[Q] My N1 Would not Prompt to Mount SD Memory When I connect it to my PC

I needed to transfer some files from my N1 to my Pc, so I connected it to my PC using the cable. I was expecting the black mounting screen prompting me to mount the SD card, but nothing happened. I restarted my device twice, but the case is still the same. What could have been wrong? I have not installed any app within this time, not removed any. I have used it in just ordinary daily manner, messaging and calling and nothing else. My N1 runs on Froyo, OTA. No jailbreak.
Please help. Thank you

u need to assign a drive letter to your SD card

Noob answer: is it on the status pulldown bar?

Do you have USB Debugging enabled?

Does the phone recognise that it's been plugged in (ie start charging)?

Similar problem
I am having a similar problem with my N1 running CM6 stable. When I turn off USB debugging and plug the phone into my Win7 laptop, I get the USB connected screen, but when I turn on USB storage the SD drive doesn't mount i.e. I cannot see/access the drive in Windows 7. The N1 status bar says USB storage is on.
Under Device Manager, the N1 shows up as Android Phone-->Android ADB Interface with driver version 2.0.10.2 dated 11/08/2009.
Any help would be much appreciated.

No, THIS is exactly the problem, the phone dies not recognise that it has been connected to a computer. It does start charging, but no sign of SD memory mount/unmount. Nothing. Just simply charging.

No, USB debugging is not enabled. I double checked it.

I guess that Windows also doesn't recognize the phone as anything (Device Manager doesn't show anything new plugged in)?
In that case, enable USB Debugging, and see if the phone is recognized by Windows.
If it is - the problem is somewhere in SW.
If it isn't - then it might be a faulty USB cable or connector (from any side - phone or PC).

same thing happens to me from time to time. restart your computer and that should fix your problem.

[Q] Can't connect my Captivate through USB anymore

Hi everyone,
I'm having issues connecting my Samsung Captivate to my computer. For about a week, it worked fine, I was able to transfer files to my phone but recently I noticed that the "USB connected" notification is not showing on the phone when plugged in to the computer.
Now, when I plug in my phone to the computer it just charges but doesn't comunicate with my computer. A friend of mine bought the same phone right after I did and he gets the "USB connected" connected when he plugs in his.
I tried using his USB cable but again, the phone is not recognized by Windows nor the phone detects it is connected to the computer. I've tried installing several USB drivers that I've come across on several forums, but nothing. I even downloaded and updated Kies to the latest version, but still nothing.
My phone is unlocked and NOT rooted, and I'm using Windows 7 x64. I've set the USB Settings to Mass Storage, even to Ask on Connection, but it doesn't ask anything when I connect the phone to a USB on my computer.
Sometimes Windows knows there is a device connected but says it couldn't recognize it.
I already did a factory reset, but the issue was not solved. I've tried connecting it to other computers, but still hasn't been able to connect my phone correctly.
What could it be?
Thanks!

Hmm. You have Mass Storage selected and up-to-date USB drivers. Try selecting USB-Debugging and Stay Awake in the Development option of your phone. If that doesn't fix it, then I have a few other ideas.

Make sure the usb door is completely open, it should click into place, some users have reported this solves their usb issues.

I did what you told me, but still my phone ain't recognized by Windows nor my phone is aware that it has been conected to a computer
What other ideas do you have in mind?

I'm sure usb door is completely opened

Have you tried using a different USB outlet on your computer? I had this same issue when I plugged my phone up using the USB outlet on the front of my computer then when I tried the one on the back of my computer it worked just fine.

Are you running a launcher app? I use launcher pro and can't connect until I change back to the default launcher with home switcher and launch it.

First off, think back. If it worked for a week and then suddenly stopped, what changed? Maybe you updated something on Windows or changed something on your phone. There's a reason it just stopped.
You can try using a free program called USBDeview.
It might do the trick for you and help you install the correct drivers. I'm thinking you no longer have them.
1. Download USBDeview (link is above)
2. Plug your phone in and open the program. Find all the HTC drivers-delete them
3. Unplug your phone and plug it back in
4. The correct drivers should install automatically
You can also try updating the drivers manually.
Galaxy S drivers (These are for ADB, but will work fine)
1. Click the Start Menu on your computer and right click "Computer"
2. Choose "Manage" --> it will ask you to continue --> "Device Manager"
3. Plug you phone in and look for it to pop up, probably under Portable Devices
4. Right click --> "Properties" --> "Update Driver" --> "Browse" --> "Let Me Pick" --> and navigate to the location you extracted the drivers to.
This is most likely a driver issue. I doubt your phone is messed up. You'll get it eventually. I also had a hard time getting my Captivate to connect. After uninstalling and reinstalling my drivers (more than once) it finally worked. One last thing, for now. When you uninstall drivers, also make sure you don't have any installed under your program list. As in, Control Panel --> Uninstall a program. Good luck!

A friend of mine, who bought the same phone on the same day as I did, plugged in his phone on my computer using my cable to the same port my phone was connected, and he did get the "USB Connected" notification on his phone

I did all that yesterday, but the device ain't listed in the USBDeview nor it shows up in the Device Manager

did you finally fix this problem? because I'm having the same issue here

Same here. It was working fine, I could connect to Kies, transfer music in Media mode and see both sd drives in Mass Storage mode. Then I rooted today and now I get nothing. In anything but Kies mode I get the Windows Bong of Recognition, but still not visible in Explorer. Also, my Home screen stays active instead of switching to the USB animation like it did before. I know this can't be a consequence of rooting the phone, can it?
EDIT: More weirdness, with the phone connected in Mass Storage mode if I look at My Computer in Explorer there are 2 extra drives showing, but they are greyed out and when I click on either of them it asks me to insert a card as the drive is empty. WTF???

UPDATE: I unrooted and managed to get my USB connection back to working. It is still a bit flaky as I sometimes have to disconnect/reconnect several times before it works, but at least it now works although it sometimes loses sync in the middle of transferring a file. Can't imagine why simply rooting the phone would cause the loss of USB connectivity. I am going to reroot and see if it occurs again.

OK, a rerooted the phone and this problem is now back. I have no problem connecting while in debugging mode. I installed OCD (non-Market apps mod) and when I turn off debugging and connect I get the Windows bong and see the USB icon in the Notification bar, but the MTP screen never comes up and I can't see the phone in Explorer (Mass Storage mode) or in WMP (Media mode). Kies can;t see it in that mode, either. I really don't want to have to unroot every time I want to look at the phone contents. Any ideas? PLEASE!

I'm having a similar problem - I installed the Perception ROM and immediately afterwards I can't see the USB connection at all from my PC or my Mac. The USB icon on the phone does not come up either.
I'm trying to get my hands on a different cable - but the weird thing is when I plug the USB into my computer the phone starts charging for like half a second and then stops.
This is really annoying. I tried changing the rom to Cognition 3.02 but that didn't change anything.

There are a few topics on this here on the forum - I would recommend the following:
How are you rooting your phones? Nobody has said exactly how they are doing this. Are you using recommended rooting methods? Or are you using some app found on the market?
Make sure you have USB De-Bugging is turned on.
Make sure you have it listed as ask on connection.
For those who can see the drives in Windows...
Plug in your phone and then pull down your notification bar and click on the USB connected message. It will give you an option there to mount your SDCard(s) to Windows allowing you to transfer files.
Kies is junk - I'd recommend uninstalling it as it seems to cause more issues then it solves.
Use the drivers I have posted in the Q&A section (these are the ones that are linked in Design Gears Odin 1 Click Back to Stock post btw) - but I would try and COMPLETELY removing the pre-existing drivers before installing the new ones.
Make sure the USB Cable is plugged into the back USB port that is directly on your motherboard - this will ensure it's not a computer/hardware related issue.
I know of one user who had to go through his computer and manually remove all remnants of other drivers. I have my phone connected to both a Windows XP 32bit and a Windows 764bit systems and have been lucky to not have any USB issues.
If none of that works - I'd suggest taking it to your nearest AT&T/Rodgers shop and see if they can get the phone to connect (make sure it's back to stock!). If not they should warranty replace the device.

This isn't my first rodeo... But to answer your questions:
I used the rooting method posted in XDA forums - the one-click rooting.
I've used the drivers included in the xda-forum. Not the kies software.
The only thing that changed was the loading of a new custom rom. The cable works (confirmed on my friend's phone). I can't get odin to restore back to stock because I can't get the computer to recognize the phone in either normal or in download mode. I've restored to stock using the jh7 in the stickied q&a thread
I don't think it's a hardware issue either - I think it's software-based. I'm going to try to take it to an at&t store today at lunch to see what they say.

I also have that problem only I noticed it when I cleared the dalvik cache. It messed up the auto rotate so it was always sideways and now I have no connectivity to the PC. Let me know how ATT treats you.

Potential (very annoying) USB connection issue

I went into menu -> settings -> connectivity, and set the USB connection to "Always Ask" when connecting to a computer so that it would ask me if I want to use Charging/Mass Storage/Media Sync/etc. Even with that box checked, no matter what I do, when I connect the phone to my computer, it does NOT ask me what USB connection mode to use. Can anyone else confirm whether or not they experience this problem?
Thanks!
SOLVED - driver conflict with my Samsung Epic. Connecting one then the other wreaks all sorts of havoc.

call Verizon or LG for that support..OR try your control panel windows settings..devices

Sounds dumb, i know...but it worked for me today when I had the same problem. And I think I recall it working on my old Incredible.

SOLVED
SOLVED - driver conflict with my Samsung Epic. Connecting one then the other wreaks all sorts of havoc, between mass storage mode and whatnot. When I switch the LG from charge to mass storage and back on the fly, it's doing something to the samsung drivers. When i reconnected my samsung, then the LG again, things went cuckoo for cocoa puffs until I rebooted.

I can't post a new topic as I have less then ten posts but I have an issue with my connectivity as well. When unplugged the phone still shows the USB icon in the top left corner like it is plugged in. However when plugged in the phone will charge but when connected to a computer mass storage mode will not work or show up. I have tried it in windows xp/ osx on my MacBook. Windows 7 on my desktop and nothing. The drivers are good as it was working before. I have done a wipe/data, restored back to cubed 1.1 mod and it is still doing it. It doesn't bug me that bad as I use andftp to move my apostle back and forth from my NAS to sdcard. But I would like it fixed as trying to put music or ISO's for my psx emulator can take a minute over the wifi. Any help would be appreciated.

Why am i getting a Factory data cable connected and i cannot switch between usb modes?

[Q] how to enter mass storage mode with PC seamlessly?

Hey guys, been trying to figure out how to connect my phone to my pc without having to have kies installed on every computer I access using the usb cable. After struggling for a while I figured out the problem was because I had usb debugging mode activated, and once I unchecked it abracadabra! I was able to access my memory card just like any regular flash disk. The only problem am experiencing now is that, even though I have usb debugging unchecked, every time I connect the usb cable it automatically becomes checked again. meaning I have to go through the long process of going to settings> applications> development, to uncheck it again. Why is this happening?

Install these samsung drivers and you will be able to do so.
http://hotfile.com/dl/109276666/f22355e/SAMSUNG_USB.rar.html

Dont quite get the problem.
When I plug in the USB cable to the phone and PC, the phone's task bar shows a small icon at the top. I pull down the task bar (or what ever it is called - it is pull down), touch the info about USB, and up comes a dialog box about enabling USB storage. I touch OK, and there is a warning about not being able to use apps on the USB. I touch OK again, and I am now connected to the PC.
First time or so, I was asked to turn off USB debugging, and never had to do it again.

Then maybe its an issue with my phone, originating from the factory, coz everytime I connect I am forced to go find the usb debugging option from way deep in settings coz nothing appears in the drop down task bar until I uncheck it. I am now getting paranoid considering the first time I bought it and took it home I found out that the standard micro sd card I was issued with did not work and had to go back to the store and get a replacement card. Maybe I should have opted for a different phone too. "cockroach theory"

Thanks for the drivers, but that was not the solution I was looking for exactly as that would mean I would have to install them on every computer I ever connect to, seeing as I prefer to double up my phone as a flash disk too coz its harder to loose and no pal would ever ask to use your phone to go borrow something (thats how flashdisks get lost) and I can also charge the phone when am copying new movies and songs, catch my drift.

If i recall correctly this also happened to me when i bought the phone. But after i installed samsung kies or the drivers it got ok. But as you say, if you use many computers its not pratical. I mainly use this one so no problem for me.

When you use your phone as a flash drive, you can expect to use it as a normal flash drive - simply plug it in, and the PC recognises a USB mass storage device. There ought to be no need for any drivers. Even on windows PCs.
But, you will have to unmount the SD card from within the phone.
If you need to disable USB debugging mode each time, try disabling USB debugging without the USB cables plugged in The phone ought to remember it. The menu option is, IIRC, settings > USB and media.
Things are slightly different in 2.2.2 froyo, 2.4.5, 2.4.6 and the current 7.1 CM custom kernel I am using. So, I cannot exactly remember the menu option. But, it is not a driver issue.
BTW, I installed the samsung USB drivers for Kies and ODIN from the phone on a newly installed OS, and was on stock 2.2.2 Froyo then so I am very sure that this is not a USB drivers issue.

My phone just updated to 2.3.6 and every time I plug the USB cable in, debugging mode automatically activates, even though I have unchecked it without USB cable plugged or after it was plugged. When I try to enter mass storage mode I get prompted that some apps might not work while in this mode. I tap OK and the phone tries to connect but after a while reverts back to debugging. That would not be a problem if I was at my home computer as running keys unlock the mass storage mode adn I can use Total commander to load what I want, but when at work, I do not have admin right so I can not install driver. Until yesterday I was on Froyo 2.2.1 and mass storage was no issue...

[Q] How to change USB connection mode?

How can i change USB connection mode for the Note? Everytime I connect the USB cable, Note always connect in MPT mode even with the MHL adapter. Help pleaseeeeeee

usb debugging
go to menu/settings/applications/development on phone then put a checked mark in the box for usb debugging. when you connect to your computer your phone will beep letting you know it has been connected to a usb source. use pull down screen touch the usb connected message and then touch the connect usb storage button. the little green guy turns orange and now your phone will show up on your computer as an extra drive. from here you can just drag and drop files to the phones directory just like a usb pen drive. i believe this is what you where asking about. hope it helps.
note: first time connecting your computer it will probably install a new device driver and also if you are using Kies you need to turn off debugging before Kies can see the phone.

First off, makes sure you install latest version of Samsung Kies, which includes USB driver for the Note.
Also there is setting to connect mass storage mode manually: Settings -> Wireless and network -> USB utilities. But it seems to be the same as just choosing to connect from the notification bar and wants you to disable debugging.

I am facing similar issue, Windows7-32 bit, when connect SGN via USB (MTP) for firmware upgrade but not sure about 'Kies Mode', few other people got firmware upgraded successfully so i think it's something else. see this link http://forum.xda-developers.com/showthread.php?t=1318734&page=59.

In the notifications bar at the top of your screen. You will see a usb symbol in that bar. 3) Use your finger and pull down the bar and then tap the usb symbol. There you will see the option to chang it from MTP mode to any other mode option it has.
I hope this helps.
