win7 box and winXP work laptop could hardly be more different!
I doubt a replacement will fix anything, I experience the same thing as majorpay. Drivers worked for a while and then it started asking for it again. This also causes issues when using usb tether as its connecting and disconnecting. The issue is not present when used as a mass storage device.

Hi bwhxeon,
The issue (USB device not recognized - it sounds like you're referring to the autoplay driver installation) happens for me in mass storage mode also. I believe it has to be the phone as I've never had this problem on any of my PCs with my OG Droid or any other USB device. With this phone, I have the problem on all of my PCs.
I had the same problem. The error popups seemed random at first. I noticed if I enabled/disabled the WIFI on the device while it was connected, I could make the error popup.
I ended up getting a new replacement device when I also noticed the 4G Hotspot wasn't working either even after a factory restore. There was definitely a hardware issue with the phone.
USB Unknown Device
same issue here.. when using ADB though I have to set to Internet Connection then it goes away for a while until I want mass storage or just charge from USB again, then re-appears.
LG is not like most other phones as in usb debugging only works in internet connection mode where others go into it as soon as you plug it in.
Just kind of scanned this thread but have you tried a different USB cable? I was having a problem with mine only wanting to charge with the stock so I grabbed another cable and it has worked right ever since
Same issue, two different pcs, with two different cables. Bootstrap does not load anymore so I am using the drivers from the links, both sets of Lg verizon drivers

Hey all,
Recently I have gotten need to RUU my phone. It has a custom hboot 1.56, S-OFF, and is running CM11. My problem is that my computer will not recognize my phone whatsoever. In fact, it doesn't even show up in Device Manager OR the "Safely Remove Hardware" icon in the task bar. USB Debugging is enabled on my phone, and I am using the adb binary from the RUU package.
What's strange is that Windows doesn't even bring up a message to try and install drivers or anything... it acts as if nothing was ever plugged in. On my phone, nothing happens except it begins charging. Not even a USB storage popup or anything.
I'm not really in a location right now where I can test out another computer to try that, nor do I have a spare cable handy at the moment. Has anyone ever had the problem I've having, and if so, what was causing the problem/fixed the problem? I'm thinking it's the cable, but I'm not really sure since it CAN charge the phone.
Thoughts?

It's probably the cable. I had to install CM on a Tab 2 for my friend and his cable didn't work, only charged, so I had to get another cable, which worked fine.

Hello fellas,
I have a problem with my brand new T813 running the latest official firmware available (Android 7).
Massive storage is not working, my computer running Windows 10 with updated samsung drivers has failed to detect it. The device charges, but I am unable to modify the usb options, regardless the choice MTP always remain.
I have tried with three different cables, all of them work fine with my S7, the computer never detects the device, eventhough it's charging. This means it is not a problem with the device's micro usb port. I have the latest drivers, and I have also tried with all usb ports. None of them seemed to do the trick.
The computer has faulty usb 3 drivers, ever since I have installed Windows 10, the speed is not what used to be with the previous configuration. I have the same drivers, I don't understand what's wrong.
Any help would be appreciated, I have tried most solutions mentioned on this community and they didn't work. I can't flash the device because it is never detected. The problem still persists after a restablishment via the menu.
Download mode shows
QUALCOMM SECURE BOOT: ENABLE (CSB)

[UPDATE] 06/08 11 AM
Left the device at SAMSUNG ARGENTINA repair shop. Also had to pay 300 pesos (around 20 dollars) as a diagnostic fee, they told me that if I accept the repair cost later on, they would discount the 300 pesos I have paid out of the total price. And if I don't, they will keep the money.
Will update again when Samsung calls me in a couple of days. Maybe this monday, I hope so.
[UPDATE] 06/08 15 PM
I have just received an email from BGH, which is the SAMSUNG ARGENTINA official partner for repairs. They told me that the problem is a FAILURE on the SUB board.
http://www.ebay.com/itm/Micro-USB-C...g-Galaxy-Tab-S2-9-7-034-SM-T813-/322414846816
The good thing, is not that expensive. The bad thing, this tablet hasn't arrived officially to Argentina, and since it has been bough in Chile, the guys at SAMSUNG ARGENTINA had to request an international order replacement, which I have been told it could take some time. But they will eventually get the piece.
Will update again.

Thanks for replying, please refer to first screenshot. No Mass Storage option appears after connecting device. MTP option seems to be forced, i am unable to change it.
The tablet is brand new, but the guy who sold it to me said that it has always been working. He even told me that it has been barely used, and that the device is recognized when connected to an usb audio system. It has been upgraded to 7.0.1 a couple of days ago, maybe that's the problem.
I have just tried with a macbook air and it didn't detect it either, it is only charging. The same computer has detected my S7.

When the problem appears with different USB cables and in different computers, as in your case, you have to look into the possibility that it may be a hardware issue.
I hope I'm wrong about this, but it sounds like the DATA+ or DATA- pin is damaged in your micro usb socket (pins 2 and 3, see http://pinouts.ru/PortableDevices/micro_usb_pinout.shtml)

Yes, I'm afraid it could be a hardware problem. But that would also mean the guy who sold it to me is lying. I have to say it, the device looks like it has been treated with care. However, i have noticed the plastic has worn out a little near the usb port, those black marks could indicate not so much care when plugging or unplugging the cable.
I hope we are both wrong about this. Tomorrow i will know. Fixing this is a pain in the ass, right?

¡Che! Replacing the microusb receptacle would not only be a pain the ass, but if you make a tiny mistake while soldering or desoldering you can end up with a bricked tablet.
Anyway, let me know what you find out tomorrow, good luck boludo.
