OTG Host works fine.

I currently have an OTG-USB Host adapter with an SD Card reader plugged in to it, I can read SD cards just fine. I also have a 4 port USB hub that I use to read my flash drives. So far my my portable hard drive does Not work. I will see if I can use it with external power on the hub. Another device would be the Patriot Guntlet it has WiFi-N, streams video, has a 5-8 hour battery life all for $99 (you supply the hard drive).
[Nexus 7 General] limpet:
SSD too

In addition to sd cards, solid state drives in usb housings work fine. The available power is is often insufficient to spin up a mechanical disk.

Nothing with read write access seems to work yet with Android 4.2, but I expect the problem will be solved before long. Don't upgrade if you need USB OTG capability now.
[Nexus 7 General] jsmith8858:
Here's a tip, not sure if anyone mentioned this idea yet:

Like lots of xda members, I tether my nexus 7 to my Android phone via WiFi for internet access. My phone (a GS2) has an external SD card slot and a 64gb card in there, giving me plenty of storage. Now, as long as we are tethered to the phone, you can also use an app like ES File Explorer on the phone to enable an FTP server. Make your SD card available via FTP, and use an app like ES Explorer on the Nexus to access the files over the phone's network that you are connected to while tethering. You can stream music and video this way and basically access your phone's entire external SD card this way, essentially expanding your storage a bit. It works great for me! Not ideal nor applicable in all cases, but it's pretty handy, even just to grab a file you need that's stored on your phone now and then.

Chainfire about to release new Stickmount with NTFS write capability on 4.2.1!

Just so you know, expect a 2.1.1 version on Google Play soon.:fingers-crossed:

Does that eat into you phone allowance if your using your phone I only get 500mb to use so I think that would be good unless it takes the data allowance.

It's possible nowadays to charge the battery of the nexus 7 and at the same time have plugged and working a 2,5'' HD?

Using this kind of adapters

https://dx.com/p/micro-usb-male-to-usb-female-w-usb-male-otg-cable-black-170927

What kernel is needed?

Taking into account that now you can easily install Ubuntu on the nexus 7 would be a good idea to use it as a server, seedbox,.... or whatever once It becomes obsolete.

Using OTG and Nexus 7

Bought my 32gb Nexus 7 last week.

I bought an OTG cable from Amazon and installed 'Nexus Media Importer' from Google Play.

I used it to download pics from my camera SD card. It worked fine.

Just tried connecting my 1 TB HDD, leaving the power adapter to supply power.

This also works fine and I have downloaded loads of my video files

View these with VLC. This also works a treat

Very happy.
[Nexus 7 General] mvmacd:
Yes it will work [assuming it's the correct cable, which I am pretty sure it is. As long as it functions as a normal OTG cable, with the addition of the Male USB for charging, it will work]

This kernel: http://mehrvarz.github.com/otg-power-nexus7.html

Here is a thread that has some discussion about the kernel: http://xdaforums.com/showthread.php?t=1934722

I searched this thread and lots more and still can't connect my nexus 7 with otg cable to internet.

Nexus is rooted, has 4.2.1 (stock rom) on it, OTG cable is this.

I tryed with PP widget app (set up APN and dialling string correctly), and StickMount apps and nothing. I'm trying to connect Huawei E3131A stick on 3g (Croatian network Bonbon - T-mobile)

Can you advise me somehow?
[Nexus 7 General] mvmacd:
Perhaps you can get a logcat after plugging in the 3g to see if it's being recognized? Not sure what else to say as I haven't had experience with 3g dongles.

External hard drive and 4.2

Prior to updating my ROM to 4.2 I was able to use various hard drives on my 7 including a 1 TB samsung drive. Now I get "Damaged USB Device" message. Stick Mount mounts the drive, but it shows empty. I have tried reformatting my hard drive in both NTFS and exfat with the same result.

My 16 GB usb stick is recognised and mounted okay.

I realise that I don't need vast capacity but whilst in hospital it is handy to be able to pull a couple of films or batch of music onto the internal SD,

I like 4.2 but may have to go back to 4.0 or 4.1 if there is no workaround for this problem.

It is not just a problem with the Nexus7 the same has happened with my Asus Transformer TF 101.

My Toshiba USB 3.0 portable 1TB hard drive works fine via USB OTG and nexus media importer app. My archos 605 media player with 40 gb hard disk works fine.

hahaha, Walmart Black Friday sale, am I right? :good: if so, I got one of those too [$59+ 6.25%tax]

Is this hard drive self powered? Or does it need an AC adapter?

I'm guessing the former, and possibly it needs more power to run than the N7 is putting out? That's all I can figure. Have you checked the logcat directly after plugging in the HDD to your otg cable?

I tried to delete a video from sdcard with stickmount.. It showed that it deleted it but it did not show more free space... I was trying to move another video from my laptop to my sdcard.. So i deleted another one and had the exact same freespace available.. Plugged sdcard to computer and the freespace that it showed was propper..

Can anyone tell me why is this happening? Thx
[Nexus 7 General] Milamber33:
Might be worth asking over in the Stickmount thread, but my first guess is it just hasn't updated the stored value yet. I bet if you forced the media scanner to run on the drive it would update everything properly.

Which file browser were you using to delete the files? I don't know much about how everything ties together, but I suspect it would be the file browser's job to make all the updates when a file gets deleted. Maybe it's not sending all the right messages?
[Nexus 7 General] Cubanluke88:
A lot of you seem confused as to why there is no sd card slot. Its not because adding one would be more expensive. Its not because it wouldn't fit. Its not because the motherboard doesn't support it.

Its because of the Play Store.

Notice how we can now buy movies/tv shows (as well as rent). Notice how we can buy music. Notice how we can buy books and magazine subscirptions. All from the Google Play Store.

They don't want you to have a lot of local storage because they know if you do, you can simply side load all of your media. Its not about getting people to use the cloud, directly anyway. Its about getting people to buy media from Google.

Amazon did the same thing with the Kindle Fire (8GB model and a ton of media through the amazon cloud store; no sdcard slot. B&N tried to do something similar, albeit by locking down the internal storage (they are pretty dumb, honestly).

No micro sd card slot makes a lot of sense when you look at the full picture and the future that Google is trying to carve out.

With that said, the custom rom I have on my Xoom allows USB OTG and I'm pretty sure the galaxy nexus has it too. I'm sure someone will get it working on the Nexus 7 and while its not as elegant or easy as a micro sd card, it will do just fine when you need it.
[Nexus 7 General] Nospin:
You are completely right, the Nexus 7 and Nexus Q are really just windows into Google Play. It is a smart move by Google, as the app store is where they really trail Apple. We all hate this move, but if we ever want a Nexus device I feel like we will have to get used to no micro sd.
[Nexus 7 General] Devilsduck:
Cloud! It's the future... Embrace it, use your phone as a hot spot.

Granted, more space/sd would be perfect, but you can't have it all for such a cheap device!

[Nexus 7 General] the_f4b1:
Everyone here says that Google didn't put a SD-slot into the device because they want the people to use the cloud. But why doesn't the N7 offer a SIM-slot? Of course, when I'm at home, i won't have any issues but personally I want tot use this tablet when I'm on the go and I don't want to use my phone as a hotspot the whole time...

Even though I really like the price and also the looks and hardware of this tablet, this is the thing that bothers me most and lets me think about buying it twice...
[Nexus 7 General] RowanOak:
If it only has 3.3V it is still doable, but you have to use a powered USB hub to be able to plug in your devices.

Admittedly, lugging around a powered USB hub and being tethered to a wall socket does kind of negate the "portability" factor, but it is an option.
[Nexus 7 General] aaronpoweruser:

My wild predictions

1)

chipset Micro(sd) pins/lanes and even PCB traces / spot for a reader slot will be quickly located during tear downs. Guide will appear to open up your N7 and solder a microSD card directly to the PCB.

2)

some one will make a form fitting "bump" that provides a microsd card reader slot via the microusb OTG interface. Think of a small bump molded exactly around the corner of the bottom of the case for stability so it can't be snapped off.

Kickstater project anyone? :-)

3) this will spur development of some very easy to use wifi based client/sever phone / tablet apps to allow quick easy direct read and/or transfer of data form your phone (with microsd) to the tablet.

4) this will spur development of (more) easy to use wifi andorid app and PC based server software that allows direct read/ stream of data from a PC at home. (roll your own cloud).

5) some one will make a microusb to microusb OTG cable: people will plug there phone into their tablet via OTG usb cable with micro SD on both ends. With Phone set to media usb mode, tablet as OTG host. Voila! the phone is the usb stick for the tablet

:laugh:
[Nexus 7 General] thekillingtree:
i can see the need for what you want to do if you're not wanting to carry around a laptop on shoots, but why can't you just get a micro sd card reader and carry that around in your camera bag? surely you'd be able to plug the sd card into that and have it mount normally, right?

i hope this functionality will be there. i know you could do it with the touchpads w/cm9.

OTG

Just saw this review:

http://www.anandtech.com/show/6054/google-nexus-7-mini-review

If you scroll to the bottom, it says:

Update: I've had many emails and questions about whether USB-OTG (On The Go) is supported on the Nexus 7, and didn't touch on it when I originally hit publish becuause I wasn't entirely sure. I've now confirmed that USB-OTG is supported on the Nexus 7, and works on the current Android 4.1 non-final build that has been sampled. That's encouraging, and I'll test it myself when I get home and to my miniUSB OTG adapter.
[Nexus 7 General] Nospin:
Yeah, the only clear statement there is that it is supported in Android 4.1 (which we know). The first person to upload a youtube video of them opening files off their flash drive will be a bloody hero and my official favorite person.

[Nexus 7 General] SoonerLater:
I have owned a Seagate Satellite for... nearly a year, I guess. I only use it on long car rides with kids, but it works great. 500gb of storage, about 6 hours battery life (in my experience; Seagate claims 7). It works brilliantly. I did install the hacked firmware from www.hackseagatesatellite.com and consider it worth every penny. My three kids and my wife can all watch a different movie at the same time. If 500gb is not enough, lots of people are swapping the 500gb drive for a 1tb. It's just a little onboard Linux server and WIFI router all in one battery-powered box. If 6+ hours battery is not enough, some users are swapping the physical spinning 500gb drive for an SSD. Any 2.5" drive 9.5mm or thiner will fit in the case. Crucial has a 512gb SSD that's 9.5mm for only ~$400 :laugh: It consumes <65 mW when idle; 0.15 W when active. You could probably push battery life to 10 or more hours using an SSD. But I digress...

The Kensington Wi-Drive 64gb costs more ($185) than the 500gb Satellite ($168), but the 32gb Wi-Drive is cheaper ($86). Then again, if 32gb was enough for me, I'd probably use use a micro usb flash drive or a usb dongle.

Hit me back if you have any Satellite related questions. If I'm slow to respond, just PM me, as I'm not on here every day.

With the March 2012 update, Seagate Satellite can join an existing wifi network, so the main rationale for the $35 HackSeagate FW is obviated.

[Nexus 7 General] SoonerLater:
That's great news for anyone buying one now. If those features were in the stock firmware when I bought mine (I... think... um... nearly a year ago), I doubt that I would have paid $35 for hacked firmware. The hacked f/w still has features that go beyond stock (even current stock), but as far as features that I care about the new stock f/w is OK with me.

Thanks for the tip. I wasn't aware of the new stock f/w features until you tipped me off.

I'm surprised it's taking this long to get these geeky details out to the forums, google gave thousands of them away to technology and blog hacks days ago! ;)

All we really need to know is is the port pushing 5v? If so, then we're sitting pretty for the customs ROMs to unlock the full USB mass storage potential.

What I'm hoping for is that I can use a microUSB to USB adapter dongle and then put an SD reader on that dongle, and use the Nexus 7 to view photos. It would be a much nicer way to preview shots I take with my DSLR than just using the back screen of the camera, and also much more convenient than taking my laptop with me or simply waiting until I get back home to a computer to view the images.

Hey RMXO,

When did you run your video tests? I downloaded an updated version of MX Player Pro about 10 hours ago and in the changelog it mentioned adding support for JB. Also, the dev has released another updated version since then to fix additional crashes.

You may want to run your tests again, as it may work now ;)
[Nexus 7 General] RMXO:
I ran the test about 4ish hours ago, I'll download it again & test it out when I test documents, pics & whatnot. I got stupid & just soft-bricked my device but booted back into recovery & restoring my nandroid.

EDIT:

Here are the following results to new testing

built in text viewer gives me this error "Error opening file. It doesn't exist or cannot be read" when trying to view a word doc, pdfs (pron I had in pdf) & text files directly from the sdcard via OTG. I used OfficeSuite but it wasn't able to read from the sdcard via OTG.

Installed the latest MX player & still unable to play video from sdcard via OTG

Unable to view pictures from sdcard via OTG

Looking like you need to transfer your files to the device & access it from there

I slammed the kindle fire when they announced it last year for not having an SD slot and only 8gig of storage, but then I got my 16GB HTC flyer, and I had planned on buying a 32GB sd card for it when I got it, but never got around to it, and after discovering google music, I found I really didn't have much of a use for an SD card. I eventually put one in it just because flashing custom roms pretty much require it and I got sick of having to take my phone apart and yank out the SD card everytime I needed to flash something, but that was my only use for it. Its not a deal breaker for me at all now. But that being said I easily filled up my internal storage with games that require additonal data (SD card won't help you there either), so I'll probably get the 16GB model. I hope they give you more than 8GB to the user, because that's all my flyer gives me, and its not enough if your a gamer.

I'll be purchasing one soon enough.

My only criticism about that unit is that it's likely that you're powering both a hub and a card reader all the time whether even if you're just using the USB port.

Seems Google went out of their way to make the N7 a cloud hugger. Just think if Google did not use ASUS, since we would then have the version of this with micro sd, hdmi out and full OTG support. All for $50 more, if ASUS T370 preview held firm.
[Nexus 7 General] rmm200:
Never attribute to maliciousness what can be explained by incompetence.

Most likely, Google never anticipated the need for application access to external media.

What Google does do is make it really easy for us to root and modify Nexus devices,

so what is likely a configuration problem is easy to fix.

Now if you want to talk really active obstruction of the consumer base, we can bring up Barnes and Noble... I returned my Nook Tablet last Christmas without ever powering it on.
[Nexus 7 General] Michael_W_L:
I think you are correct. The Galaxy did not have a mass storage USB-OTG implementation either.

As the hardware clearly is there, either they will implement it natively in a update (5.0 perhaps?) or leave it up to manufacturers, as has been done for awhile now.

If you can copy off, then it should definitely be possible to get it to work with applications.

I think though that a dedicated solution, like stickmount except specifically made for the nexus 7 will be required. Unless MHL is actually supported in the hardware, it is most likely using a different chip to the galaxy nexus.

Of course I am simply making an assumption;
