Since I don't have two galaxy's s2 I just wonder if you connect two by using USB and OTG will phone see SD card of other device (using debuging mode on other) and which card will see(internal, external or both). This should work probably for all devices with Android and function to see phone as external disk.
Thx for reply.

Odin works fine, but problems with usb drivers. can't display contents of external or internal sd cards on computer. tried uninstalling and reinstalling usb drivers
Did you mount your phone when you plug it in?
How are your setings?
- USB set to ask on connection
- USB debugging off
Hi,
I'd like to know if there is any way of selecting mass storage mode only for external sd_card. When I conect to a PC or any other device, if I select mass storage mode, both internal and external storage connects, but I would like to connect only external one (the sd_card itself). Is that possible?
Just for the record, I'm using CM9 now, but I haven't found this option on any of the roms I've tested.
Thank you.
Just remove the sdcard from microSD slot and insert it to card reader ._.

I'm sorry, maybe I didn't explained it correctly... Of course, this is a way to access the sdcard, and I know there are some other solutions, but it's not what I was asking. I don't want to remove the battery cover each time I want to access the sdcard. I don't want to wear with me a card reader always...
There are some cases in which I'd like to use this feature. For example, my car stereo has an USB port. In case I connect the SGS2, both storage units connects to the stereo, but it only detects one of them, in this case, the first one (internal Storage). This has 2 problems, the first one is that I use the external sdcard for music storage, and the second one is that some applications that stores data in the internal sdcard stops working.
I know there are many other ways of doing things (using a usb drive, removing sdcard...) but I just wanted to know if selecting only external storage was possible.
Thank you.
I`m interested into this too...
Phone forgets ringtones selection when they are stored on internal card after card disconnected from PC
Is there any way to mount only external SD card?
SII i9100
latest JellyBam
latest Siyah kernel
I've tested both CM v10.1 and ARHD v18.
Neither has a "plain USB storage mode" for the internal/external storage.
I mean, I would expect the phone to behave like a "usual" USB memory stick when plugged into my PC.
Instead I only get MTP and PTP modes which don't work well with my Linux boxes (my house has no windows at all!)
Any advice?

Theres currently no way to use the internal memory as a USB device since it uses the MTP protocol.
However you can use your external SD as a usb device using SGS3 Easy UMS. Check here http://forum.xda-developers.com/showthread.php?t=1711009
Search on Google, it's a design of jelly bean, decided by Google, to secure internal emmc and to be able to use dynamically all the internal space for data. Internal sdcard is in fact a folder in data folder virtually mounted as a device by android os. On the contrary before that internal sdcard was a separate partition.
That explain why it can't be mounted as usb mass storage, which is only possible with plain partitions.
There are ways to bypass it either with the above mentioned app, either with a tweaked kernel.
While I can understand the limitation for the internal storage, I don't really get the point with the external storage.
The limit just makes things harder: I could eject the uSD and push it into a reader...
By the way, which kernel supports USB storage mode for whatever storage?
I run cm 9 / cm 10.1 .
Thanks.
You can use Easy UMS to mount the external card in mass storage mode
Yes. But why needing an extra app when it is a built-in feature with other (cheaper) phones and ROM?
Why, if the recovery (PhilZ Touch 3) CAN DO IT?
This was my original question, though.
Any thoughts/ideas on the following would be welcome. I have got USB OTG working fine on my HTC flyer using an OTG cable and Y cable for external power with a USB pen drive.
However when I try to use the same set up with a USB SD Card reader, I get the message "USB device not supported - The USB device you have connected is not supported. Please unplug both the USB device and the dongle.
Any thoughts on why this is not supported or any fixes?
The card reader works fine with the same 4gb sd card (from camera) on windows PC.
Hi
I've been having problems with my USB mass storage mode. It turns on fine, and I can transfer whatever files I want, but after I'm done and I turn off the USB storage mode, the ROM crashes. I've ejected the phone and the SD card from the computer before switching off the USB storage, but it crashes still.
Is this a known issue or there's something wrong with my phone / me?
Mass storage is been buggy for all kexec based ROMs for Razrs.
I suggest use AirDroid.
