SD card reader?

Hey guys, is there an external card reader that would plug into the micro USB port on the captivate? I've been searching for a while but all I can find is micro SD to SD card adapters when I would like to import photos from a camera right into the phone
It would be a shame to have to just use micro SD cards to use the internal slot. Thanks!

I dont know of one that exists. But if youre trying to import your pictures you are going to be better off just inserting the micro sd into your phone and then copying all the image files to the phone. Its essentially the same process you would do if you had an external SD card reader except you actually have to put the SD card in the phone.

here u go.

I'm not sure that there is such a beast that would plug into the microUSB, and if there was, I'm not certain that the Captivate has the functionality/interface to read and copy from the microUSB Slot. I'm pretty sure you need the computer as a go-between if the microSD isn't in the phone itself.
I think your best bet is directly putting the microSD from the Camera into the Cappy or you'll have to upload them to the computer first, then to the phone. Sorry

I've always wanted something like that, its a great idea but such a thing doesn't exist. Closest thing would be to get the flash drive adapter with the microSD slot built in.

Yeah, that's not really possible. For one thing it's a jack, not a plug. For another, it would need to power the device attached to it while still being able to be powered from the same port for charging. For another, it would need to be able to configure as a device or a host which would really be hard. And another, it would need to have drivers for SD readers, FAT, NTFS, and all kinds of other things.

this would probably be you best bet

Wow. I stand corrected. That's a really flexible controller chip. They should have shown a backup battery being used as well in the pics too.

a kernel with USB HOST mode,
a USB OTG cable
a USB to micro USB cable
a USB card reader
a SD to microSD adapter.
and you can do exactly what you want....
but you will need a back pack to carry all your cables and adapters.

One step could be saved with this

But nobody sells it, and who wants to splice USB cables?

This one?
Like this one?

I'm looking for the same.

How about this?

This part is odd:
- With own browser and ES browser
- File system format: FAT32 (does not support NTFS)

in general for any phone or tablet
an external hardrive like 1 or 1.5TB with USB will be a dream, u can power the drive with extra USB. But what about powering device with the screen? I think it will run out of juice much faster in this kind of setup. Your thoughts?

From the research I have done, it requires an org cable, an USB y-cable for hooking up an external power, and a from with org support. The two cables can be found on Amazon for 2-5$. You could use any USB charger or for portability... get one of the battery packs with USB output. Portable, but it is a lot to carry around.
You can also use a powered USB hub in place of the y cable.

Swapping internal memory with microsd(card reader) using cable. Etc.

Hi again
I was also wondering if it's possible to swap internal memory with a microsd card connected via a micro to USB cable using a card reader or can it only be done with internal microsd slot ? And also a stupid question but thought to just ask. Is it possible to transfer videos or files from a microsd card (card reader)/flash drive to the galaxy note 2 using that same cable ? I don't currently own the note 2 but I will soon. I'm just waiting to see if a 32gb will become available by the end of this month. Thanks so much for all your help !

What you're looking for is an OTG (on the go) cable... It'll allow you to connect usb devices to the micro usb, including keyboards, mouse, hdd, and even usb drives. You'll need to be rooted in order to use one though.

No that's the cable I'm referring to when I say 'micro to USB' cable. I'm wondering if you can swap internal memory of the galaxy note 2 for a microsd card connected by that cable using a card reader (with the microsd in it) or can you only swap internal memory with the microsd card in the phone and also if files or videos can be transferred from the microsd or a flash drive using that cable to the galaxy note 2. Thanks !

Can't seem to use external hard drive on my Tab 3

Having trouble accessing external hard drive. I have a USB thumbdrive, formatted to FAT32, and the tab will not even detect it. I tried a external hard drive, it has its own power adapter, formatted to fat32, still can't see it. The USB and External Hard Drive works fine on my S3 and my Note 3. Is this a hardware limitation?

AFAIK yes, the ground pin is left out, so no hardware support plus kernel support is missing in standard ROMs as well. See this thread as well. Someone said you can build a special USB OTG cable with own power support, but I haven't tried for myself.

My S3 and 3 8.0 both detect my 16gb thumb drive using the Samsung dongle.
I will probably get a 32gb thumb drive today, and also test it.

[Q] Tried various Roms and Kernels USB/SD card still not recognised.

I have been trying to get my N7 2013 to mount a usb stick and SD card to no avail. All my sd cards and usb sticks are formatted as fat 32, different OTG cables and connectors have been tried and stickmount installed. I have tried various alternetives to stickmount with the same result. I can mount the same SD cards, USB sticks and OTG cables on various Roms and Kernels on my 2012 N7. I am wondering if there is a setting that I am overlooking. Has anyone with a similar problem tried a dual USB stick, micro and normal USB connectors, this would eliminate the OTG cable. All other functions of the N7 USB port are working. Any help would be appreciated.

You need an app for that. Try Nexus OTG file manager

Thanks for replying Gotham. I tried your suggestion and it didn't work, I have tried various USB OTG Apps with no success. I am able to connect keyboard and mouse I can also connect an old Huawei E160 modem and my N7 2013 reads the micro SD using Nexus Media Importer.
Thanks

It works or it doesn't work?

I had already tried various apps Stickmount, the one that you suggested and others none worked with my OTG cables and USB pen drives or with my micro SD card and my USB drive reader. As stated before, I tried an old Huawei E160 USB HSDPA stick modem and it worked using the same OTG cables that I had tried before. I found an old multi card reader and that was recognised by Stickmount and Nexus Media Importer.
This means that it depends on the card reader used or the USB sticks. The USB pen drives that I was using were both 32 GB Kingston DT Micro drives.
Once again thanks for answering, I have pressed the thanks button.

I've had no issues with my SanDisk dual USB stick on stock rom and kernel.

MicroSd Problem

Hi, i bought this Xiaomi TipeC Adaptor
and this MicroSd Reader, to combine them toghether with my OP3.
But they just don't work toghether.
Separately, everything is fine, Xiaomi Adaptor charge my phone, MicroSd are working fine with other adaptors or with Pc, the reader either is working fine with Pc or others smarphones.
Did i miss something?
Thanks

still one test to do, connecting one OP3 on a PC with that adapter and see if you can transfer some file with MTP.

Did you turn on OTG in the OP3 settings? If you did, try it with a different OTG device and report back

Yes man, i did, Otg it is on and it is working with a TypeC MicroSd Reader. Recognized instantly, can move files. Same MicroSd.
So, every single piece is working fine alone or in combo, just not working this combination, with XiaomiAdapter (TypeC to Micro Usb and MicroUsb MicroSd Reader) but i can't get why.
Maybe the Xiaomi adapter doesn't pass enought electricity to power the MicroUsb MicroSd Reader.
But I don't know how to "overvolt" the Otg Adapter in order to make it work.

Not sure why this occurs but I've had the same exact issue trying to use micro USB OTG adapters with a USB-A flash drive.
USB OTG just doesn't work unless you use a USB-C OTG adapter. Same thing happens in the Nexus 6P
