Hardware confirmed via USB device info:
Tegra EHCI host controller
/sys/bus/usb/devices/usb1
control panel has both SD card and USB storage section
nabi changed from micro USB to proprietary.
It looks like an overgrown micro USB.
root needed to access?
I kind of like the usb now . just pop the end in to a usb port and it charges and u can get to the sdcards at the same time with 1 cable .
the same cable is on the nabi jr

Hi there,
I was wondering if Android devices had their linux kernel built with USB Mass storage support enabled.
What I mean is I would like to connect an external hard drive to my Samsung Galaxy S, mount it from a root console and see its contents from the phone.
I've seen there are very cheap USB adapters on the market (type A female - micro USB type B male should do the job).
Would that be feasible?
Thanks.
To connect any slave device to your phone you need to have Host USB support. As far as I know Galaxy S doesn't have this and can work only as "slave device".
If I purchase a female to female adapter and plug a device (such as usb memory stick) into the cable will the transfomer recognize it and be able to mount it as a disk ?
How about other devices such as keyboard ?

Hi!
I've rooted my Ace2 and tried to get USB OTG to work in order to connect external storage and to use DSLR Dashboard. USB Host diagnostics gives the following information (s. attachment). Neither external storage nor DSLR dashboard works. Is there a way to activate USB-OTG by editing config files? In that post I've read that the /etc/volt.fstab hat some lines commented out related to USB OTG.
EDIT: Replaced wrong screenshots
Any ideas? Wrong forum? Any suggestions?
You are using a specifically OTG cable to connect?
The cable must ground the ID pin on the USB connector of your ACE 2.
Many devices will work correctly (and automatically) when they receive the interrupt from the grounding.
See if you can get a USB keyboard to work first.
I used this (Amazon de Product B0068CEUAA) USB OTG cable.
I am not sure but in another post on xda I read that one need a new kernel where usb otg support is compiled in. I checked dmesg while connecting an usb drive, nothing happens there.
Has anyone with any USB OTG cable got this function to work on the Ace 2 (GT-I8160)?
i wanted to know if it was possible to connect an external hard drive to an android phone with usb on the go support using a female to female usb adapter something like this > http://www.amazon.com/SANOXY-USB-Gender-Changer-Female/dp/B000BSN4UY/ref=pd_bxgy_e_img_y

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?

Hi All,
I have seen many posts regarding using external HDDs asking which ones work and which ones don’t. So I thought I would share my experience which I think (hope) would cover most situations and answer most questions.
This is what I used:
1. 1TB 3.5”external HDD USB 2.0 with its own power supply (like mostly all 3.5”external drives need their own power supply)
2. 500GB 2.5”Seagate Caviar Blue external USB 2.0 HDD. Runs fine on a standard PC/laptop USB port without any extra power supply
3. 128GB 2.5”Crucial SSD in an external USB 3.0 HDD enclosure. Runs fine on a standard PC/laptop USB port without any extra power supply.
4. 256 GB 1.8”Samsung S1 external HDD USB 2.0. Runs fine on a standard PC/laptop USB port without any extra power supply. A 1.8”HDD is often used in a HDD MP3 player like the classic IPod.
I have used the above using the original Samsung Note 10.1 USB Connector kit, so I can’t make comments regarding other connector kits.
I also use the Paragon NTFS&HFS+ app from the Google Play Store to be able to mount the HDD which were all formatted in NTFS. Without this app I could not mount the HDDs.
My Results:
1. The 1TB 3.5”external HDD connected directly to the USB adaptor and runs fine using its own power supply.
2. The 500GB 2.5”Seagate Caviar Blue external HDD connected directly to the USB adapter did not work. The Note 10.1 produced the error “High powered device”. However when connected via a powered USB hub (i.e. with extra external power supply), then this HDD worked fine.
3. The 128GB 2.5”Crucial SSD in an external USB 3.0 HDD enclosure connected directly to the USB adapter did not work. The Note 10.1 produced the error “High powered device”. However when connected via a powered USB hub (i.e. with extra external power supply), then this HDD worked fine.
4. 256 GB 1.8”Samsung S1 external HDD USB 2.0 connected directly to the USB adapter did work. It appears these 1.8” HDDs are considered “low power” and it did work directly connected to the USB adapter. This also makes sense as these HDDs are used in many MP3 HDD players and could have a low power requirement.
Summary:
I have used 3.5” and 2.5” HDDs/SSDs with USB 2.0 and 3.0 interfaces, and I could get them all to work either directly or with an extra powered USB hub. Using a powered USB hub is a pain but at least it works.
Hope this helps in answering peoples questions whether it is possible to connect external HDDs.
Good stuff...thanks.
You need to use a USB splitter cable and connect the portable drives to an external power source. I do it all the time with my 750GB Seagate 2.5'" drive on the go. I have a portable battery with 2 USB sockets. The external battery provides power.
Besides, this has been discussed at length here and is no secret.
I'll stick to my wireless Seagate 500gb HDD... And when I have time to mod it, I'll make it either 1 or 2 TB....
