It should....but we really need somebody who got one from Google IO to test it first.

For what it's worth guys, the cords sell as low as $1.99, and you have 2 weeks to return something to Google Play (double check that). So if you are dying to preorder you can, you'll just have to eat the price of the cable and restocking fee.

You can get the same cables on eBay also. I've been using the same one I bought for my sgs2 a year ago. Best 3$ I ever spent, hooked up to a fast USB or usb-sd with a class 10 card is what I use. I have 32gb of storage running any of the real large games off it too. Grab that app "gl to sd" it works basically like hard link extensions on windows or Linux.
[Nexus 7 General] Outrager:
What a company says at CES is the target price isn't always the price it sells for. And if Asus does release the 370T at a later date for $250 you could still just say that prices have went down since the launch of the Nexus 7 which is how they got to that price point. We really will never know unless the business people decided to tell us.

1080p

I tried playing a 1080p movie from a USB however the video is not smooth and lags quite a lot, 720p is smooth with no lag, I then switched to a external HD and the lag on the 1080p movie was less laggy but not perfect does anyone have the same problem

[Nexus 7 General] peterk-1:
Having tried what you are asking and failed (the power was being fed back from a USB hub powered by the nexus charger) I looked at the OTG specification at usb.org. That spec shows that the device USB socket is a rectangular socket - it does accept the micro USB plug. I therefore don't think that the Nexus is a OTG device or if it is the support for the OTG extra "electronics" is not recognised by the currently available software.
[Nexus 7 General] nicatronTg:
The device is a USB host, you just need a converter cable and something to mount devices with. You can connect an OTG cable with a hub, then a mouse and keyboard and it'll work fine.

Charging will not work, though, because once the device is in OTG mode for another device, it can't run two at the same time.
[Nexus 7 General] peterk-1:
Please see P32 on in the battery charging final 1.1 pdf in the zip file at http://www.usb.org/developers/devclass_docs/batt_charging_1_1.zip where the use of an "accessory charger adapter" to charge and connect devices at the same time. If they are available is another matter
[Nexus 7 General] dazdaz:
Sorry if this has been asked. I have a USB-OTG cable (thanks to the poster), and a rooted nexus 7 running stickmount. I am unable to read files from a 32GB Transcend key formatted with the exfat filesystem.

Has anyone compiled the exfat kernel module, for 4.1.1 ? I m not sure that it's that easy... I am unable to read the filesystem :(
[Nexus 7 General] 1iam5mith:
sorry if this has been asked already, but do you think there will be an update to make the n7 support USB OTG flash drives without root access, as i have a n7 and would like to use a flash drive to transfer files too and from the device, but dont really want to root the devices, is there an update in the works or anyone working on a work around for this do you know? thanks :)
[Nexus 7 General] dilldoe:
doubt it. most devices have microsd slots so no need for usb otg, so don't think Google will update it just for the nexus
[Nexus 7 General] jh1521:
Maybe not what you expect to hear, but...

You can always format the key with another filesystem. Exfat is not absolutely required.
[Nexus 7 General] dazdaz:
exfat is a good choice of filesystems, if your files are over 4GB in size. fat32 has limitations which exfat work around. Let me know if you have any more questions or PM me. Thanks
[Nexus 7 General] jh1521:
However, between a good filesystem that is supported, and a better one that isn't, I would prefer the former. Besides, fat32 is hardly the only other choice.
[Nexus 7 General] rmm200:
Keep in mind, exFat is a Microsoft proprietary, patent pending, file system.

Like Apple, they are aggressive in enforcing their IP rights

If you want to use it, Microsoft will be happy to sell you a license.

I will continue to use ext4 where I can. I think patenting cross-platform standards - reeks.
[Nexus 7 General] AraDreamer:
Yeah, but most Android devices also have USB OTG built-in, too. So, there's no real telling. But no, google probably won't do it, which is why there's the nexus root toolkit and stickmount.

Accessory charger adapter

I found the following information somewhere else (can't remember where) relating to this same issue:

I'm pretty sure the ACA won't work. A friend of mine is on the USB standards committee, and he says only Nokia fully supported USB OTG. There is a lot of signalling needed to get ACA to work, so the Nexus 7 and Galaxy Nexus only support USB host.

On the Galaxy Nexus kernel, removing the complete body of method tuna_set_vbus_drive() in arch/arm/mach-omap2/board-tuna-connector.c will disable charging of OTG slave devices and will allow the OTG host itself to be charged. The battery icon will not be updated by this modification alone.

One disadvantage: in a real on-the-go situation, this kernel will not anymore power slave devices. One could fix this by allowing the user to switch between OTG host mode charge-out (default) vs. OTG host mode charge-in. Should be possible with the N7 as well.

Perhaps this is something that can be done here?
[Nexus 7 General] taitony:
Google want to promote Cloud business, so they just offer N7 as plateform.

Above works very well for me. Only thing I tried was watching HD movies. Is there an easy way to mount (maybe auto mount on plugin) a USB formatted to ext4? Stickmount only handles NTFS and FAT, which I'm sure is OK for most but I would prefer ext*

As a side note, so true.....
[Nexus 7 General] papatel:
From my perspective, the biggest problem with USB-OTG wrt to Nexus 7 is the inability to charge while a device is connected. This is critical for mounting a nexus 7 in the car... I've read through nearly this entire thread hoping that someone had at least a partial solution. Looks like nothing yet.

As several of you mentioned, we need the kernel/driver modifications to allow us to enable charging while we have a device connected in host mode. Hopefully an expert around here gets to that sooner rather than later. It is most certainly possible. The first person who gets that working will definitely get a donation from me.

For now, I'm using a WIFI NAS (usb drive zip tied to a ddwrt router) installed behind the dash with a CIFS capable kernel from faux123 and getting to my 500gb that way... seems surprisingly reliable! I can power cycle the NAS while playing something from the drive and the nexus deals with it pretty gracefully (much better than my win7 box ;). I'm pretty sure using stickmount with a direct USB-OTG connection will be much better and I won't have to wait 40 seconds every time I start my car for my NAS to startup...

Is your portable drive NTFS or FAT?
[Nexus 7 General] JaSauders:
Whoa, it does? I thought for sure I heard some people say that they tested EXT3/4 and it worked. I was beating myself up because I cannot get EXT3 or EXT4 to work on my N7. It says it's connected, mounts fine, but each time ES File Explorer, Astro, you name it cite it as an empty directory when it's not. If I redo the process but with FAT32, it works fine. Thing is, I like utilizing EXT file systems since I really only utilize Linux. If I need to use FAT32, like you said, I will... but that's kind of a bummer if it's only limited to MS based file systems, especially considering it's... well... Android. :(

[Nexus 7 General] JaSauders:
Can any of you guys comment what file system you're using on your USB devices? That's what I'm most curious about...
[Nexus 7 General] iElvis:
FAT32 seems to be the most compatible across the board, though you're stuck with the 4GB limit.

All my flash drive worked out of the box--I didn't reformat any of them.
[Nexus 7 General] JaSauders:
That's what confuses me. How could EXT3/4 not be as easily compatible with Android being heavily Linux based? *head explodes*

From earlier in this thread:

What the...
[Nexus 7 General] r0zj0k3r:
WiFi

What about a Wireless hard drive? maybe not the cheapest, but probably the easist implemetation (easier than OTG USB using ext2/3/4) of mass storage without resorting to what google wants you to use i.e. their cloud products. im just saying....:D
[Nexus 7 General] JaSauders:
That's what I'm beginning to lean towards. I find it exceptionally frustrating that I've been hearing completely conflicting results.

EXT3/4 are confirmed as working with USB OTG

Stick Mount is lackluster, use USB OTG Helper instead

FAT32 is the only supported file system that does RW

No really EXT3 works fine here

What I've seen so far... is FAT32 is the only file system that gives even the slightest hint of reliability. I've tested this on a 500GB WD HDD as well as two different flash drives - one 4GB Kingston and one 4GB by "Lifetime Memory Products". All same results. I just cannot put into words how confusing it is to me that FAT32 is more easily supported than EXT3/4 on an Android platform. I mean, really?
[Nexus 7 General] r0zj0k3r:
Tried a new app today, USB Mass storage watcher OTG. It requires root, and busybox, auto mounts and allows for manual mounting of OTG USB including ext4(haven't tried any others, time for work....) ! Looks like no rw capabilities though. For now, that is OKAY for me.
[Nexus 7 General] gruiz3:
Is there any pin layout changes or any usb host cable works?
[Nexus 7 General] JaSauders:
OTG USB cables are very different vs regular MicroUSB cables. OTG makes a difference.

By manual mounting, do you mean straight up terminal using Linux commands to mount, or by simply hitting a manual "mount" button?

But you say EXT4 works, just as read only? Hmmm...
[Nexus 7 General] further_sky:
Is there a way to prevent the nexus 7 from charging my storage device? I'm using my Archos 605 80GB as storage which means it already has power. If I can stop the charging then I can save some battery on my nexus 7.

Thanks
[Nexus 7 General] r0zj0k3r:
It's a mount button. I haven't had the chance to see everything the app does. But it does handle ext4, as any of these utilities SHOULD, and if I had to guess I would say it just utilizes bash scripts to mount with busymount. I couldn't get it to mount with rw.
[Nexus 7 General] JaSauders:
So, we're moving forward. It seems as if BusyBox wasn't installed, despite being installed... BusyBox was installed from the play store, yes, but I decided to open it and check it out, and I noticed there was an install/uninstall button. I hit install and decided to see what would happen. Ultimately it said successful, so I went over to USB OTG Helper and sure enough, it stopped erroring out about BusyBox. I guess I didn't understand what you folks meant in regard to "where did I install it to". I guess it wasn't entirely installed in the first place!

At any rate, NTFS seems to accept read/write now. I just moved a bunch of downloaded images on the tablet to the flash drive and they popped up fine on my Ubuntu laptop.

Despite this, I would still love to have EXT support, for no reason other than it's what I use on all of my devices anyway... Is there anything to change or another app I can get that'll support EXT2/3/4 with USB OTG on the N7?
[Nexus 7 General] spthacker:
Dunno what I'm doing wrong as I can see my mounted 16gb stick, but when I navigate to the folder it states its empty??

[Nexus 7 General] JaSauders:
So basically I'm looking at two options. One, I buy a 2 dollar app and have otg fat32 support... Or I root, save 2 bucks and also have fat32 support. If this app supported more file systems, I'd be game, but I'm not sure what the point is to buy an app that gives me the same file system support with otg, especially considering I'm already rooted. :(
[Nexus 7 General] Solange82200:
I bought this app straight away.

But I just can't work up the nerve to root this device. It seems so complicated, and it's so perfect as is... But now that this app is out I can have the option of extra storage, which is super cool :)

That is awesome. I don't know much about these things, but is there any difference between using a small one like you have, and one of the cable ones? I'm just curious if there is an upside to having the tail/cable looking ones, seeing as so many people get them over this small one (which personally I would prefer, the smaller the better)?
[Nexus 7 General] JaSauders:
Sounds like a pretty sure-fire win for ya. Really the only reason I even want the extra storage option is for a trip coming up where I'll be doing some hopping from one plane to another... otherwise I certainly don't need to have my video library on me at all times, etc. I'm okay with FAT32 if that's the only option. I just hate to convert everything to a lesser sized video JUST to fit it on external storage to utilize with the tablet. I mean, sure, I could do it, but if only one of these flippin apps would support EXT2/3/4, I wouldn't have to. :mad: Even if it's (somehow) impossible for EXT2/3/4 to be supported, I'd at least like to know why... :(
[Nexus 7 General] bubblesmoney:
i am pretty sure i read elsewhere on xda about ext2/3 being supported in some roms. i dont know anything about these issues but i did read something to that effect a week or so ago on an unrelated thread. just search on xda nexus 7 forums for those threads if interested.
[Nexus 7 General] Serial_Noob:
Impossible? Apparently not. According to this, the Nexus S uses ext4.

[Nexus 7 General] Milamber33:
So does the Nexus 7. That's why it's so confusing that Stickmount won't mount external storage formatted as EXT4.
[Nexus 7 General] JaSauders:
Quoted for the unbelievably accurate and insanely baffling truth.

It's the equivalent of Windows phone not supporting NTFS, but supporting EXT4 instead. :eek::eek::eek::eek:
[Nexus 7 General] live2die:
i use stickmount.apk and it works great for me
[Nexus 7 General] r0zj0k3r:
Stickmount works well with fat and ntfs, since this what most of the world uses. It makes sense to support both. Not supporting ext4 just seems lazy when your OS runs on a modern Linux kernel.

I'm not sure why "usb mass storage watcher OTG" isn't working on a rooted device with busybox for some people. I have used this app on 3 different kernels supporting 3 different ROMs. For those interested I am using Glazed JB 1.1.2, which is a modded cm10. I can run usb mass storage watcher OTG out of the box, and it supports all file systems. Ext mounts read only, but I only need it to be read only so all is good.

There are two apps

"usb mass storage watcher OTG"

And

"usb mass storage watcher"

Make sure you have the one that supports OTG.

[Nexus 7 General] JaSauders:
If you know a place where I can trade in my 500GB external hard drive for a 500GB wireless hard drive without spending a dime more, I'd love know. There's no reason I shouldn't be able to utilize the drive I already own.

When you say it works with stickmount, you're referring to read only, right? If I recall I think that's where I ended with it.
[Nexus 7 General] MaxNXS:
Just reporting on my USB OTG experience with my Nexus 7 (stock rooted rom). Just got this adapter from Amazon. Using StickMount I was able to mount and use regular USB flashdrives.

Updated with more info:

All the USB flash drives I tried had been formatted as FAT32, I was able to read and write to the drive, I was able to open documents (pdf, txt) as well as playing videos (avi, mkv) directly from the flash drive using Dice Player.
[Nexus 7 General] JaSauders:
Okay... but there's still a lot of questions that could come out of your experience. What file system did you use on your USB drives? Were you able to read AND write from it? Were you able to launch videos and other files directly off of the flash drive?
[Nexus 7 General] MaxNXS:
Sorry for the lack of details. All the USB flash drives I tried had been formatted as FAT32, I was able to read and write to the drive, I was able to open documents (pdf, txt) as well as playing videos (avi, mkv) directly from the flash drive using Dice Player.
[Nexus 7 General] JaSauders:
Thanks for the update. Yeah FAT32 sounds like the only real read/write solution right now. I REALLY want to be able to utilize a different file system without a 4GB limit with full read/write capabilities, though... :(

I rooted my Nexus 7 with Nexus Root Toolkit v1.5.2 and installed:

USB OTG Helper v 4.0.0

http://xdaforums.com/showthread.php?t=1588940

I can mount, read, and write both microsd cards formatted FAT32 and a 96 gig SSD formatted NTFS.

(Kingston SSDNow V+100 SVP100S2B/96GR 2.5" 96GB)

So far, no problems with 5+ gig files. Media seem to play fine with dice or mx.
[Nexus 7 General] JaSauders:
Thanks for your input. I'll be checking this out tonight! (that link looks incredibly familiar though - I think that's the USB OTG Helper I already have where I could only read NTFS, but I'll double check)

Also, thanks for the SSD idea. I have a 60GB SSD and an enclosure that I'm not using that would serve this purpose beautifully.

EDIT - Cancel that. I remembered just now I have my OTG cable on me. I took a 4GB flash drive, NTFS'd it, plugged it in to the N7 and wrote some files to it fine. I plugged it in to my Ubuntu laptop and I could see the new files. Super glad NTFS works so I don't have to deal with the 4GB limit.

I do have some questions, though. What exactly is BusyBox? I remember BusyBox being something I needed in order for USB OTG Helper to work. I read a few reviews of it on the play store and some people there even said, you really have no idea what this thing does other than the fact it's required for some different apps to function. Likewise, some other apps that require it now have it "baked in" so they don't need to install it separately. Can anybody fill in this gap?

Lastly, one I've already asked many times but I simply cannot wrap my brain around it is how on earth an EXT file system isn't supported. Don't get me wrong, I understand that most Android users are likely Windows users, etc etc., I get that. It's just the fact that Android is very Linux oriented and there seems to be no EXT functionality there. If it's possible and there's just no apps with it supported, fine, but more and more I'm beginning to wonder if it's actually flat out impossible. *head explodes*

Also, how is USB OTG Helper different from Stickmount? They seem similar in practice, but obviously Stickmount seems to have some degree of limitations considering it's only FAT32 read/write, NTFS read only, and no support for EXT file systems (despite earlier reports *somehow* saying yes, read/write supported fine on FAT32/NTFS/EXT2/3/4).
[Nexus 7 General] spthacker:
Wonder if anybody an advise please, tried both stickmount and usb mass storage watcher OTG......
