[Nexus 7 (2013) Q&A] Tryptonite:
Has anybody successfully mounted a 64gb usb 3.0 drive? I have no problems with a SanDisk 32gb usb 3.0 drive but when I try a Silicon Power 64gb usb 3.0 drive it can't be found. I've tried Stickmount and USB OTG Helper and the LED indicator blinks and both programs start up automatically when I plug in the drive but it's not found. My USB OTG cable works for the Sandisk 32gb but not the Silicon Power 64gb.
[Nexus 7 (2013) Q&A] ncotton:
I've got the same issue with a lexar 64gb usb 3 drive. Smaller drives mount fine but this one appears blank when mounted via stickmount on my nexus 7 2013 edition.
[Nexus 7 (2013) Q&A] smelenchuk:
How's the drive formatted? I imagine here's a good chance a 64GB flash drive will be formatted with exFAT, which stock Android can't deal with.

(That said, I have a 64GB drive here which came formatted with FAT32... and no tablet to plug it into yet...)
[Nexus 7 (2013) Q&A] Tryptonite:
The 32gb that works and the 64gb that does not work are both formatted with NTFS. I can't use FAT32 because of the file size restrictions.
[Nexus 7 (2013) Q&A] smelenchuk:
Hmm... I'll dig more into this when my own device actually gets here.
[Nexus 7 (2013) Q&A] ncotton:
I've tried NTFS and exFAT with any luck, and I've confirmed stickmount is working with those file systems on smaller usb 2 drives.
[Nexus 7 (2013) Q&A] smelenchuk:
Are the drives mountable in recovery? I often have better luck there than in main Android.

If they're not, it might be some strange hardware-related issue.

UPDATE: Device is in hand; drive mounts properly and works properly here, so can't really troubleshoot further from my end.
[Nexus 7 (2013) Q&A] Tryptonite:
Have you tried to mount it as NTFS?
[Nexus 7 (2013) Q&A] smelenchuk:
No, but exFAT appears to work fine with the right software in place, at least. I'll give NTFS a spin at some point and let you know what transpires.
[Nexus 7 (2013) Q&A] stultus2:
I am also having problems with 32GB freshly formatted (Win7) NTFS drive. No files are recognized. 16 GB FAT32 works fine. Using stickmount on freshly rooted install.

[Nexus 7 (2013) Q&A] stultus2:
Fixed my NTFS problem. I didn't have the NTFS binaries in my root drive for stick mount to use. Of course, that was nexus media importer and $4 later. But I'm happy I figured it out and will be sticking with stick mount. When in doubt RTFM!
[Nexus 7 (2013) Q&A] lil25jai:
I have a 32gb Kingston 2.0 USB drive, which it mounts, but once I open with VLC or a file manager app, it unmounts it. Stickmount kind of flashes a bit, and then shows "active mounts" as None. Did anyone have this issue?

On another USB, I have a 64GB Lexar 3.0 Drive. This one mounts fine, but once I got into the drive it was empty. I'm having the same problem with some people here who has a 64GB drive. The format on this was Fat32, I've used the hp usb format program.

I also have 2 Adata USB drives, one is 16GB and the other 32GB. These 2 works fine, no problems.

Hope someone knows why my first USB (Kingston) unmounts itself once I tried to read it...
[Nexus 7 (2013) Q&A] solnyshok:
Did you check how your drives are formatted? using FAT32 with cluster size of 32768 usually works well
[Nexus 7 (2013) Q&A] kitch9:
Guys, I've got a working OTG fix that does not require root after much messing about!

Go to settings and disable security lock screen then select English US as the language.

Insert OTG cable and start Nexus Media Importer.

Reboot.

Nexus Media Importer should now pop up as usual and OTG should now be working.

Change language back but do not reboot as you will have to repeat these steps.

Seeing mixed reports here. Is usb HD support only via stick mount?
[Nexus 7 (2013) Q&A] lincolnskilz:
I've just purchased the nexus importer and it works with my OTG cable. It's odd cause when I plug in the OTG cable to my s4, it reads it. But on the nexus, I have to purchase the nexus importer for $4...
[Nexus 7 (2013) Q&A] bozint:
So the general consensus is that OTG with Root+StickMount works, right? There are some isolated cases of variously formatted drives, but it does work. I wouldn't mind paying for NMI, but I'd root anyway and StickMount is free which equals more money to spend on some cool games.
[Nexus 7 (2013) Q&A] adit9989:
Stick mount works, no problems. Drop the fuse binary files also for exFAT support and you can use standard exFAT formatted 64GB cards. Did not try NTFS.

Stickmount will give access from ANY application (it's more like a driver). NMI will give you access only inside the app itself, from what I know, so not the same thing.
[Nexus 7 (2013) Q&A] bozint:
I was using StckMount on my GNex before and it worked flawlessly. The N4 obviously doesn't work.

Not really interested in NMI, just mentioned it as an option. I also don't use exFAT, my sticks are all NTFS, so I guess I'm good to go with root+stickmount.

Thanks for the reply though. Cheers!

issue with OTG

hello, i have a stock rom 4.3 JJS15Q, rooted with wug's nexus root toolkit (without custom recovery... or i could not root...)

i can't connect any usb storage.

i tried stickmount: no drives to mount

i tried OTG disk helper no result..

when i stick a USB flash drive it looks alimented (flashing)

My OTG cable works fine with my galaxy S2

anybody could give a hint??

thanks a lot!!, my tablet was set in french!! you made my day!!! stickmount now work fine!!

but so far only flash drives in FAT 32 mount...

no HDD mount, (FAT or NTFS) alimented or not...

OTG info

I looked and read about them. Well instead of buying one off of Amozon or EBay, I made my own. Its not that hard to do, I just followed a tutorial that I found using google to search on how to make them.

[Nexus 7 (2013) Q&A] Old-school:
For what its worth, usb-otg works perfectly fine on stock cm 10.2. I use it with my fiio e7k USB DAC, and there is now a mode for that in DSP manager too. Makes up for the only shortcoming of the new n7, the high SNR on the headphone jack.

I think what you really need is a a custom kernel with usb-otg enabled. I have moved to Franco now and everything still works perfectly fine. I could not get it to work on stock rooted even after installing a bunch of apps.

Just a warning to others, try all options before you get new cables/usb drives. I've seen plenty of threads

where people have tried stickmount, it didn't work, and they were told it was there cable or reformat drive.

Obviously, either I did something wrong with stickmount, or it doesn't work properly with the New N7.

:)

Hi,

I'm having trouble with stickmount as well. Hopefully someone can help here.

Had a N7 (2012) and that worked fine with my cable and both 32gb and 64gb drives.

Swapped my N7 for a 2013 version (when the 2012 got a fault).

Now my new N7 will only read the 32gb drives.. It mounts the 64gb ones, but nothing seen. (formatted ntfs)

Got a rooted stock N7 (build JSS15Q).

Any ideas..

:(

[Nexus 7 (2013) Q&A] chocobo2k:
By getting OTG to work you mean getting it to work while still charging the Nexus 7 with juice? Or it can only work in host mode without charging?

[Nexus 7 (2013) Q&A] DC_MTP:
reformat to exfat and if rooted make sure your using a supported kernel.
[Nexus 7 (2013) Q&A] PJ Clifford:
If you haven't already, read the full description for Stickmount in the Play Store. NTFS and exFat are not natively supported. It needs a "helper" library for each format placed in the root of the sdcard. Links are provided for the libraries in the description.
[Nexus 7 (2013) Q&A] Ceiryus:
stickmount

Hi, I've recently re-installed chainfire's stickmount on my new nexus 7 2013. While it works great, I am finding a small issue when I unmount my USB it also unmounts my internal SD as well. So when I go download a file i get a message saying "SD not found". This is fixed by rebooting.

Searching around i found http://xdaforums.com/showthread.php?t=1400034 which is chinfire's stick mount, near the bottom:

"SD card unmounting: If your SD card unmounts when unmounting a USB device, you have a bug in your kernel. This is not a bug in StickMount !"

I am also using Franco Kernel r3 on my nexus 7 2013. Does this mean Franco Kernel has a bug or is it something with stickmount?

[Nexus 7 (2013) Q&A] thedan55:
Using sick mount and USB otg helper worked perfectly for me. I'm on faux123 kernel. I tested both apps.

The only problem I have is that I can't seem to write to an ntfs drive but I can read from it no problem.
[Nexus 7 (2013) Q&A] midnite_blue:
writing to a NTFS-formatted drive or partition

Congrats, thedan55, on your solution!

Regarding NTFS write, I don't know of any app that can handle that right now. This is what Chainfire has to say about this issue (in the Play Store description of his StickMount app):

StickMount can utilize the "ntfs-3g" and "mount.exfat-fuse" binaries to add support for ntfs (untested) and exfat, but these are not included. If you place the "ntfs-3g" or "mount.exfat-fuse" files in the root of your internal storage ( /sdcard ), StickMount will automatically use them.

You can find the needed files here:

ntfs-3g: http://xdaforums.com/attachment.php?attachmentid=1145436&stc=1&d=134029380

[Nexus 7 (2013) Q&A] shantusingh:
Guys I am new with nexus 7 2013, please tell me as I want to buy it. So if I buy nexus 7 16gb base model ...

1) Can it not detect otg (attached with a pen drive) on stock ?

2) If no then for that I do have to have Nexus Media Importer and follow steps by kitch9 ?

3) And if I get nexus media importer, can it also run 3g usb data card internet as well using otg ?

Would highly appreciate the help!
[Nexus 7 (2013) Q&A] goofball2k:
1) No, it cannot

2) Yes, if you do not wish to root. If you root, then you can use stickmount. If you wish to unlock the bootloader and then run custom ROM, you don't need either app assuming the ROM you choose supports mounting USB OTG natively. I have used several which have this built-in.

3) Not to my knowledge. I have only tried with a rogers module and it cannot since it requires software to install to connect to Rogers network.
[Nexus 7 (2013) Q&A] Yuccaman:
Will only answer Q1....

Stock can recognise a USB Stick as mine does just fine. However, I did need an app to do this and chose USB Stick Plugin-TC, which is an add-on to Total Commander which is my File Manager of choice.

Plugin was 50p (UK) and allows read / write of FAT drives plus reading of NTFS drives as well.

There may be alternatives, both paid and free....
[Nexus 7 (2013) Q&A] midnite_blue:
1) The term 'stock' -- or 'as is from the factory' -- gets used differently by different people out here. There's

stock hardware

,

stock firmware

and

stock software

.

a)

stock HW

: technically, stock is not enough, since the OTG cable you need isn't “included in the box“... but it's NBD to get one.

b)

stock FW

: (this is how I've come to use the term) stock Android will be fine... you don't need to root.

c)

stock SW

: Nexus tablets don't come preloaded with the software you need, but the old stand-by, the standalone Nexus Media Importer, which has its own file manager, handles this well, as does the newer USB Stick Plugin-TC, which requires Total Commander, as Yuccaman said. I use both... and (just to avoid confusion) both support FAT32 as well as FAT (which is how we used to refer to FAT16).

2) Unrooted, you'll need either NMI or USB Stick Plugin-TC to import streaming NTFS-formatted media files or to read/write files using FAT16/FAT32 file allocation tables.

Stock N7 OTG Supports Canon S100 Compact Camera

Hi all, just joined this forum however been reading up much on the development, pretty amazing and a big thanks to those developers.

First hand experience when received 2013 N7, no additional App was installed but when OTG cable couple with USB cable was able to read and import photos directly from Canon S100 Compact Camera.

At stock N7 could not read any USB drive (flash or HD) but was able to connect a USB mouse

After rooting and installed 2 Apps, Stickmount and USB OTG Helper, was able to read and write from flash drive and SD cards. Canon S100 camera was still able to mount, USB and Bluetooth mouse OK. Using 4 port USB without 5V supply OK

Things that did not work out

- Nikon P310 compact camera was not able to mount (probably the supply camera had different connection, not micro USB)

- Tried all Portable Hard Drives but failed mounting (using OTG connect to USB Y cable with 5V input)

So I am not sure where has it gone wrong.

Current system

4.3 Android

Kernel 3.4.0-g9e52a21

Build number JSS15R

There are only 2 more setup I am interested in

- connecting to AverMedia DVB-T

- mounting portable Hard Drive able to read and write

If anyone can advise, much appreciated.

PS Do not wish do to another wipe out again.

Cheers

[Nexus 7 (2013) Q&A] midnite_blue:
look at the amps...

Welcome, scx2000, and congrats on that auto connect of your Canon's card. Yes, the N7 comes with a USB mouse driver out of the factory.

When you wrote '4 port USB without 5V supply' were you referring to an unpowered USB hub? Are the HDDs you tried 2.5 or 3.5?

I'm pretty certain the N7 won't be able to provide a portable 3.5 HDD with the amps it needs. Even if it did, I wouldn't want to treat my tablet battery that way.

Did you try a powered hub? Make sure the amperage is adequate to spin your drive.

(Seagate tech support has recommended a wireless HDD generating its own hotspot. Though this thread is about using the USB port, I thought I'd mention this possibility to you.)

[Nexus 7 (2013) Q&A] Squire-au:
I'm having probs with stickmount on a rooted N7-2 as well. I've got two OTG cables, one with the extra plug for power for my HDD, and one without. Stickmount works erratically on USB sticks - of various types and sizes - and HDD mounting is not usually successful. I've got my language set to English US, even though I'm an Aussie... I just have to put up with the spelling mistakes.

Anyways, I have 2 WD external HDD's. The old USD 2.0 320GB one has worked reliably on everything I've plugged it into for the last 3 years, and it still does. But 3 new Seagate USB 3.0 drives wouldn't mount at all - no matter if I formatted FAT32, NTFS or exFAT. No matter what cable I used. I just bought a 500GB WD My Passport Edge (For Mac) and it works perfectly as well. Strange, because I service NCR ATM's and they chew through hard drives, and both Seagate and WD seem to be as reliable as each other.

Anyways, I digress... I use Nexus media importer and find it reliable most of the time. I don't have much need to copy from the Nexus to anything else... I just want to carry my large video library with me when I go camping. I hate cables, hate plugging anything into my baby. Still waiting for my WiFi HDD thing to arrive, it should sort everything out. If it works.
[Nexus 7 (2013) Q&A] scx2000:
Thanks for the reply.

- 3 Portable HDDs are 2.5, 2 of which are SATA drives

- have tried external power source both USB and direct 5V input to the Portable HD

- drive is spinning but not mounting

- Did check on some Wireless HDD, found that they are slow in transferring big files and expensive too.

- If was to use Wireless, rather get something like D-Link DIR 505 router, repeater, charger and able to connect portable drive. Function much better than those Wireless HDD.

- At the moment rather find solution at current disposal but something like D-Link is worth looking at.

My 500GB WD My Passport drives worked fine with my 2012 N7 without external power but won't work with my 2013 N7. My 1TB My Passport would not work without external power on my 2012 version so my guess is that the 500GB drives may have been on the hairy edge of working/not working and now the 2013 N7 puts out just a little less juice so they fell on the other side of that hairy edge. Using a USB 3.0 Y-cable, I can connect to an external battery pack (or powered hub) and the 1TB drive works great with both the 2012 & 2013 versions. I'm stock and use Nexus Media Importer.
[Nexus 7 (2013) Q&A] midnite_blue:
Cheers! Your D-Link router/hotspot idea sounds great, especially for larger uploads like full backups. (BTW, I wonder if hotspot-generating sd cards -- Eye-Fi, Toshiba, Transcend -- are as slow at data transfers as wireless HDDs.)

Anyway, I think I get it now that the HDD “direct 5V input'' you referred to is AC power sourced at the wall. I was wondering, when you attempted to mount the drives, did you get any kind of message on your N7, like something about file formatting?
[Nexus 7 (2013) Q&A] scx2000:
That's one of the best option I can think off using a portable travel router, at the same time could extend the WiFi range. There are few models out there, so I'm looking for a specific type with options of routing, repeater, WiFi b/g/n, 3G, internal battery with phone charging option and support USB. TP-Link MR3040 is one such model. The 3G option is great for traveling, just need to get the 3G card from that country

As for the N7, there was no error msg. It just did not mount.

Anyway just ordered Samsung OTG Y cable to test it out also the portable travel router

Conversation with Googler

Before I discovered this thread I sent the following to a Googler friend of mine:

His reply:

Later, he added (following further research):

He also said:

There's relevant discussion here: http://productforums.google.com/forum/#!topic/nexus/LY58i10EG6k

Key points to note:

1) There's another app to try if all you want is to view photos - https://play.google.com/store/apps/details?id=com.homeysoft.nexususb.viewer

2) Android 4.4 release (KLP/KitKat) will add native API support for reading external storage devices, so it seems likely that Nexus devices which support USB-OTG will gain the ability to read external storage natively (i.e. in the same way that we currently require root / custom ROMs for) once KLP/KitKat is released for them.
[Nexus 7 (2013) Q&A] midnite_blue:
Thanks for sharing this dialogue, marcusjt. It's potentially really great news!!

I assume your friend, by saying 'primary external device,' is referring to the emulated SD card in the Nexus line.

It would be an important step to have native support for transient USB-connected external memory storage, even if it were limited to streaming access to external data, which your discussion with your friend focused on. (Nexus Photo Viewer, BTW, is Homesoft's read-only version of its Nexus Media Importer, the app regaled in this and other threads as a pioneer in not only reading but -- despite its name -- writing to external storage.)

And thanks for the interesting detail about the USB mounting bug, discussed at length on xda, to be found on the Google product-forum thread you linked us to:

There's a bug in Android 4.3 related to mounting USB OTG devices due to an invalid assumption about mounting time and all manner of other things. A fix was committed to the AOSP repo a few weeks back so I would expect it to be sorted in the next Android update. 6 Oct​

I could be reading your friend's comments wrongly, but it sounds like those of us out here who do not have SD card slots may have to wait until after Android 4.4 to reap the benefits of some of these new initiatives.

Let's hope the API's under development do indeed attend to both the reading of and the writing to external storage... data transfer should be a two-way street!
[Nexus 7 (2013) Q&A] marcusjt:
You're welcome, yes it is!

I assume so, given th reference to "secondary external storage that is a semi-permanent part of a device, like the physical SD card in the Galaxy S4"

If by "after" you mean when Android 4.4 is released, then yes, it sounds like it...

One would assume so...

In all cases only time will tell... :D

Harddrives without external power are always difficult on USB OTG. Only some of them really work without additional power. Better use a bigger USB stick.
