Solved:Mass storage mode

I have the exact same problem.
If I unmount the external SD card before connecting the phone in "Kies" mode then I can access the "internal" SD storage.  I then have to transfer files around on the phone using Astro.  This is obviously an exceedingly crap solution, and I would love Samsung to fix it.

Same problem as you guys. My computer runs on Windows 7. My KIES has been updated. The only time my cpu detects the SGS is when I plug it in via KIES. KIES recognizes it easily and the cpu does too. A seperate browse file pop-up appears similar to when you are plugging a usb device. I completely disregard the KIES pop-up and go straight to the SGS storage pop-up to do file tranfers. Clicking the mass storage option on the SGS does nothing when plugged to the CPU. I hope the next firmware update fixes this.

You need to mount the USB device. In the pull down status menu on the phone, click on the USB mode and choose 'mount'. The device will then be visible in the file explorer in windows.

Hi guy,

I now can connect the kies from my laptop to the continuum.

Go to setting, select about phone, select either mass or kies storage (both work for me)

Plug the usb cable to the laptop or pc.

Then slide the top of the screen down (where is normally show Wi-Fi, bluetooth, silent and vibration) and now you will see ongoing on the screen which show USB connected.

Now press the "USB connected" and you will see the message and said "you have connected your phone to your computer via USB. Select "Mount" if you want to copy files between your comopyuter and your phone's SD card.",
press Mount.

Now you should be able to transfer file between the pc and continuum.

It works for both Kies and Mass Storage with internal and external SD card Mounted

I had exactly the same problem as you. Everyone was telling me to use the pull down menu and select 'USB connected' to choose mass storage/mount, the only problem was everytime I selected 'USB connected' all it did was close the pull down menu.  

I managed to solve this problem by going into Settings -> About Phone -> USB Settings

The following list loads:

Samsung Kies
Media player
Mass storage
PC internet
Ask on connection

For me Samsung Kies was checked by default, so everytime I connected by USB it was always trying to connect to Kies.

I changed this to Mass storage. Now when I connect by USB and use the pull down menu I get the option to mount/unmount the device and I can access the files on my PC like any other USB storage device.

I really wouldn't of expected to find the USB settings under 'about phone' I only stumbled accross them because I thought I might have out of date firmware!
