Thanks for trying all of this! I was just wondering if that problem might be because of insufficient power. Could you try plugging the stick into a powered hub and then into the Nexus 7? If that worked fine, then we know we've got a hardware issue. If nothing changes, then (hopefully) it can be fixed in software.

[Nexus 7 General] rmm200:
Sounds like an fstab type problem to me.

The files are not getting mounted where the app expects to find them -

or the file system type is different than expected. Fat32 instead of ext4 maybe.

Also - I would expect the storage to show up in /media maybe.

The Nexus 7 *is* google's Kindle Fire 2

I think I understand this all now. The Nexus 7 is not just intended to compete with low cost tablets like the Kindle Fire, it is intended to compete with just the Kindle Fire. It is a much more specific device than almost all of us have been imagining. That is why there has been such a disconnect with reviewer after reviewer saying "Of course it has MHL (and full USB-OTG)" while google has been saying nothing about such concerns. The customers going for the Kindle Fire don't ask such questions, in large part. Google was never even thinking about this.

The Nexus 7 is a much better device than the Kindle Fire. Anyone who has kindle books can get the Nexus 7 and install the Kindle app and they lose nothing in the transition. Synch your books when you are near a WiFi point, and you're done. And those customers will be brought back into the Google Play fold and out of amazon's own attempt at making a walled garden.

The Nexus 7 is much more of a poke in the eye of Amazon than it is anything about serving the customers.

The unfortunate thing is what is happening to the Nexus brand. Up to now, for me, "Nexus" meant hacker-friendly, near top-of-the-line, and open. But the Nexus 7 is itself much more of a walled garden type of device. Google doesn't even want us to be able to access external storage! How open is that?

This "redefinition" of the Nexus brand is beginning to make sense. Google wants to be the nexus. It wants to be the new Apple where we all use its services, not our own media files, storage, etc. We are just rouges in a battle of walled gardens.

So, if my take on this is correct, Nexus is the opposite of hacker-friendly now. For those of us wanting open, flexible, user-controlled devices, going with the non-Nexus ASUS and acer, etc. devices, those with near-vanilla android, is going to replace Nexus. What an inversion this has become.

Of course the Nexus 7 is going to lower the pricing across the board. So for me, this is the function of the Nexus 7. I will be warning my friends about it, though, in the same way I warned them before about buying into Apple's walled garden.
[Nexus 7 General] rmm200:
Can you provide a link to a - single - reviewer who has said "Of course it has MHL (and full USB-OTG)"?

I have pretty much read them all, and I have not seen that.
[Nexus 7 General] shonangreg:
I don't see it now, but in one of the comments sections of one of the reviews. The author was chatting with me and said it was obvious that is would support MHL or that it would be unbelieveable if it didn't support MHL.

Oh, found it:

http://androidcommunity.com/google-nexus-7-and-jelly-bean-initial-review-20120628/

"I didn't bring an MHL adapter with me mang.. but I'm almost certain it does. Would be lame not to have that. Sorry we just got them tonight"

...

"Most phones have it lately, it's almost the new standard so I can't imagine it doesn't. Sadly still haven't figured it out"

Addendum. The specific instances are not so important here, I think. It is apparent to me that many of us assumed this would have what has become standard, android tablet features.

Just imagine the conversation between google and ASUS four months ago:

G: Hey, ASUS, you know that cool little $250 tablet you're looking to sell two million of? How about you let us strip it down to our own version of the Kindle Fire, and we'll guarantee five million in the first nine months."

A: Oh, sure, but hey, you don't really need to strip it down. The hdmi out and the micro-SD are already in the design.

G: Yeah, sure. We know. But this is something of a stealth project. We want to grow our own little walled garden, and those features are just openings in the wall. Oh, and by the way, we want you to strip out the storage mounting of USB-OTG.

A: What? That won't save you a dime.

G: Yeah, we know, but taking it out just adds another brick in our wall.

A: Here at ASUS, we've been trying to remove walls. We're taking a risk, embracing the open model android represents.

G: Yeah, well, ours is a good wall, though, not like Apple's or amazon's stinky walls. Don't worry. The customers will like the benefits of our benevolent control ;-)

A: Oh, um, how much are you going to pay us? And can we make the "Nexus" logo much bigger than the ASUS one? We'll be a little embarrassed to affix our brand onto such a crippled piece of gear.

G: Deal. Let the crippling begin!
[Nexus 7 General] RMXO:
I'll do some testing with a powered hub & I will also do some MHL testing since I was able to find my Samsung & generic MHL from Expansys USA later on the day.

With the powered hub, I'll do testing with a FAT32, NTFS, EXT3 & EXT4 formated sdcard.
[Nexus 7 General] revmra:
Awesome! Thanks for jumping through all of these hoops for us. Reading these threads keeps me occupied until my 16G comes in the mail. :)

Part of me hopes that everything fails with a powered hub the same way as it did before. I'd prefer not to find out that the port doesn't provide enough juice.
[Nexus 7 General] cashmundy:
Right. Harder to monetize you if you're not entirely in their cloud. Local storage conflicts with their business model.
[Nexus 7 General] RMXO:
Here are current results of my powered hub testing. Sorry, been busy & it's going slow . Hopefully done by tomorrow.

[Nexus 7 General] rmm200:
Thanks for all your work!

Most important information to me will be how to copy arbitrary files to and from external storage.

If we can just get the data in and out - we can use it...
[Nexus 7 General] RMXO:
You're welcome & I used Root Explorer

EDIT:

Able to play video's, MP3 & read text/PDFs on EXT3 after transferring files from tablet to sdcard
[Nexus 7 General] digriz:
Any luck without uisng a powered hub?
[Nexus 7 General] RMXO:
Did you not see post 121? Use the link to see current testing results.
[Nexus 7 General] rmm200:
OK RMXO - now you have confused me.

Are you saying that you can play movies, etc. from external storage, if you first transfer them from the tablet?

If I have that correct, that might be a security problem. Google likes to encrypt

pretty much everything now. I have seen similar problems with the emulator, where you have to delete a security file.
[Nexus 7 General] RMXO:
Yes, I'm saying you can play videos on EXT3 & EXT4 after transferring files from the tablet to the sdcard via OTG with a powered hub. I need to redo testing via EXT 3 & EXT4 from an OTG cable only. Unable to play files from FAT32 even though I moved the files from the tablet to the sdcard.

I originally tested EXT 3 & EXT4 for RW access but not video & music playing and reading of text & PDF's when I first got the device.

Yes, my results are chaotic & confusing since I'm only writing down my results with some comments in the "thoughts during testing". I'll probably have to redo my thoughts once I get done with testing.
[Nexus 7 General] rmm200:
Just to keep you filled up with test cases - although you may have already done these:

Format the external storage ext3 and ext4

Use Linux to transfer music and a video to each

See if those will ply from the tablet.

Hope you are keeping a spreadsheet...
[Nexus 7 General] ejkeebler:
At this point

does anyone know at this point if playing from external flash drive via otg not working is a limitation of software or hardware?

Also how long does it take to transfer about 1GB over OTG? if it's like 10 minutes, not sure i'll even bother, my son's attention span is certainly not long enough to wait 10 minutes to watch one of his movies....bit of a bummer it can't stream, oh well....still getting it :)
[Nexus 7 General] rferrett:
So, assuming I have understood this right as things currently stand a NX7 rooted can transfer files from a stick via USB2GO but not yet play/read media directly off a syick?

Or have I misunderstood?
[Nexus 7 General] BoloMKXXVIII:
Add to that the same type of keyboard/cover showed with the MS Surface and you are right!
[Nexus 7 General] rferrett:
Has the voltage of the port been firmly established yet?
[Nexus 7 General] MWBehr:
Yes he did that test.
[Nexus 7 General] rushless:
If the issue is as simple as the Gnex, seems people would be having success now with playing files from external storage without power.

My lame guess is the lack of support is by design and the level of hoops needed to jump to make it work would support the lame guess.
[Nexus 7 General] Nospin:
Well a large majority of people who would work on this problem don't even have the device yet. So I'm not quite ready to throw in the towel, give it at least a couple days after release.

I don't believe any lack of hardware support was intentional. Google had a firm vision of what they wanted, and had to cut a lot of corners to get there. They didn't go "And we won't put enough power to the micro usb...so they will have to use the Play store for everything! Muahahaha." If this thing had 32Gb for $250, none of this would be an issue.
[Nexus 7 General] rferrett:
So it definitely doesn't have the required power then?
[Nexus 7 General] rushless:
Fair perspective, but if the power is an issue, kind of trumps a lot of effort. Kudos not being cynical like me.

No doubt more users will increase any chance of success.
[Nexus 7 General] rferrett:
So is there anything from the iFixit tear down that would allow us to extrapolate if the port have 5v or not? Or is that something we will only be able to determine when Dev's start getting them "in the wild" like?
[Nexus 7 General] blaine.hale:
Just my scenario:

I bought this tablet with the plans of using it purely for mobile gaming (7 inches is great for it.) I plan on just running n64, snes, and psx emulators. So rom storage becomes an issue, right? Nah, not so much. I'm not a greedy idiot. Snes games don't take up much space so I can put tons on there and play whatever on a whim. Now, with psx and n64 I need to be a little more crafty. The games that I'm currently focused on, I'll store locally. The games that I may want to play in the future will be up on my drop box. I got 25 or so gigs free with my HTC one x, so that helps me but not everyone has it. All my music is on google play and I'm sure I'll have a few albums stored locally...or just, you know, use that other device I have (A PHONE!!) for that.
[Nexus 7 General] Cor-master:
Do you guys not have cell phones with SD slots or something? Every time I actually use my flyer I'm in a wifi zone where I can use the cloud for Google music. For stuff I need on the go, my HTC vivid with 16 gigs internal, and my 32

gig SD card works great.
[Nexus 7 General] shonangreg:
I wish you guys would quit saying you don't need the storage and video links so why should anyone else.

I do have a phone with MHL and a 16GB microSD, but I like to use my phone as a phone. If it is connected to a big screen to show a video, then I can't casually check email or answer a call.

All the "It's fine for me posts" are just silly.

The Nexus 7 is google's direct competitor for the Kindle Fire. It is a better Kindle Fire. That is all. it is not a general-use tablet, or it would not have been crippled by removing USB storage mounting (and MHL, imo).
[Nexus 7 General] rferrett:
So basically your argument is "I dont need lots of space so no one does quit whining"?

Jeez, bought shares in yourself much? Different people have different uses. I travel a lot and often spend ages away from home and primary reason I want a portable tablet is to consume media and stuff when away from home and wifi for large spells.

I don't know how ubiquitous super fast mobile data and genuine AYCE is wherever you are from but here in Britain there are loads of places where this isn't practical. Particularly our train network I have to use all the time.

I, like lots of people, would dearly love a NX7 if I knew there was a storage option that worked for me. Not necessary for you? Great, happy for you I really am. But don't imagine that because your usage patter is set in a particular way it goes for the rest of us.

</rant>
[Nexus 7 General] Cor-master:
its a budget tablet Get a premium one. Problem solved
[Nexus 7 General] rferrett:
Not wanting to come across as overtly curmudgeonly or anything but if storage isn't an issue for people why bother posting in this thread? Just buy your NX7 and enjoy! I would.

We all have different things that are important to us when we buy tech. For those of us who really like the look of the NX7 but storage is an issue a thread discussing they likelehood of a workaround seems pretty fair dos to me.

And I can't see why it is a problem for people who don't care? I just don't geddit.
[Nexus 7 General] TidBit:
LOL, this is just dumb.

You can use Airdroid to wirelessly send things to a tablet.

The only reason I see for people b!tching about this is to STEAL apps, by sideloading APKs.

You don't have to use Google Play. You can still load your videos by other means. But you can't easily steal apps or secretly load porn either.
[Nexus 7 General] pupsin:
Question:

Does a powered hub have to be used to connect a USB drive to the USB OTG adapter?
[Nexus 7 General] strikerage:
uh..... I don't steal any of my apps. I currently have an HP Touchpad that I setup to run CM9 ICS Nightlies. I switch frequently from Classicnerd, CM9, OaT, and Eyeballer's ROMs, and I make backups constantly so I don't have to worry about one release jacking up the TP, and I hate to delete too many backups just in case I need them for something else.

I have the 32 gb version of the TP. I have only 7gb left as of right now. Thats 7gb without any games, movies, songs, videos, photos, STOLEN APPS, PORN, or whatever you think I seem to need lots of storage for.

Not everyone has the need for lots of storage, but honestly, if you don't require much storage at all, then you must have a bomb setup for wireless data on the go, or shell out $100+ a month on home wireless service so you don't need to store so much on your tablet device locally. Good on ya for that.

I share my Sprint 4G (horrible 4g btw, and I'm directly under a flippin tower!) throughout my home on all devices (free, naturally since I use custom ROMS). My internet sucks for constant streaming, or using cloud storage services at home or on the go, especially since my phone will die within an hour of 4G hotspot usage after being off the charger, even after a full charge.

It is simply unacceptable for Google, or any manufacturer to produce a state-of-the-art device without including something as simple as a microsd card slot. The vast majority of users obviously don't need one, but it's such an easy thing to add, and so obviously, purposefully, omitted, that it's a shame they won't get as many sales as they would have if they included one. Maybe only a 1% sales difference overall, but isn't sales in any manner better than less than what their full potential sales would be?

I love my TP, and even though I'd love to have a 7 inch tablet, I think I can wait for a Note 2 to come out and possibly pass on a 7 inch tablet since Google, Asus, Apple, and every other manufacturer seems to be hindering innovation to support quicker, more immediate results for their coffers..... I mean, if Google Play isn't making you enough money yet, don't you think you should make it more compelling to utilize instead of forcing the consumer to only have Google Play as the option? As a consumer, I can always just NOT buy your product, which is exactly what I plan to do.

Just sayin.... I can easily drop $250 on a device. Google just needs to make a device worth dropping $250 on. They want my money, then they shouldn't skimp on features. Why should we have to settle for less?

....whew! My knees are locking up. Let me get off my soapbox. ;)
[Nexus 7 General] RMXO:
Depends on the drive. SDcard adapters & flash drives don't need a powered hub but USB hard drives might. I would just plug it in & find out. I don't have any USB hard drives & too lazy to go to Fry's to buy one to test.

[Nexus 7 General] Psipherious:
Can you show us an alternative premium 7 inch quad core tablet with a 1280x800 screen that has SD and HDMI ?

I'd be plenty happy to pay an extra $100 for those two additional functions even though they're not worth even close to $100 extra.

Even the upcoming Acer A110 apparently only has a 1024x600 screen. It's a shame really... I know of no good alternative 7 inch device.

If only Google would release a Nexus 7 Plus with SD and HDMI ($299), would be the perfect tablet.
[Nexus 7 General] haloimplant:
I'm thinking the easiest way to get more storage might be wifi direct to an android phone with large capacity and/or an SD slot. My SGS has 16GB + 16GB microSD being able to access that would be good enough for me. No need for an extra device that needs to be charged. (Also if the phone has MHL, like an SGS 2 or 3, then who cares if the tablet has it?)

Does anyone know if files can be opened/played over wifi direct or do they need to be copied? Does wifi direct burn about the same battery as just using wifi or suck up more?
[Nexus 7 General] gbroon:
Posted this in another thread but I'm just going to use https://play.google.com/store/apps/details?id=com.dooblou.WiFiFileExplorer&feature=related_apps

While tethered on my phone I can browse files via the wifi. Wireless access to the sd card on my razr effectively gives wireless storage without any extra equipment.

I've only tested it so far streaming music to my tablet but seems to work well.

Free version works, pro version is only £0.59. Much cheaper than wireless hard drives.

edit halo implant posted while typing this.

not sure about effect on battery but if you are tethered anyway it shouldn't make too much of a difference

TBH that thing looks bulkier than the usb flash drive I just got...

Indeed but we know tethering does not go easy on the battery, I was wondering if just wifi direct without activating portable hotspot would be any more efficient.

[Nexus 7 General] Nattawat:
I've tried my Nexus 7 with USB-OTG cable connected with an external hdd, and it worked! Well, partly...

I can see the files in my hdd, but cannot open it right away. I can, however, copy the file from hdd onto Nexus 7 and open the file from there. So it would work fine for small files but not for things like HD movies, which is my main purpose of connecting external hdd in the first place.

Would be great if there's a way to open these files off from the hdd without having to copy over though.
[Nexus 7 General] torontobc:
Where can I buy USB-OTG cable?
[Nexus 7 General] Outrager:
The Nexus 7 manual on the Play store shows you how to connect Keyboard and Mouse already.

Were you using a thumb drive/memory card or an external 2.5" HDD? If it was a 2.5" HDD, was the Nexus 7 able to power it without an external power source?

I bought mine off eBay (just search USB OTG) or any place like Amazon.com has them too. If you don't mind waiting, the ones from China/HongKong are cheaper but can take 2-3 weeks or more to arrive and if there's something wrong with it they might give you a refund, but then you waited all that time for nothing.
[Nexus 7 General] Nattawat:
I'm using an external 2.5" HDD (Western Digital, 1TB) to connect to Nexus 7, and without using any external power source. Plugging it in the same way I did with USB flash drive.

The Rom you have installed would need to support the framework, check the rom's op to see if it states wether its incorporated or not
