USB Mass Storage Issues - Vibrant

When I plug my Vibrant in by USB on WinXP I am getting a device not recognized error. I get nothing when plugging into a Mac. I've tried multiple cables and I have changed the USB options to each option.
I have rooted the phone and installed the GPS fix.
Any suggestions for fixing this would be appreciated.
Thank you

Load the galaxy s drivers, will work after that

What about for Mac OS? The phone doesn't show up when I mount the cards. Is there a way to get mass storage to work on a Mac that doesn't involve turning on USB debugging?

I'm not a mac person, sorry, hopefully someone else can chime in on that.
Edited, if you go to the thread i linked, the op states for linux and mac the android sdk drivers should work, hope that helps.

When you plug it in are you sliding down the notification bar and selecting the USB Connected > Mount option?
As well when you are done you have to Unmount when you are done.

Yeah, like kizer said too, mount the device. I was assuming that step is s.o.p.

Yes, I had a G1 for years and that always worked perfectly. The only way to get my Vibrant to show up though is to use USB debugging mode.

I just did some quick googling and it seems mac users are doing exactly what you said you don't want to do, setting usb debugging on, and that seems to be a quick fix. I'm sure there is more info out there in cyberspace, but if debugging works, I say go with it. I always have debugging turned on, incase I need that oops adb action.

With the OP having one post who knows if he/she really knew it had to be mounted. LOL Figured it wouldn't hurt just to mention just in case.

When i use it on my Mac, i have to enable USB debugging. Then both drives (internal and SD) pop up just fine.
So it looks like someone answered this, just confirmation then.

Another theory
My Vibrant has mounted normally and without any problems on WinXP sp3 and Win7-64 systems, but I have also run into the occasional system where it will not work at all.
On the systems where things worked normally it was never required that I load a special Samsung USB driver for the phone. The standard mass storage drivers included with Windows worked fine.
My new theory is that there may be a drive letter collision issue in some cases. On the laptop that I use with my phone 90% of the time the phone always mounts as drive G: and H:.
On other machines I have noticed that the phone always seems to mount as G: and H: even if E: and F: are available. I'm not sure how/why it always gets mounted using those letters. It may somehow be defaulting to that because G: and H: were the first letters available on the first system I plugged it into.
I have a Win7-64 desktop machine that will not currently allow the phone to connect. This particular machine already has G: and H: assigned to hard drive partitions.
I will probably experiment with temporarily changing the letter assignments to see if I can get the phone to mount. It's worth a shot I guess.

Sorry, I didn't go into as much detail as I could have.
I've installed those drivers listed here as well as any other I could find. I've tried USB debugging mode, changed all the USB modes listed. I've mounted and unmounted the SD cards using the settings menu when doing this.
Is it possible that there is some background service that should be running? Or is it possible that something in the firmware is screwed up? I guess it's also possible that the USB plug itself is messed up?
Thanks for the help.
I used to use this forum years ago when I had a HTC WinMo phone, it seems to have lost any record of past posts due to inactivity.

As kizer stated in his post, are you mounting from the prompt on your phone's notification bar? Once plugged into your pc or mac, you slide down the notification bar from the top of your home screen, click on the usb prompt then select mount. Thats the only step you didn't list that may have been missed.
Edited - the prompt in the notification area may say mass storage, my home pc fried last week so i cant test it to get you the specific verbage.

I don't get any prompt at all. At this point I will just install CM6.1 when it comes out and hope that fixes the issue. It's usable for now. I can transfer files using WiFi File Explorer for now.

It helps if you know if you are USB 1.0 or 1.1 or 2.0....or even 3.0.
Also, are the USB ports powered ?
Are the USB ports on the computer in question filled with dust and dirt ?
Contacts corroded ?
Are the ports recognized by the operating system correctly (you know, drivers loaded since it's old arsed WinXP) ?
Do you undertand how to operate a computer at a higher level than just being able to install viral apps ?
Malware ?
Trojans ?
I could go on all day.
It works fine here, on Win7x64, WinVistax64, and *nix.

That is bizarre you should get a least something in your taskbar.
Click for larger photos if you like.
Heres what my looks like and of course I have the taskbar pulled down so you can see it.
Below that is the box you would click to say connect it.

I did have a freind who didn't realize he could pull down the notification bar. Could that be the case here?
Op, you do know you can pull down the bar at the top of your screen, the one with your clock and battery icon etc., put your finger up there and swipe in a downward motion.

I have tried this on a corporate IT managed WinXP system (running Kapersky AntiVirus) and a currently updated Snow Leopard MacBook. I could give details all day as well. Both are in good condition and very likely not the issue.
Seriously, if you have nothing useful to say don't say anything at all.

they don't understand i had this issue too man and i fixed it.
first go to that link and download those drivers... use the uninstall app to uninstall the drivers off your computer.
while your doing that go into your phone setting>applications>usb settings
make sure it says "ask on connection" (you can change it later) go back and go to development to turn on usb debugging.
reinstall drivers, connect phone wait for the drivers to load. the un-connect phone turn debugging off.
and it was fixed for me.
hope this helps

Help, applied 4zroot and

Now I cant see the tab on my PC, I noticed the option to mount does not pop up when I connect it I need to pull it down from the tray on top and hit mount, but even then I dont connect to my PC, I do have the usb symbol in the tray of the tab but its not showing on my desk top. It also makes a different sound when connected than other USB devices and different from before 4z. Other than that Tab in functioning as always.
Any clues

I'd be interested in seeing the answer to this too.
All I've done to my tab is flash the Euro rom and bell modem to enable phone calls and then I did z4root to root my device. I tried to plug it into my computer yesterday to transfer some files over and I would get the mount prompt on the device but when I click it, my tab never shows up on my computer. Anyone know how to remedy??

Have you tried reinstalling drivers in the PC?

Dumb me! I'll have to check this when I get home, but I'm pretty sure I left it checked. Glad to hear it worked so I'm sure that's the cause. Thanks!

STILL having trouble with download mode!

Okay.. I'm almost on the verge of being desperate for a fix for this. I still can't get my windows or Linux computer to recognize my phone in download or mass storage mode. I've talked to adrynalyne and he told me to try heimdall. No luck. There's a new post made about this issue nearly every day on here.
At this point I would be happy with finding a way to flash the modem without using Odin. I know we have a ton of AMAZING devs here, do you guys think we can try to figure this out? I think it is definitely something beyond drivers, considering the sudden increase in people having the problem.

Maybe this is a dumb question, but have you tried all of the usb ports, even the ones on the back of the pc? And how about rebooting phone while connected to pc? Usb debugging on, off... all of these worked for me at one time.
Sent from my rooted froyo Fascinate

Its not a dumb question. Thank you for trying to help. Yes, I have tried just about anything you can think of. Tried Linux, tried windows, tried 64 bit drivers, tried 32 bit drivers, tried every single USB port. Nothing.
Sent from my SCH-I500 using XDA Premium App

Firewall? I remember a firewall causing problems with my old phone. I didn't check for my fascinate, got lazy and just turned it off before doing anything. I highly recommend not being connected to anything other than your phone if you do turn off your firewall.
Sent from my SCH-I500 using XDA App

Thanks for the suggestion. I have even tried that. As far as I know Ubuntu doesn't really have a firewall. although I could be wrong. And none of the devs seem to be able to come up with anything either.

Based on the described symptoms, I would say either the USB port on the phone has bit the dust, or you have a bad USB cable. I would try a different, known good USB cable and see what happens.
Posted from my EB01 SuperClean Fascinate with Voodoo

A little far-fetched, but I'll try anyway ...
From Windows:
- Don't plug in your Fascinate
- Create a new SYSTEM environment variable called "DEVMGR_SHOW_NONPRESENT_DEVICES" and set it to "1" (without the quotes)
- Open Device Manager
- View / Show Hidden Devices
- If you see any of the following, delete them (right-click on the device and select "uninstall", check the box that says "Delete the driver software..." if available:
ADB Interface / SAMSUNG Android Composite ADB Interface
Disk Drives / SAMSUNG SCH-I500 Card USB Device
DVD/CD-ROM Drives / SAMSUNG UMS CD-ROM USB Device
DVD/CD-ROM Drives / SAMSUNG CD-ROM USB Device
Modems / SAMSUNG * (* = anything that starts with SAMSUNG)
Ports (COM & LPT) / SAMSUNG *
Universal Serial Bus Controllers / SAMSUNG *
- Uninstall "SAMSUNG USB Driver for Mobile Phones" from Control Panel / Programs and Features
- Re-install the proper Samsung drivers "Generic_CDMA_i500_Showcase_USB_Driver_V1.3.550.0.msi".
- See what happens when you plug it in next time and let us know

So I followed the instructions to a T. It installed all of the drivers when I plugged the phone in. But get the USB device not recognized when i go to download mode.
Strangely, Odin does recognize the phone when I put it into dun mode. But it won't flash anything.

I would definately try a new cable. I used one that was identical to the one that came with my fascinate but it was from an old phone of mine and it had the same problem, and make sure its a "data" cable

Sorry this didn't have any positive effects for you. I have to agree with the others at this point ... try a new cable. If that doesn't work ... um ... you may be in a bad place

Maybe I'm missing something but how do I mount usb storage?

Hey xda
I got the Galaxy Tab 10.1 at io and I can't seem to figure how to Mount it. Theres no mount notification or anything like the phones I have. Am I somehow missing something painfully obvious?
Sent from my HTC Glacier using XDA App

Well, if you were at I/O, I assume you know how to use ADB.
Follow the rooting guide in the development section and use adb push / pull for data options for the meantime.

I'm guessing they want you to use the kies application which is absolutely horrible..
hopefully someone comes out with a workaround soon

turn off USB debugging and it will work essentially the same as USB storage but using the integrated Kiel or whatever on the device

FWIW, I plugged the tablet in my macbook pro and got a drive on my desktop showing the content of the "sdcard" on it. Nothing special, no drivers involved.
USB debugging was enabled, although I don't think it's relevant for this.

Interesting, I had to disable for it to work on my laptop. I thought it wouldn't be relevant either but it made a difference for me. Was in Windows 7

good find. One of the first things I do when I get an android device is enable usb debugging and I never turn it off again. I guess I'll have to do that now. Oh well, it's a hell of a lot better than having to use the kies program on your computer.

On ubuntu (natty) I had to turn off debug to get mass storage to work and vice versa. Only seems to do one at a time.

Can anybody tell me how you can use an external drive with the 10.1v if there is no usb-enterance? Am I missing something ??
And can please anybody post the usersmanual of the 10.1v?

Thanks everyone, I was pushing everything. One of the first things I did when I got it was turn on usb debugging. Once I turned it off it mounted fine.

It should work fine in Ubuntu even with USB Debugging enabled. See my guide here:

cant transfer pictures to computer?

I tried to connect my nexus 4 to my PC , but it would not recognize it under my computer like it should so I could drag and drop. I tried mounting it as MTP and PTP and neither would be recognised.
I ended up transferring my pictures using adb, but I don't know why it didn't work the standard way.
Anyone have any ideas?

Have you tried using drop box? It's really simple and automatic. Just set it to upload only on Wi-Fi

Is Android debugging on?

Is it having trouble with installing the MTP driver ? Try turning off USB debugging, I couldn't get MTP to work until I did that.

Maybe you've got the same problem that we have here: http://forum.xda-developers.com/showthread.php?t=2005437
Maybe you try:
A different USB port
A different USB cable
Uninstall existing drivers + installing the drivers again
A different computer
And if all that didn't help you can join us in the above mentioned thread. We don't have a solution yet but maybe we can draw some attention to the issue.

All the driver seem to be fine and the nexus 4 is recognised via adb. It used to work before so I don't what's wrong.
Edit: yes USB debugging was on

Ok, but that's actually good! What happens if you plug it into a different usb port?

It says your device could be faster with USB 2.0 and then it is not recognised.

Now that's really odd. Have you tried a different USB cable?

I'm using the stock lg cable. I'll try with my nexus 7 cable.
Edit with my nexus 7 cable it says connected by the windows 7 notification, but when I check in computer it does not show anything

But you have seen your N4 in the explorer before, right? I have seen my N4 on my GFs windows machine as Nexus 4, not as a storage device.

And what happens if you double-click it there? Can you get your pix then?
Edit: I didn't find my N4 as a storage device, so you can't find it as a letter in your explorer but a real device.

If I double click it it takes me to nexus 4 properties. My nexus 7 does not show up in my computer either that's what bled me to think it has to do with 4.2

Maybe someone with a win7 machine can chip in here, since I think it is a windows problem. I am on a linux laptop, so I can't really help you there. But good luck anyway!

By George, I fixed it I went into device manager I right clicked on SAMSUNG android phone then nexus 4 under that section, then I clicked update driver. Then I clicked on browse my computer for driver software after I clicked on let me pick from a list of device drivers on my computer and I select mtp. The all of a sudden auto play came up with my device connected as a camera (ptp)
Now all my phones show up under my computer

MTP uses a completely different driver from ADB. So you can have one working but not the other.
