[Q] USB Connection? - Captivate Q&A, Help & Troubleshooting

I am on CDE-AOSPb3.1 on JI6 Froyo.
I am having a USB device not recognised error on my Win7HP x64 machine, and it is not allowing me to connect my SD cards to the computer. This has actually culminated in a BSOD on my computer, presumably because something is wrong with my phone and the USB connection was messed with. The BSOD, however, was isolated, and has not happened again; a full reboot of the phone has not helped this issue.
Any ideas? Or is this a Development question? I have run this ROM since its inception, and have never had a problem until now. It does still charge on USB, however.

You could always try going back to your previous ROM that was able to be recognized by your desktop. If it does recognize it, it might be a ROM problem.

A Nandroid restore didn't work, because the actual root of the problem was a bad micro-USB cable. Borrowed a colleague's and it's all good now. Time to buy another...

[Q] Captivate USB charges but no data connection - flashing stock w/o ODIN

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!

[Q] Windows "USB Device Not Recognized" error

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?

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

[Q] Yet another no pc connectivity problem

Hello,
I know that there are countless other threads about this issue all over the Internet, but many of them are from a year ago and none of them have helped me yet.
I've installed every driver recommended from these threads, I've restarted my phone, my computer(s), tried a different cable, USB Debugging on and off, reformatted the internal SD card, and still no luck. Kies doesn't recognize my phone. It doesn't show up in device manager or as an extra drive.
Using TW Launcher. I plug it in, select Mass Storage, hit "Connect USB Storage." It says that USB storage is in use. Yet there is no activity on my PC to indicate as such.
I can't get my Captivate to connect to a computer.
It used to connect just fine up until I upgraded to Froyo.
Is my phone a hopeless case that needs replacing, or am I missing something along the way here? I'd love to root it or at least roll back to 2.1 somehow.
Thanks so much for looking and for any help.
Reboot into download and connect to computer, see if that works.

I had a similar problem and it was definitely a hardware problem. At first it was recognized but then it would only charge via the pc - multiple windows 7 computers would not recognize it. However, a few times it would start installing and then say "disconnected" or something like that. One of those times that I "jiggled" the connector on the phone, it started installing the driver and I didn't touch it and it finished and worked. I disconnected and reconnected and nothing again... I got another refurb and no problems at all.
Well I'll try a few more times. Just glad the Thrill is almost out and I can enjoy that one for 10 months before something better comes along
Thanks for the help

problem solved but new problems with updated i897

I got the updated version of captivate from att center with froyo with gps fixed. Now two new issues: I rooted the older one and used titanium to back my datas.
Now with new one, I tried to restore two roadblock.
- Windows driver no longer works with this new version. I even removed the drivers from registry still no avail. (SGH-i897_Captivate_USB_Drivers_5_02_0_2.zip)
Once re-install then I choose USB storage version and driver installs but systems can not recognize the device and appears as unknown device in the device manager.
- One click root application can no longer recognizes this new version. This is the app I used to root and unroot the older captivate. GalaxyS_One-Click_Root_All_Models
However, I believe this might be due to the first problem, the driver is not being recognized.
Any help will be appreciated. Thanks,
Try a different USB port

Well well... so I guess I'm not the only one with this "unrecognized USB drive" issue. I too exchanged my old one because of audio jack issue from at&t service center on September 3rd. The GPS is amazing but I cannot mount it as SD card. Tried everything regarding installing drivers. I tried all the USB port available on my system, still no go. Uninstall and removing every single trace of registry. Still no go for mounting as drive. The Max I can do is mount as MTP. But as soon as mount as storage, it pops up saying 'unrecognized USB drive'. I have literally invested more than 24 hrs without any fix. Only good thing about this is that the GPS is a killer. I drove from Indianapolis to Louisville and it didn't deviate even for a second from the route even when I sometime reached a speed of 90mph. If anyone know how to resolve the issue of mounting the phone as storage device without getting the USB error, your work will be highly appreciated.

Try a different USB cable. The one that comes with the Captivate stinks. I had no problem mounting my Captivate on my old computer (which is a Mac), but when I got a new iMac, my phone refused to mount. After several hours of screwing around, I tried the USB cable that came with my wife's Motorola Bravo. Damn thing mounted right up.
If I use the stock Samsung cable, nothing. If I use the Motorola cable, flawless.
Give it a try.

That will work for your situation

It has to be something with voltage. My Samsung USB cable (the one that came with the phone) worked just fine with my old computer. When I upgraded my computer, the cable no longer worked.
I did notice that if I plugged it into a USB hub instead of directly into the Mac, then the phone mounted...but the connection was slow and it dropped all the time, so it was basically unusable.
@guyenxda000...try a different cable before you decide it's not going to work. It actually might.
Okay, I had alternative cable in my car and brough home now i can connect. Now, phone is recognized if I choose kite usb mode, and can access sdcard if i choose usb. but still it is not responding to one-root-click application i mentioned earlier. is it not supposed to work with the newer captivates? if not, anyone knows an app to root it?

First, make sure you're not mounting the phone before trying to root it. Make sure USB debugging is turned on, then plug in the phone and just leave it like that. The root process won't run if you have the SD card mounted. Also, make sure you have the latest drivers. Then run your one-click root.
I used SuperOneClick on mine and it worked the first time. My build is an 1101, so newer phones might not be supported. I have no idea if it makes a difference or not.
Dude thx for ur effort for help. But all ur instructions seem to imply i am doing first time. If u read thru this post i already done successfully with my older version phone which means i must have followed all the steps u described. if u really meant to hlp can u clarify build 1101 u kentioned? If u do that it cn help me someway. Thx
okay lot of progress yesterday, but hit a roadblock.
changed new cable, i had to put the phone into debuggin mode, which I forgot. Now I tried one-click-root app, it does put the phone into recovery mode, but still fails to root saying e-signature verificaiton failed or something.
went through a hard manual way:
copied the rageagainstthecage-arm5.bin into sdcard.
supposedly that should open the terminal emulator in super user mode so that i can mount the /dev/block/st19 into /system as a RW mode, which enables me to copy the other files such as superuser.apk into /system/app folder.
Howeer rageagainstthecage-arm5.bin does not seem to do the job. instruction says after 'spawn child' message restart the terminal emulator which should have turned into # command prompt rather than $. I believe # means enabled to do a root privileged stuff like remounting /system folder. Anyone has hit this roadblock? Thanks,

[Q] Connecting to computer problems

Hi all!
I have a Nexus One running CM7.2.0 with Clockworkmod Recovery. My computer is running Windows 7.
I want to connect my phone to the computer in order to return it to it's factory state with an official shipping rom and stock recovery image.
However, I've run into a problem which I've been having for quite a while now; when I plug the phone into the computer via USB cable, it charges, but nothing happens on the computer, and nothing happens on the phone.
I've tried different USB cables, and different computers.
If I push the part that goes into the phone port to the right, the computer will make a noise as if to say that something is connected, but then it will be unable to install the correct drivers, and will say "USB Device not recognized" It comes up as an "Unspecified" device in Devices and Printers, and in "Unknown Device Properties" it tells me that "Windows has stopped this device because it has reported problems. (Code 43)".
I have a feeling that the problem is the port on the phone, but I wanted to ask on here first to see what other people thought. Why is it that the phone charges correctly, but won't be recognized on the computer?
I might just add that this problem first started when I installed a device manager program that allowed me to see my texts and things when the phone was plugged into the computer. It was a while ago, and I think I remember (not entirely sure though!) not safely ejecting the phone before unplugging it, and then 2 minutes later when I went to plug it back in, this occurred. Whether this is related to the problem or not I do not know.
Also, I'll add that this problem has been occurring for quite a few months now, but it is only recently that I have noticed that when plugged into a wall charger, the phone charges much slower than it used to, and the charging light will go on and off every so often. This suggests port wear, but this started happening quite a while after the connection problems happened.
Anyway, thanks to all those who respond! I am keen to work out what is wrong.
Thanks,
Simon
Also I'll add that the SD card works perfectly fine in an SD card reader USB thing!

I'm not sure you properly read what I said..
My phone doesn't work on any computer I try it on. All other USB devices work fine on the computer I am currently using. This means that it is not simply a matter of following the steps you linked, because the problem is not related to a windows error.
BTW, learn how to read properly.
Youshuold change usb cable or or rest the phone.but first of all buckup your data after that phone will stat newely so bug will be gone
