I am planning to buy nexus 7 (16 gb) but I live in a place where I can not always rely on cloud storage.
I was wondering if I can plug in USB pen drives using ITG cable and do data transfer (both way) on nexus 7 ? This works perfectly fine on my rooted galaxy nexus (using stick mount app) .
Please let me know if someone has tried this on nexus 7.
Thanks !
Lots of threads on this already. Yes, it has been tried and proven by hundreds, if not thousands of N7 users. It works exactly as it does on your rooted galaxy nexus with stickmount and an OTG-usb adapter. Works with thumbdrives, sd and microsd with a card reader, and some external usb hd's.

Hey,
Does anyone here have the USB adapter for their Samsung Tab 10.1? Can you connect a USB hub to it (maybe a powered USB hub)?
I take lots of full resolution photos, and would like to use the Tab to transfer data from SD card to portable USB hard drive.
What I want to avoid is having to first copy the SD card contents to the Tablet, then connect the tablet to the portable HD to unload the photos. That seems like unnecessary wear/tear on the flash memory.
If the USB host on the Tab 10.1 can handle a hub, then I can connect both the SD card and portable HD at the same time...hopefully the Tab would make use of it's RAM (the 1GB spec) to transfer chunks of data at a time, without resorting to using the internal Flash memory.
Am I right about that? The Android OS doesn't use the flash memory as a page file for working memory the way desktop computers do with drives?
bump - hoping someone can answer. Thanks.
There is a thread in development about a homemade usb adapter, and it works successfully with a hub. The samsung adapter isn't available yet, but should work the same

pokey9000 figured out how to force the unit in host mode. All you need to do is put 20ohms of resistance (easiest way with two 10Ohm resisters in series) between pins 13 and 15.
He also tested using a powered hub and was able to connect to multiple items at once. A regular hub might work for a few thing that are low powered but if you plan to have two hard drives, it better be powered.
has anyone found a usb to sd card adapter for multiple sd cards?
Did you ever figure this out? I want to do the same thing.
Hi people,
I read in a review that you can connect an external hard drive to the nexus 7 (the usb powered ones) via a USB Host Cable.
Could any of you tell me if this is correct or not? As i have an Archos 80 g9 and i know it cant do it off the micro usb only the USB 2.0 slot it has.
Thanks a lot for the help

Yes, it is possible but you may need to provide external power to the drive. Use a powered usb hub or something like that. The Nexus 7 most likely won't be able to output enough current to power a spinning drive.
Ah ok, so you are saying that you plug the usb host connection from the nexus to the usb hub and plug the hard drive in to another port on the hub?
I just want to know if this works as 16GB isnt much space when you want to take it on a trap to watch films.
cheers
you need to be rooted. my understanding is flash drives or micro sdcards are good to go, not sure an external hd will work unless powered as previous poster alluded

Since N7's have been out for a few days, has anyone tried hooking up a portable hdd using a micro otg cable? I could plug my portable Toshiba hdd into my Acer A500 tablet without rooting and it would read the contents of the drive just fine. I would watch movies and view pictures as if it were an sd card. Wondered if the N7 unrooted could do the same?

No it does not mount the external storage nor does it have an option to do so. You need to root and install chainfire's stickmount app for this to work.

Hi. I decided to use a wireless drive to store all of my music, movies and documents. So, I purchased the Seagate GoFlex Satellite Mobile Wireless Storage. You can use with Android or IOS devices. I love it.
Yes, its a no-go out-of-the box connecting to a USB thumb drive or a powered HD with a microUSB OTG cable. This doesn't really surprise me, though, because they would need to dynamically detect the device type and mount it on the system. What I haven't tried is a USB keyboard. Anybody do that?

yes could u test it out? i was thinking of buying a portable hard drive but not sure if it will have enough power to use it
does usb 3.0 work? or do i need to buy a usb 2.0
I've tested mine with an old 60GB WD Passport and a new 500GB Freecom XXS. Both are 2.5" USB powered external HDDs, and both worked fine.

great thanks for the info. btw is the new one using usb 3.0 or 2.0? do u know if usb 3.0 will work?
I just plugged in a full-sized USB keyboard using my OTG cable and it works fine. I can touch type, use the cursor keys including ctrl+arrows to skip words, bring up menus with the context menu key just to the left of the right-hand ctrl key, etc, etc. I'm sure it must be using up my battery at a faster rate, though.
Edit: It's just occurred to me that there's a problem with using a USB keyboard to type when the N7 is in portrait mode: finding a stand to hold the tablet upright at the right angle when the USB-OTG cable is sticking out of the USB port at the bottom of the tablet.
Mind you, it's great being able to type at full speed without a soft keyboard hiding a large chunk of the screen.

You can get OTG cables with a right angled micro-USB plug on them, which might help your stand problem. I have one on its way as I was concerned about knocking/bending/snapping the straight plug when its sat on my lap in portrait mode.

Or, just turn the tablet upside down so the cable is pointing up. The display will rotate appropriately.
I think but not sure that you'll want cm10 for the rotate from any angle thing...

how did you manage it ??did you use nexus media importer
Without a custom kernel, the external hdd won't work with Stickmount or NMI if it is formatted NTFS. I haven't actually used NMI, but others have posted about the NTFS issue.
I bought a 32gb SanDisk Cruzer Fit to store my music library on, and it worked initially with USBOTG and stickmount. However, it no longer works with Nexus 7, all other memory sticks are fine, and the SanDisk works on my PC, but not the Nexus 7. Anyway, I plugged it into a USB hub and it works again, but only through the USB hub. Anyone else noticed this kind of behavior? I'm guessing it's related to power draw, as the hub is mains powered, but I'm surprised it can't cope with a flash drive. I'm now wondering whether to buy another device, or whether the same thing will happen.
I had the something similar and a reboot fixed the issue for me. I tried plugging in my 250GB WD Passport but I guess there wasn't enough power for the external drive because it kinda just sat and clicked. I then tried plugging in my 16GB thumb drive that I know worked the day before but now matter what I did, I could not get it to mount through StickMount. I rebooted the Nexus7 and I was then able to use my thumb drive again. Not exactly the same but try a reboot if you haven't already.
I also have that problem with my Buffalo USB hard drive, where it sits and clicks, it's OK via the hub, but not direct. A reboot doesn't make any difference. I'm wondering if it's my USBOTG cable, as that's the only variable, I have read that others have got the SanDisk 32gb to work with the Nexus 7. I'll try another cable...
Got my new USBOTG cable, and the Sandisk 32gb now works. My external HDD still doesn't work (unless plugged into hub), but that's not too surprising. The new cable is this:-
Afunta(tm) USB 2.0 A Female to Micro B Male Adapter Cable (search on amazon.co.uk)
The old one works with most of my USB sticks, but is maybe not as solid in terms of build quality, as the new one is much tighter. The old cable is this:-
Brand New Micro USB Host Mode OTG Cable Flash Drive SD T-Flash Card Adapter FOR Samsung GT-i9100 i9100 Galaxy S II 2 GT-N7000 Galaxy Note (search on amazon.co.uk)
I have a 1TB Toshiba HD and can't create any files or folders on it with my 32GB N7 GSM, nor can I transfer any files to it. I can do it on a regular flash drive though. I am running Xenon HD with the Timur-USBhost kernel. I have tried both stick mount and Paragon NTFS to no avail as well as other kernels. I assume that the drive is too large. I can open the HD and view all my files and watch movies from it, but moving anything too and from it is not working. Any help?
Sooo... Anything?

You didn't mention you are using an OTG-usb adapter cable. That is required for external media. I use stickmount with my OTG-usb cable and have read/write access to my external memory devices except for my WD Passport 750Gb. I think it is because of the NTFS formatting on the hd. Other external drives formatted fat32 work.

Yes, I am using an OTG cable that I made myself. It seems implied that I am using one because the transfers and folder creations work with thumb drives. I will try formatting the drive in Fat32 and see what happens.

I plugged my Toshiba 1TB (cavalier plus or whatever you call it) into my Nexus 7 via a USB-OTG cable and was able to transfer and watch movies off it fine using StickMount (Because the rom's built in OTG capabilities don't support exFat). It worked but it was also sucking like 900-1.2A out of the N7's USB port
I have a theory though. Maybe it's NTFS formated and he doesn't have the appropriate read/write binaries placed, With stickmount you have to manually provide the binaries on /sdcard for the read/write support, where as most will just read it, but not write to it. And typically a 1TB isn't going to be formated with Fat32 so usually it's NTFS or exFat (but most thumbdrives will be fat32).

That you made yourself? I don't know the technical details of it, but there's more to an OTG cable I thought than just simply sticking the right plugs on both ends.
Dear god... If it works for flash drives it is obviously a correct cable. I am a small electronics engineer and have made more OTG cables and USB Jigs than I can count. I know what I am doing when it comes to making them. The only difference between an OTG cable for a Nexus 7 and just putting wires in stuff is to short out pin 4 (the ID pin) and pin 5 (the ground) together for a functional OTG cable for a Nexus 7. Other devices may not need that and then some other devices require a 100k ohm resistor in between the 2 pins. So... Again, it is obvious that my cable works if i can view stuff on the drive and use flash drives normally with creating and transferring files and folders. The only issue I have is not being able to create or transfer files and folders on the hard drive.

If you can read but not write, then it should be obvious you have a "permission" problem. Have you tried using Root Explorer and changing the folder from RO to RW?
It is set to RW.

So after completing my backup of my drive, I was able to use a format utility to get fat32. Works now. Take note: when using any format utility to convert a drive that is USB 3.0 to fat32, make sure it is plugged into a 2.0 port or it won't format it correctly.

So this wasn't always a problem, and I can't say when it happened, but it has begun to annoy me more recently.
OTG storage used to work. Something like six months ago my Galaxy S7 Edge (Android 8.0.0, Verizon, Developer Options Enabled) stopped recognizing when I plugged OTG storage devices into the phone.
The two USB thumb drives I primarily use are:
SanDisk, 128 GB Ultra Dual USB Drive (USB 3.0 / Micro USB), formatted ExFat32
--> This is not detected when directly plugged into the micro USB on the phone, nor when connected by USB OTG cable
SanDisk, 32GB Ultra Dual USB-C Drive (USB 3.1 / USB-C), formatted Fat32
--> This I can only connect with an OTG cable, not detected
Both of the drives work on Samsung Galaxy Tab S2 and Tab S4 (I got the Tab S4 for Christmas).
The only way I can easily get files onto the S7 Edge is by connecting it by USB to a laptop.
I don't see any settings that would turn on or off OTG Storage in the settings. I don't want to reformat the drives, I've tried that many times.
Does anyone have any suggestions as to what might be keeping them from being detected? I have the pro versions of ES File Explorer and Solid Explorer both on the phone.
Thanks,
Joe
Hey Joe, I realize this is almost a year old but did you ever find a solution? I've just formatted my DUAL USB (128GB) to exFAT and it is no longer recognized by my Galaxy S7 Edge. Any hints greatly appreciated. Cheers, Scott
I have not been able to get the S7 Edge to recognize external storage / USB togo memory. I gave up trying; transfer files directly from pc to the phone now. I assumed it was a software update that killed usb memory access, but never was able to confirm.
Sorry,
Joe
