>Anyone know if using (or maybe already tried) the usb cable that comes with the Nexus 7 coupled with a female A to female A usb adapter will allow the OTG connection to work with a flash memory stick please?

USB OTG requires a 5th ID pin (grounded = host, open = peripheral). A standard (non-OTG) USB cable has only 4 pins. That said, host/client switching can be set in firmware, and you don't need to have a OTG cable if using a custom ROM that allows for such. Said custom ROM--which is probably imminent--can also deal with automounts, removing another hoop (StickMount) you need to jump through.

>My 8gb is on the way and I doubt I will even use all of that with everything connected to the cloud

I'm curious how much of the 5.5GB space will remain if you opt to download (as opposed to stream) the freebie Transformer flick. I don't imagine there'll be much space left.
[Nexus 7 General] stuntdouble:
Good to hear. Thanks for the info. :good:
[Nexus 7 General] JaSauders:
Is there any news on a ROM that supports automounting and whatnot as of yet? I see no harm in relying on StickMount, as according to users it seems to work great. I'll likely be staying with the stock ROM/StickMount/rooted unless I find some incredibly compelling reason to flash it to another ROM...
[Nexus 7 General] superflysocal:
Yes, I just figured how to do it with ES File Explorer. Just tether to the phone first. You can even tether to it with bluetooth to save battery power, although it is more unrelible of a connection for streaming. Works perfectly with wifi.

Hi,

Here's a video of me testing OTG with Root and StickMount.

I plugged in a 2.5"HDD it work fine (Can't write with Solid Explorer to NTFS tho) ***Edit*** Found a solution for NTFS Writing, use this http://xdaforums.com/showthread.php?t=1588940 - works like a charm.***Edit***

Also I plugged in my Canon 5DMKII and it work flawlessly. (Except as in ICS doesn't RAW and Video Files)

If you want to import RAW Files you can use a cheap Card Reader (Also tested of camera and it worked fine)

Here's the video.

Sorry for the quality, One X, One Hand, Low Light, ****ty Autofocus hehe.

[Nexus 7 General] JaSauders:
Is it true that one 2.5" external HDD vs another 2.5" external HDD could differ in power requirements? Reason I ask is I have two external HDD's, a 160 and a 250. The 250 is super picky about where I plug it in (WD). If I plug it in the front of my tower, it makes a small chirp sound, which reminds me of a baby squirrel hiccup or something. If I plug it in the back, it spins up fine. The 160? Fine all around. Both are 2.5".

Perhaps the size difference (maybe the 250 has more platters to spin?) requires more power, etc.
[Nexus 7 General] Nexcellent:
I just realized that the 2.5" i'm using is a 7200 RPM drive, it's very likely that it's simply not getting enough power from the N7. The chirp is the heads moving out of the parking area. It's the capacity of each platter vs. the number of platters as far as size goes, at least on drives from the past decade. I have to check if 5400 RPM drives work. Good thing i work in the hard drive industry, i can test a bunch of different drives :)
[Nexus 7 General] e.mote:
>Good thing i work in the hard drive industry, i can test a bunch of different drives

CasseTrop looks to have a 2.5" working, although I can't see if he's using ext power source. It would be nice to determine the max current (@5V) the N7 can put out. That, plus the spin-up spec for the HDD should tell which device is usable sans add'l power. Have a clamp-on ammeter?

[Nexus 7 General] hotleadsingerguy:
lol what? You're making this a question of morals? Apple sells a tablet that costs $316 to make for $500. Their 64GB 4G model costs 49% of the overall cost to make...meaning they make back more than twice what they spend to create it. So far it's suspected that Google spends $187 making the Nexus 7 and sells it for $200. The estimated cost of the 16GB model is about $10 more (there are no additional slots, so the memory must be "replaced" with the higher capacity memory) and sells for $50 more.

My point? Apple adds an additional slot of memory to an iPad and sells it for $100 more (cost of around $10), while Google replaces the memory already installed and sells it for $50 more. Don't make it a "question of morals". Boycott all you want, but don't make up lame excuses to do it.

Personally, 8GB is fine. I'm not sure how people use so much space for apps...my Galaxy Nexus and RAZR Maxx both have over 50 apps and are using somewhere around 2GB a piece. That includes games like Shadowgun and GTA3. If you're filling up 8GB with apps you should really think about spending more time with the rest of humanity, because the only way you'd use anywhere near that amount of space is if your eyes never come off the screen.
[Nexus 7 General] adiliyo:
Nova3 (if it ever becomes compatible) is almost 2gb by itself. I don't have that much stuff on my 8gb n7 but I'm down to less than 2gb free.

I think $50 is a fair price, they need to have enough of a price change to keep the 8gb relevant sales wise, I feel like anything less than 50 and no one would buy the 8gb model.
[Nexus 7 General] clockcycle:
I check there and ebay as well but they never have the ones I like which are smaller. If they do they are usually crazy hiked up $$, so I prefer to wait. There are some "US" vendors in Ca that cheat actually come from China.

OTG not working on my Nexus 7

I installed stick mount from play play store, and I can't get my flash drive to be seen or mounted by the tablet. Yes, I'm rooted, and all that. I have the OTG adapter from Amazon Prime, a 32GB microsd card in a micro-sd adapter plugged into the OTG adapter. Nothing at all showing up or mounting through stick mount, or anywhere else for that matter. I am running Poitee's Nexus 7 CIFS,NTFS,USB-OTG kernel.

I don't know if it might be a bad adapter, or if I need a stand-alone usb flash drive stick, as opposed to what I have described above.
[Nexus 7 General] Censura_Umbra:
Probably cable. But make sure you didn't accidentally block permissions. Also try unplugging, rebooting then replugging.

Also try plugging the USB into a computer to make sure it works. While you are there, make sure it is formatted as fat32
[Nexus 7 General] Censura_Umbra:
No problem with the nexus 7
[Nexus 7 General] thestrangebrew:
I've got a question about using the USB OTG & power. I just got my flash drive & OTG cable and I'm at work so I haven't been able to try anything out yet. But I'm wondering, if the OTG cable is plugged in, is there a verified way to get power to the N7 as well. I haven't been able to read all 47 pages of this thread, but I did see a few suggestions, mostly about getting a USB hub. But I'm curious exactly how this setup would be connected (never used a hub before). I'm assuming it goes along these lines:

USB stick/sd card/whatever -->USB Hub-->USB OTG-->Nexus 7

\/

USB 2.0 cable to pc/power supply/wall socket?

Is that the topology and has this been verified to work as far as charging/powering the N7?
[Nexus 7 General] Mischaseb:
For those having issues getting their storage to be recognised, it won't work if formatted as ex fat. Your storage should be formatted as fat32 and then it will work hopefully :)
[Nexus 7 General] Censura_Umbra:
You would need a cable that acts as both a charger and splits off into a USB input.

However, once we have a docking station that uses the pins on the side instead of the micro USB port, then we can charge and access storage.
[Nexus 7 General] IPvFletch:
I got a "Samsung OTG" cable on the way, and a 16GB Kingston flash drive - someone else confirmed these two part numbers as working (with Stickmount+Root+FAT32 formatting).

BUT, am I now reading you need to flash your Kernel to some custom "OTG-enabled" Kernel??????
[Nexus 7 General] Mischaseb:
incorrect. Rooted stock + stickmount = working usb storage :)
[Nexus 7 General] CrittendenWildcat:
Rooted this afternoon. Rooted + Stickmount with OTG cable on stock is all you need.

I just tried to attach my 1 TB portable external hard drive to the Nexus 7, and it gave me heart palpitations because the hard drive made a sound similar to the click of death. But hooked it to my desktop and she's reading fine. Guess it's not pulling enough juice from the Nexus 7 to run properly.

I tried a 8 GB (USB 2.0, FAT32) and a 32 GB (USB 3.0, NTFS) USB stick, both worked fine.
[Nexus 7 General] IPvFletch:
Yeah I heard legacy hard disk drives need more power - you might get lucky if you have a SATA/IDE > USB enclosure which has a separate power plug though..

Ok, I don't know why some people are proudly sporting their "OTG kernel" but whatever, clearly they did it without doing adequate research first. But whateva.. I rock custom kernels too, but I do it for a reason (used to be for things like cpu control for the EVO, or tun support/driver for various devices, etc...) Glad you don't need to do that for the 7 but it still sucks you have to root it. I don't mind rooting mine but my neighbor will likely mind (me) rooting his.. But hey he could have got the 16GB and then he could have STFU but noooo, he had to follow my lead and skimp with the 8gigger.. sae la vie.. :cool:
[Nexus 7 General] Jordanooo:
Has anybody tried storing a nadroid on the external drive and accessing it directly from CWM?

If so, does that work?

EDIT: What i mean is, you boot into cwm and restore a backup from the external drive
[Nexus 7 General] thestrangebrew:
I'm not sure about an OTG kernal, but mine worked fine also with just root+stickmount. I didn't even have to use root explorer or anything else to find my files.
[Nexus 7 General] spiff72:
I am curious about this too. This could be a killer feature for crack-flashers like me. Nandroid backups are a big space hog - but the newer CWM6 with incremental backup helps for this somewhat. I might try it later on. I suspect that for there to be a chance of it working, the drive will need to be formatted in EXT3/4 (not FAT32).

The other question I have is whether you still need to transfer files (like video or audio) to the tablet - then the USB drive before you can play them directly off the USB drive? This was a limitation mentioned way back (a week ago?) when I initially read through this thread. Has the update to the StickMount app fixed this? And can it also play from a FAT32 formatted USB drive now? (It had to be EXT3/4 before).

Thanks
[Nexus 7 General] japzone:
I have OTG working on my N7 with Root and Stick Mount. MXPlayer works fine playing videos directly from the connected USB Drive. Tested with a 16gb Flash drive and a 2tb external drive with its own power supply. Every file browser tested worked completely fine.
[Nexus 7 General] japzone:
As of right now Backing up/Restoring directly from OTG is currently impossible because of the requirement of the Stick Mount app.
[Nexus 7 General] savalangh:
WOW

Its great,

I connected N7 to a galaxy s (rooted, USB debug off,dual mount SB on) and simply browsed my galaxy's SD card.

I could confirm that video and music streaming, opening document files and copy and paste any type of files and folders are easily possible.

The sad thing is since those are connected, Galaxy s starts charging from tablet and courses battery drain for N7
[Nexus 7 General] Pond-life:
I think that makes it worse if you flash a lot of different roms as it's harder to just remove old backups to clear space.
[Nexus 7 General] spiff72:
The killer feature I was referring to was the ability to offload backups on an external memory device - thus freeing up at least 2 gigs of space. The problem is I would end up being somewhere without that device in my possession (or without the OTG cable) and I would be unable to restore a backup.

It sounds like it is a moot point anyway - the backup can't be done externally because of the need for Stickmount.
[Nexus 7 General] japzone:
A workaround would be to make the Nandroid backup and then Boot back into the OS and then Copy the backup to a USB Drive using OTG. Not the ideal method but better than nothing. Get a cheap 32gb flash drive and use that to store your backups. Keeping the drive and the OTG cable in a pocket somewhere isn't hard so you could easily take it with you on your travels.
[Nexus 7 General] japzone:
I plugged my old tablet into my Nexus 7 directly and transferred my Titanium Backup files that way. It made migrating to my new device the most painless experience I've ever had.
[Nexus 7 General] spiff72:
I thought about that but wasn't sure if there would be any file permission issues with doing it this way.

Would it make sense to format a flash drive with EXT3 or EXT4 (which one is preferred?) and copy the files that way? I assume that this would preserve the permissions (while doing this with a FAT32 formatted drive may not preserve permissions?

Another thought - if you aren't able to boot to the OS to copy the files back (maybe a bad flash or something), this method doesn't give true "emergency" restore capability since you will need a PC to copy the files back.
[Nexus 7 General] david279:
It would be nice if I could run adb or fastboot cmds from my tablet to my phone while connected by a otg cable.
[Nexus 7 General] Twitchel:
Hey,

Hey guys,

Just thought I'd contribute to this thread with my experience. Yesterday I rooted my Nexus 7 and attempted to attach a 500GB 2.5" external hard drive. The Nexus 7 had enough juice to power the hard drive and I could directly play the media from the external drive using V player. V player atuomatically recognised the external storage and the fact that there was media on it too.

Hard Drive: Samsung S2 500GB 2.5" from ebuyer

USB Host Cable: Generic Samsung Galaxy USB host cable from play.com

Apologies for not providing links, my post count isn't high enough.
[Nexus 7 General] Jordanooo:
You could always keep a stock nandroid on the device memory (one with nothing installed). This would take up little memory.

Then, if you do have a bad flash, restore to that one to get booting, then transfer your latest nandroid to internal and restore that.

Maybe a bit of a hassle, but ensures you have a good, low memory nandroid ready for when needed

I've been using BSPlayer and as far as video goes everything seems fine.

Some things I don't like about it:

Play/Pause button isn't very responsive and their double tap to Play/Pause seems more like Tap once, pause, then Double Tap.

Can't swipe down from top to get notification bar without exiting video.

Needs option to lock screen rotation to landscape only since portrait mode for videos isn't really useful.

[Nexus 7 General] japzone:
I use MXPlayer as my primary player. It doesn't have any gestures for pausing but all of its other features are top notch and I can't find any other real annoyances with it. By default it scans the sdcard directory for media which picks up USB drives fine but takes forever to scan when you plug in a drive with tons of stuff on it. I personally set up my scan so it scans my Video and Downloads folder on my Nexus 7 and then I'll specify the usbdrive folder. When I'm going to plug in a big drive I disable the usbdrive folder scan and then specify the specific folder on the drive I want.

I will try to describe this. Every OTB USB cable i have found and purchase so far, is a right angled one, i.e when plugged in the cable goes up towards the side of the Power and volume buttons. Has anyoen found one the goes left(down towards the pins), the reson being when i lug the N7 into the keyboard case i have for it, the cable has to go up.. 1. puts strain on the port goign up 2. makes fitting it in the case harder.

I can turn the device around, but then the Power, and volume are on the bottem an dbecome proetty much useless. I have ordered about 10 diferent ones. some base off pictures that apear to have the micro slot turned the correct way. but alias, 10 cables all go upwards. Dang Google/Asus for not folowwing what the NeXus phone had..

You just need to use a Web Browser that allows you to choose the download folder, like Opera or Dolphin.

[Nexus 7 General] Milamber33:
I have a question. This is really purely academic, but would it be possible to have Stickmount working on an UNROOTED device if it were pushed into /system/app rather than just /data/app? Of course you'd need either root or a custom recovery to get it there, just curious if bundling it into a ROM or flashing it via CWM would negate the need for the device to be rooted.
[Nexus 7 General] r0zj0k3r:
I do agree with you, however all phones Web browsers and computers are set up for data mining. Google is probably the worst, but they do tell you what they do with the information and you can opt out of most of it. If you don't want data mining don't use the Web, or your smart phone ever. Or at least proxy and encrypt at every turn. If the nexus 7 had an sd slot we would just be *****ing about something else. :P

My experience with flash drives on hand has been mixed. My oldest, a whopping 128 MB FAT32, mounts & unmounts, but I can't enter the sda1 directory; works fine on in Unbuntu 12.04 desktop. Two others, one a generic 1 GB FAT32 from ~4 years ago, works fine; the other is an HP 8 GB FAT32, about 2-3 years old, works fine. The first one I tried, a 4-5 year old Lexar 1 GB works fine other than never unmounting. I initially tried it in FAT32, then EXT4, then back to FAT32 - never unmounts.

I have no idea why there are the differences in drives.
