Have you installed the Samsung drivers?

yeah i've tried installing the drivers. the phone isn't even putting the usb icon in the notification tray anymore. just starts charging and that's it. i go to usb settings/mass storage and nothing. any ideas?

I got that too, I just put the usb cable in another usb port on my computer and tadaaaa: problem fixed

I had this issue and read in a forum (not sure where wish I did to give credit) where u need to format your internal SD memory (the built in 16 gig SD) I did that and it started to work again.

How about Menu > settings > applications > usb settings > ask on connection.....

I had/have this problem sometimes too. choosing "ask on connection" usually works. I find that if you select anything other than "mass storage" then exit out, then go back in and choose mass storage, it works again.
Usually only have to do it once after a factory reset or on a new phone

I find my connection to be hit or miss. The pc picks up the drivers fine but doesn't mount the phone as a drive. Kies is a pain to get going too. I read on here that you need .net framework 4 and also no file names over 16 characters, and without kies I think you need to be in debug mode on application settings. I still need to try the short file names and see if it improve it but I never really hook up to a pc anyway, my father has win 7 and I have kies on his computer. I have linux mint 9 on my own so I rarely get to fitz with it on a windows machine.

I'm having this problem, can't get usb debugging mode to turn off. It immediately turns on when I turn it off. It's as the just says, "yeah, you can uncheck it, but I'm gonna leave it on."

Cannot Connect to Mass Storage

Hi Guys,
I have just bought the samsung galaxy s, and it connect to the internal mass storage of the device, i have win 7 and it says device driver not found.
I dont have SD card on the device.
Thanks

I think all you have to do is to slide top panel in SGS down and click on USB notification to mount your phone storage.

Personally didn't figure it out till a week into owning the phone that there was an extra step
involved in activating mass storage mode.
As mentioned, just slide down the top taskbar, click on the usb alert box and mount.

Thanks guys i knew that, i have been using android lately on desire. Well i solved the issue by downloading a driver.

same here haha. had the phone for over a month and still couldnt get in mass-storage.. till i figured out i had to do the "following step "

Sorry to highjack this thread but - do we need to use the "safely remove hardware" on the PC and "remount SD card" on the phone before unplugging the USB cable?

Supposedly, one should firstly "safely remove hardware" via the usb window on the PC anytime there is
a need to sever a USB connection to a device.
However, in all honesty, I only know a handful of people who ever do this, and I'm not one of them.
Most if not all products with connections via USB won't be affected when it is just manually unplugged (disconnected from usb port)
unless you have data being transferred while you unplug/disconnect the usb device.
But for devices with their own proprietary OSes (PMP, MID, MP3 players, phones, etc.), it is recommended
you follow whatever steps they provide for you in the manual.

Thanks. I kinda freaked out today when I clicked "safely remove hardware" AND "remount internal SD card" on the SGS. The device later failed to recognize the internal SD card and screen went black. I thought I had bricked it and killed my internal SD. From now on, I might use an external microSD card to transfer movies into my device.

[Solved] USB Mass Storage Mode Issues (CM7)

I am having issues with the activation of USB Mass Storage mode on CM7 v7.10. When I first connected my nook (just got it yesterday), I was able to enable mass storage mode as per normal. However, after this it's just stopped working!
There's nothing wrong with the cable afaics because the empty drives come up on the PC (Win7) no problem, it's just that the nook doesn't detect that the USB is plugged in and so never gives me the option to enable Mass Storage mode. I have had success once running ROM Manager's 'Fix Permissions' function, but since then it's not made any differences. The issue remains on multiple PCs with multiple cables.
Anyone got any fixes for this issue?

+ can you wiggle the micro-usb end a bit to see if anything better?
+ do you have the "usb debugging" check?
+ do you see the usb icon displayed on the NC notification bar?

- No wiggling makes any difference
- Tried with USB debugging on and off - no difference
- No USB icon (but empty drives still show up on my PC) so there is some kind of connection going on.

If the empty drives do show up on the PC, it definitely some sorts of connection made, it's a good sign.
Now back on your NC, go into Storage, try to Unmount then Remount the uSD and see if it gets any going.
Note: leave the Debugging USB Mode on.

Might also be worth considering moving from 7.1 to the MiRaGe 7.2 build. I'm not saying there is a specific fix but using the later ROM may help and I think most people find it more stable, faster and problem free.

Yeah, I actually updated to KANG 7.2 this avo and the USB Mass Storage option is back!
Thanks everyone for your suggestions!

I currently having KANG Mirage 7.2 with Tablet Tweak but it did not work. I bought an OTG cable from ebay so I assumed it's bc the OTG cable. The Drive works fine on my laptop but nothing appears on the Nook.

Maybe a re-flash with the same ROM might do the trick?

I'll try to reflash sometime soon!
Will post

uSB mass storage
I had the same issue. Have the USB connected and while connected reboot your device once it has rebooted you'll be able to access the USB files on your device. You'll be able to see the USB signal at the bottom, which you can activate. You'll have to do this most likely everytime you want to access USB storage

I'm on MIRAGE 7.2 running off EMMC. SD card is in the Nook.
I shut nook off, plugged in the cable to my pc and started the nook.
5 drives show up but I cannot access any of them. The USB icon is in the tray on the Nook and it says "USB connected". Just above that it says, "USB debugging connected"
Anybody have any success?
After doing some reading I've decided to use ES-FILE Explorer wirelessly. Its very easy to use. You need to SHARE folders on your PC in order for it to access the files.

Playing around with the USB option some more, I didn't realize that you could TOUCH the message in the notification bar. When you do, it launches a program and from there, you turn the USB connection on or off.
Geeeeeeez........ya learn something new every day.

media transfer

using windows XP i can not get the nexus 7 to show up to transfer files. not sure if i need a MTP driver (which i cant find anywhere) or if there is something else i need to do i would hate to have to transfer media to a different PC to get what i want on there.
any ideas

From the charging notification, make sure it is in external storage mode to allow the USB PnP to recognize the device for file storage.

I plug the nexus 7 into the PC via USB. N7 says Connected as Media device. but nothing shows on PC

I dont have my N7 yet, but looking at my Thunderbold ... There should be an option for Disk Drive when you open the notification that appears when plugged in by USB. When the Disk Drive option is enabled, the PC will detect the drive and treat it as an external data source.
Perhaps someone who has an N7 in hand can chime in.

yeah no thats not the case here all my other Android devices work fine including my Gnex running JB 4.1 still connects the same way. its just the N7 that wont show up. i can ADB to the N7 but nothing else.

ICS and charge-only mode?

Yeah I know its gone. Is it possible to restore this functionality in ICS? I know virtually nothing of Android programming otherwise I'd attempt to tackle this missing feature.

Plug it into a wall. That's charge only
#unseen

No kidding?
Aside from that, if I don't have my charger with me and a have a data cable I can plug it into my computer to charge. Normally this is not a problem but here at work we aren't allowed to connect "personal" devices to work computers. Doing this causes the SD cards to mount. I don't want the work spies (yes they do monitor us closely) to see drives being mounted. Fine I can unmount them via Windows. The problem with that even though they are unmounted the phone is unable to access either SD card until I unplug it. I just want to charge the phone and I don't always have a charger with me.
Edit:
Well I have somewhat of a work-around. If I put the Bionic USB into MTP mode and plug it into my workstation (at work) it will charge if USB debugging is enabled and it won't connect any drives. With that I can charge and I can simultaneously access internal or external SD cards.

Looking through system files there is an apk that says chargeonly.APk. maybe that's the key

I used QuickShortcutMaker to create a shortcut to the Charge Only mode which that APK refers to. When I ran it, the screen with the battery came up that you see when you are charging it while the phone is turned off. I then plugged it into the computer, and it mounted both of the SD cards, even while still showing the charge screen. It appears that this isn't really going to work the way he wants.
MTP doesn't mount the drives as drives per se. It mounts as a media device, which shouldn't show up the same way on the computer as drives obviously. This is the de facto charge only mode in ICS, though it does stuff other than charge. PTP mode should work more or less the same way too. I think that MTP can interface with programs like Windows Media Player and Winamp, while PTP mode is for picture programs.

Yeah when I plug in with MTP I do get a Media Player type icon in the systray. If I click on that I get the auto-run type screen and select "take no action" and the icon goes away and it will continue to charge (so long as USB debug mode is on). I tried select the "always take this action" option but for some reason it doesn't remember it. I think it has something to do with the way work has the group policies setup.

FWIW - I was struggling with this, as I needed to charge my phone, but wanted to listen to music...
Using the "Camera(PTP)" mode serves the same purpose as "Charge Only", in that I can still access my SD Card from the phone, and it charges fine.
Hope this helps!
