[Q] [Verizon] Disc Drive and External USB

---

Hi. I've searched but found no answer so here is my thread . So I am somewhat unhappy with how my Verizon GSIII is behaving. Since day 2 I learned I cannot connect this phone as a disc drive on WIndows or Linux. The only options I get when connected via USB to a computer are Media device (MTP) and Camera (PTP). My friend show me his ATT GSII last night. It connects as a disc drive (regular flash drive behavior).

When connecting an external HDD via USB Android should recognize that drive as a mass storage device. His ATT SIII did this, my Verizon SIII did not. I got the message in the notification area "USB Connect" followed by "USB Disconnected." Thankfully, I have no files I want to transfer onto my device as I'm coming from an HTC Incredible, but in the future I will want to browse my file system on my laptop.

Am I the only one here with these issues? I am not rooted.

Edit: I found an article which looks like I can browse the external SD Card but not hte internal memory. This is only for root users however. Enable USB Mass Storage for root.


If your Galaxy S3 connects as mass storage, post the carrier.

My S3 shows up as separate internal and external devices when I plug it into my USB port and is listed as SCH-I535 when ejecting. However my Nexus show up as an MTP device when ejecting. Both devices are rooted.

So there may be hope. I'm going to root today, well try to. Can you link me to the ROM you flashed so I have a higher possibility of achieving what I want?

Will every build ROM found in the developer section here get rid of the OEM functionality?

I have the same 2 options as you when connecting to a PC, but, when connected windows will pop the "browse for files" instantly and the 2 drives will be displayed under Computer, one for the internal SD and for the external.

This was like this from the first time i plugged the phone in, before root, same after.

It actually seems like we get to skip the step of "Enable USB sharing" which I find great, plug in and the drives pop.

I used root66 to do mine.

However I had access to both drives prior to doing the root update.

Both of you seem to have more luck than I'm having. When I plug it into Windows I had no way of browsing files. In (K)ubuntu when I plug it in a popup has an option to browse which takes me to 1 folder names 'USB PTP Class Camera' which I can get to the internal storage, but not the SD Card. I'll be making a trip to Verizon today for sure. It makes me wonder if a rooted stock image from Samsung would fix the issue.

Quick question.

Which drivers did you install?

Why do I need drivers, I'm not doing anything but reading the flash memory? It should just work in both Linux and Windows.

Note that the guide to enable UMS on the S3 is for the International version, not the US version. The US version doesn't yet have a UMS option.

You shouldn't (and don't) need drivers for the SD storage to show up on your computer.

Just to test it I connected my S3 to my gf's laptop running W7, both drives popped right away there too.
