[Q] Captivate USB problems

Hi everyone,
I have an AT&T Captivate SGH-i897 (2nd hand) and i can't mount the phone to my laptop (winXP 32bit). When i plug in the cable to the phone and then the PC i get the "device not recognized".I've donwloaded the Samsung drivers from the xda wiki page and extracted them and tried to update the driveres via Device Mng ,but didn't work.Also dl'ed the Samsung drivers 5.0.x instaled ,and still nothing.USB Debugging is on...
So to recap,my top can't recognize the phone('s internal sd card) so plz help ???????

Try this, go into usb settings and choose "mass storage"

install kies

I would also recommend trying to fully uninstall all the drivers that associated on your pc with your phone (samsung or otherwise), and then reinstall the drivers before you plug in your phone. Then try to reconnect.

Just covering the basics. Assuming your phone is working correctly.
You have tried multiple USB ports on your computer, particularly those on the back if it's a desktop.
You have installed correct drivers (x86 or x64)
" for the correct operating system.
You have uninstalled the drivers before trying to reinstall.
You've tried to get Windows/ Mac to find them online (assuming you're using versions of OS that support doing that)
You've first tried Kies mini before full version, uninstalling in between. (Kies full version isn't supported for US, there are workarounds, but that's a different discussion)
On the phone you tell the phone to connect 'USB storage' (from the pull down menu after connected or in the settings)

I too am having problems with USB connectivity on a notebook with Win7/64. The usual failure mode is Windows not recognizing the USB device. I have followed ZBigT's basics, step by step and still cannot connect.
FWIW, my registry is awash with Samsung entries, some of which cannot be deleted.
I've even tried the AIO Toolbox application (to install the 64 bit drivers) to no avail.
Any other tips?

Yes. Still no love. Have tried:
usb_drivers_GalaxyS_x64
SGH-i897_Captivate_USB_Drivers_5_02_0_2
mini-KIES
Kies
AIO
uninstalling reinstalling each time
When I plug in the Captivate, any of 3 USB ports on the laptop, Windows gives the "Unrecognized Device..." message.

Go to settings/about phone. Look at the very bottom to see what rom you are running.

FWIW, I also have a Win7/64 desktop with the usb_drivers_GalaxyS_x64 installed and that works fine; can connect see "drives", use ODIN, adb commands etc.
It just the notebook, which I would like to be able to use to connect, especially when I travel, which has issues.

Check in program files for a Samsung folder. There may be remnants from old drivers that need to be manually deleted.

Thanks for sticking with this. I was able to connect. I as focused on the Registry remnants, but your advice to clear out the Samsung folder in Programs worked. Thank you.
Additional comments: I am now running the Dlev ROM, it's OK, but when I plugged in the USB cable, just to the phone, it launched the Alarm Clock app! So I deleted that.
Then on the first of my four USB ports I got a USB driver failure to install, then the Windows Unrecognized USB device on ports 2 & 3. On port 4 it worked. (This is a Lennovo/Thinkpad notebook.)
I used the usb_drivers_GalaxyS_x64 package as that also worked on my desktop.
Thank you very much.

USB Mount Issues (CM7)

Hey, everyone, I tried posting about this in the CM7 general discussion thread, but no one seemed apt to respond.
I think this was a problem that popped up in the 60s or 70s in terms of nightlies, but I'm having it again now since around the 155 mark.
I'm on 160 and when I plug my NC into the USB cable, I no longer get any options to connect for file transfers in the notification area. If anyone could help me out with this, I'd really appreciate it. It's just so perplexing and no one seems be having this issue except me. If it's user-side error, that's fine as well, I'd just like to know how to fix it.

1. When you plugged the NC in, did the PC recognize any "removable" drive?
2. In the notification area, did you see any other indication?
3. You run CM7 off uSD or eMMC?

1. No, nothing comes up.
2. The notification area remains blank.
3. I'm running it off eMMC.
Thanks for taking the time, by the way!

If so, unplug the usb cable then replug in a few times and see what happens.
If still nothing, try to use other usb cable.

Oh, btw, have you had Nookcolotweaks app installed?

I do have Nook Tweaks installed, yes. I'm using the cable that came with the Nook, but I'm not sure I have any other cables around.

Do make sure you check OFF the USB Host feature (reboot and reconnect)

I gave that a try, too, but still nothing. So confusing!

Don't be so hard on yourself.
Let try it on different computer if you have.
Also try difference usb cable.
Last, if nothing works, update latest nightly build

When you disconnect and reconnect the nook in testing/trying to get it recognized... unplug usb cable from computer... its made a difference at times.

I know this sounds basic but in applications-settings ensure you have usb debugging checked. Sometimes when flashing different nightlies, settings change.

Thanks again for all the help, everyone! I made sure USB debugging was checked and tried unplugging/replugging the cable, but there's still no notification coming up.

A new development:
I tried connecting it to my Windows PC instead of my Linux and it brought up this message that said it didn't recognize the device. I also tried to get ADB to see it and it can't. Does this information help or am I in trouble here?

Next time, do clearly indicate that you are using Linux or Windows. I'm sure many members here are Linux but still far less support than Windows world.
When I provided those suggestions in previous posts, I meant in Windows.
Anyway, back to your issue.
1. "it didn't recognize the device" because of missing adb usb driver. You need to get it installed first in order to use ADB, however it has nothing to do with your usb mass storage function. For now, you don't need to worry about it just yet.
2. Back to my question before, have you seen any "removable" on the PC (Windows)
Along with USB Host uncheck, if still having problem, I would suggest you either downgrade to the earlier versions or wait until tomorrow and update with another nightly build.
Good luck

I have the ADB drivers installed in Windows, as far as I know. I've used it before.
I typed "adb devices" into the prompt and it doesn't see the NC at all. Since one of the nightlies seems to be what prompted this sudden change in connectivity, I guess I'll just hope that one of the new ones can fix it. Thanks again.
Also, Windows doesn't show anything "removable" except for my external HD.

Try to disable usb debugging as you can still use ADB over wifi. This should always put the device to usb storage mode when connected.

I tried this out and even ADB wireless can't connect to my device. I even re-installed the ADB drivers in Windows to be sure the problem wasn't on that end.

If you're using ADB wireless, no need to install any driver on Windows PC, you just need 2 files: adb.exe and AdbWinApi.dll, to connect to Android device.
If you've installed ADB drivers, you might want to remove it as this might mess up usb storage.

Alrighty. I have those two. I've connected my NC to ADB both wirelessly and and with the cable in the past, so this should all be straightforward anyhow. It just plain refuses to cooperate.

Go to the Marketplace and download "Nook Color UMS" app. Follow instructions and it will mount properly. I had the same issue used it and it mounts proper through the app.

[RESOLVED] USB not working

I've having a problem with my PC not picking up my phone when plugged up. It will charge, but that's it. I don't get the drop down box to select my connection mode. Here's my setup:
Android version 2.3.4
Gingervolt 2.0
SW version: VS910ZV7
Debug enabled
Default connection mode is internet connection
Connected straight to USB port (no hub involved)
I've tried taking the battery out for a few minutes and that didn't work. I've tried toggling the default connection mode, but that does nothing.
I'd like to upgrade my CWM, but can't because of this.
Any ideas?
***EDIT***
Well for some odd/unknown reason my USB connection is working again! I have done nothing to my phone since flashing Break Out ROM 1.1 a while back and the USB was still broken after that. So, while this makes absolutely no sense at all, I'm thrilled to have it back!

If you want drop down box to select connection mode then go to settings/connectivity and check always ask (if its not already checked) i dont think the computer will show its connected unless mass storage is selected and your sd cards show up on computer. When in internet mode its probably fine just run the program to install cwm recovery. Thats what i did to make sure computer was reading the phone. Someone else may have better input on the subject

I've had problems before when not using the original LG cord. Are you using something other than that?

"always ask" is checked, but it never asks when I plug it up to my PC. If I switch default connection mode to mass storage my PC doesn't pick up my SD card either. So mass storage nor internet connection mode works. It will however, at least charge.
Yes, I'm using an original LG usb cable.

Have you verified the SD Card actually works by going into a File Manager and seeing if you can read the files in your SD Card?

Yes the SD card works. I can browse the files on it with Root Explorer and CWM picks up the backup images on it.

Have you only tried 1 port on the PC or multiple? If you can, try a different port or a different PC.

I should have included that in my original post. I have tried every USB port on 3 different PC's. Two HP's and one Dell.

Any other suggestions? I've been searching the net for days now and can't find a solution. I'm beginning to think I have a hardware problem. Is there any chance this could be a software/configuration problem?

[Q]Does not show GT-N7000 when connected to pc

hi, when Rocket Rom 7 (ics) came out, i installed it. after doing this, when i connected my phone to the pc, the system detects the phone as Samsung_android and shows 2 removable drives in the system. however, if you click on them they dont work
it no longer detects my phone as GT-N7000
what i have noticed: when i connect the usb cable, the phone doesnt show "MTP connection" anymore... instead, it shows USB connected.
what has been done:
flashed rocket rom 10, nogo
reinstalled kies: nogo
reinstalled win7 (yes i actually did that even tho testing on other pcs showed the same issue)
the phone still charges and the only way i can connect my phone to d pc to view files is by clicking "usb storage"
any advice on this?

Uninstall kies, and just install driver (find latest from toolbox on my signature)
use different USB port, and dont use any extensor cable to connect device.

hi bro... didnt work... i dont think its the driver... its the phone... coz i tested another note, its working fine

My Galaxy Tab has similar issues. I believe it would be due to the architechture of the ROM forcing you to have to mount your device to your computer before being able to load the Device Internal SD, and the External SD.
Click USB Storage when it shows, this should pop up a window which has a Lil android dude, and USB Storage Message with a button stating 'Turn on USB Storage'. After clicking it, you can click 'Turn Off USB Storage' to unmount the device.

thanx for that.. hehe.. i stumbled across it the other day.. at least i can transfer files... but just dont like the fact its not showing...

PC not detecting Tablet.

[Edit, first post and I got the board wrong. -_-. I thought I was in the troubleshooting section, sorry.]
Hello,
I've bought a used Galaxy Samsung GT-P1000 running Froyo.JPJM5, Firmware 2.2, and Kernal 2.6.32.9, 27.7GB internal memory.
My problem is that I can't get the PC to identify the tablet using the USB cable.
What I do and what happens when I plug in the tablet~
(USB Debugging on)
I connect the USB cable into the PC first. I plug the cable into the tablet. A 'USB is connected' notification shows up. I open it, and click mount.
I look at my computer's monitor and there's absolutely nothing showing that it EITHER identified or not! It doesn't even show a popup.
So I went to my Disk Management to check if it was hidden or something. There's nothing. It just shows my regular hard disks and that's it. No mounted anything. I even looked into my Device Manager and all seems working.
(USB Debugging off)
Nothing happens in either the PC or Tablet.
Things I've tried-
1) Enable USB Debugging.
- Plugging in the tablet, restart computer, and then enable USB Debugging while connected.
- Disable USB Debugging, restart computer w/ tablet connected.
- Plug tablet into PC, and then restart tablet. (with USB debugging and not)
2) Get KIES.
3) Uninstall KIES and only download the USB_drivers.exe thing that comes with KIES.
4) Uninstall everything (including drivers) and getting Android SDK + update everything (about 370mb).
5) Install Ubuntu and trying to get it identified + downloaded Android SDK package and updated everything. (also did lsusb- it doesn't see the tablet)
6) Tried each and every USB port in my PC. (10 ports). [Note: My other Android phone works in any of them)
7) Tried my bro's and sis' comp (win7 32bit)
8) Tried my dad's laptop (win7 64bit)
9) I unplugged tablet, placed the memory card(2GB) of my Android phone into it. Plugged it in my computer and yet it doesn't want to see it.
10) I went to a shop because I thought the USB cable is broken or the port hub is broken. The guy took it and plugged it on his PC using my own cable. He identified the problem and said "It needs its software to be updated". I asked how much, and he said $15. **** that ****. If he can do it, I can do it.
Conclusions up until now:
Tablet knows that its getting hooked up by the computer yet it doesn't send any information to the PC letting it know that it's a mounted drive.
USB Cable is fine.
Port hub is fine since it can detect the USB cable on *usb debugging* mode and I can charge the tablet with the USB cable plugged into the charger.
---------------------------------------------
Note: I tried to root it using z4root which doesn't require a USB connection. It doesn't work. It would work and work until the application crashes and I can't re open it as it always crashes after the first try. I tried using the temporary root option and it would load forever. All in all, doesn't work.
Note2: I attached 2 screenshots. One for my Disk Management window showing my partitions while the tablet is connected (and I pressed Mount on tablet). Second, is for my Device Manager window showing that there no unidentified devices and that the USB devices don't show any Android connected, yet on tablet it says it's mounted.
Thanks.

I don't know too much about how to fix windows.
But when you are using ubuntu,
did you put in this line to your /etc/udev/rules.d/51-android.rules
SUBSYSTEM=="usb", SYSFS{idVendor}=="04e8", MODE="0666"
btw, the 51-blabla filename can be 51-xxxxxanything
once done
sudo /etc/init.d/udev restart
plug in your tab to USB port
then if you have your Android SDK, you should have adb?
do
adb devices
does it show your tab?

I did what you just said. There's nothing. :|

Hmm..
Out of idea.

If it isn't recognizing the sd card you could try another one. Format it in the tablet, plug it into the computer, put the update on the sd card and update that way and see if it gets recognized that way.

What do you mean by 'put the update on the sd card'. What update?
Anyways, what I tried is that I used another SD Card (128MB), placed it in, formatted it in the tablet, and plugged it into the computer. Nothing happened on the PC. :|
'adb devices' doesn't show any devices connected either.
(I wanted to confirm that 'adb devices' is indeed working so I tried plugging my Android phone (ST-GT602) and ran adb devices- it showed it. But not the tablet.)
Is there anything other than z4root to root a phone without a USB connection? Or is there anything that might trigger the tablet to let the PC identify it? For example, is there anything that I can place on the SD Card (through another connection.. using my phone for example), then plug it into the tablet, then run that application?
I don't care if it's for rooting or not. Perhaps it would help.

Why don't you spend that $15 at the shop?
Very curious why it works for him.

You might find the Android update online (ICS to GB) or something like that and try to flash a signed update but if your computer doesn't recognize an Android formatted sd card I'm not sure how you would get the card formatted and then get the information to the card. You might search for the update on your tablet, download it and flash it using stock recovery. Maybe getting it updated might work but I have no idea why an out of date tablet won't show up
Also you could try searching online for modified drivers for the device.
Par that I have no idea. Might have to go back and pay the 15 but I would ask the repair guy if you could watch step by step what he is doing.
Hope the best for you.
