[Q] micro usb to usb adapter

Here's a cross post from the Mesmerize thread where I'm not having any luck:
I have a 2.2.1 (rooted) Mesmerize and I can't get it to recognize anything plugged into the Samsung Micro USB to USB Adapter I just bought.
The phone is set to "Mass Storage" for USB and I've tried both USB Debugging on and off.
I can't get it to recognize any of 5 thumb drives that I've tried connecting to it. So either it's a bad cable, or something else in the phone is preventing the connection. Help, please!
EDIT: I'm possibly naive in assuming that this (reading a USB thumb drive from the phone) will work at all, but since they (Samsung) sell the cable and tout it as being capable of it, I must just be missing something such as a setting or the necessary version of Android or a wonderful hack from this group.

Please use the Q&A Forum for questions Thanks
Moving to Q&A

What you are asking for is a USB host function on your phone. As far as I know there is none for the Mesmerize or android. The cable is to connect your device with a pc or other that does have usb host drivers.
there are probably other, better ways of getting extended storage. what exactly are your trying to accomplish?

I just figured it would be cool to read off a thumb drive (or usb card reader set up as a thumb drive with an sd card or micro sd card attached) from my phone. For instance, if I'm out somewhere and I take a picture with my camera and I immediately want to get that picture from the camera to the phone (without using a pc as a bridge)... I could just remove the sd card from the camera, plug it into my card reader, plug my card reader into the micro usb to usb adapter and then plug that into the phone. Whereupon the phone would recognize a thumb drive is attached and let me navigate it the way I navigate the internal micro sd card.

yeah I don't think usb hosting was available until 3.1
I don't even know how easy it is with newer devices.

What about with a custom mod/ROM?

mad towner,
i would like to know how did u root ur phone. i have a tab with same os as yours. but i find it very difficult to root.
thanks in advance.

connecting external hard drive (transcend 25M3) to android phone ( micromax a116) ( )
Good news for everyone who want use external hard drive with android phone. I connected my Micromax A116 with transcend store jet 25M3 1TB external hard drive without rooting of phone. You have to possession of OTG cable only. Transcend hard drive one benefit that its having connecting cable with two USB male point . One for specifically power supply and other for data transfer. I used my Micromax phone charger having out put - DC 5V 1A with USB connected. first I have given power supply by connecting USB end of hard drive to the Micromax phone charger then I connected data transfer USB of hard drive to OTG cable then its micro USB end to my Micromax a 116. And its successfully access all the file and folder in hard drive. Plz Keep in mind that hard drive formatted in FAT32. Your phone should be supporting USB storage devices. And biggest thing is you don't require any rooting or additional apps for connecting. I think it will be very helpful for Micromax A 116 users . I can easily play HD video from my hard drive.

i have a noir A10 and i have connected an 80 gb hard drive via otg cable and an app installed on my phone i.e Stickmount.

So what am I doing wrong???
I have a Samsung Galaxy S4 and I wish to connect it to a USB hard drive. The one I'm using at the moment is an old 40gb drive but, if I can get bit to work, I intend to get a bigger one.
Sooo...
I've got a USB OTG lead.
I've connected the drive using a 'Y' lead to ensure that there is enough power for the hard drive.
I'm using ES3 File explorer.
I've connected USB sticks and cards also used USB hubs and Card readers with perfect results.
ES3 recognises the drive and asks for permission to access it but when I give permission it says "Sorry the operation failed". Trying again gives a different message "Failed to open the file".
I've tried reformatting the drive as NTFS, exFAT and even FAT32 but it makes no difference.
The drive works perfectly when connected to a number of other devices.
Any ideas?

[Q] usb hdd access with tab2 10.1

hi guys,
does anyone knows how to access a usb external hdd with galaxy tab2 10.1?
ı've bought OTG cable. I tired several things with OTG and Y-usb cable. but i couldnt manage to do it.
the error on tablet is "high power usb device connected"
does anyone connected a usb external hdd to galaxy tab2? what is the method? do i have to root?
thanks in advance.

I use an external hard drive to move files to my AT&T Tab 2. It is not rooted. The error you are getting is most likely the tab cannot power the external hard drive. If your hard drive does not have a separate power connection try connecting it through a powered hub. My drive has the y cable. One is for power and the other is for data connection. It works just fine. At home or work I connect the power to my pc or Tab charger and in my car I have powered USB.
Also the OTG does not support NTFS so you will have to use a 32GB or under drive or find some way to format it Fat32

Thank you for the answer.
i understand that OTG + Ycable + tab charger is the solution for me.
if i use fat32 500gb usb external hdd, is it ok?

I would assume yes since my drive is a HP 500GB pocket media drive.

[Q] Connecting External Hard Disc to Tab 2 7.0

Hey,
I yesterday bought a WD My Passport Ultra Portable 1TB External Hard Disc keeping in mind that I be able to connect it to my tab 2. After I got the HD I used my OTG Cable to connect my HD to the Tab ( I Already Formatted the HD to FAT32 ) and after connecting the OTG cable to Tab and HD the LED on my HD glows for a second and then Turns off. After the LED turns off my tab shows a message in the Notification bar Removed SD Card Something like that. Please Note that I am using WD MY PASSPORT ULTRA 2.5inch 1TB External hard drive, As it's says that it doesn't need an External power supply
Please Help me with your Suggestions how can I connect the HD to my tab?
Thanks in advance.. :good:

This happens because the tablet don`t provide enough power to the HDD, if you are on stock ROM, there should be a notification about "high power device" or something like that. I have the same issue with my HDD and 3G Dongle.
You can try with the battery fully charged or with a powered USB hub.

I don't think it's as much a power problem as Android doesn't support anything but fat32 natively. If you have an older win98 computer, you could fdisk it to fat32, and read the full 1 TB. but android will only write to a 32gb fat32 disk. An option would be connect the drive to a
windows xp or newer computer and use OBEX Commander on windows with bluetooth to move files to the Tab via bluetooth, but it's slow.

Mount two USB drive

Hi,
When I connect my one to hub with an OTG cable and put a usb hdd on it the harde drive is mounted and everything is perfect.
When I plug a second USB drive, it is not mounted.
I made the same experience on my Samsung Galaxy and it works fine, I see the two drives mounted on the phone.
Any idea to make it work ? Yours.

Is the hard drive sufficiently powered?

Hi,
Yes it is. The usb hub I use is powered with an external power source. The other point is that when I plug the disk alone, the phone mount it, but when I connect the flash drive, the phone try to do something, but at the end, onyl the first connected is online. If I connect the flash drive first, and then the hard drive, only the flash drive is mounted
