Is there any way to ONLY mount the external SD card when mounting as mass storage?That would solve all of my problems..

Well, I think no known solution till date. A composite usb device, not plain mass stroage device!

Well maybe this can help to solve this, once i conected it to my car stereo, i was triying to conect it when i got an error end process of the usb conector it got stick on the display bar and when i reconected it worked, i never could make it again..... But ís posible i did it....

[Q] a little housekeeping a500 q's

Hello all
Just bought one of these off the net for the missus so ill be active around these threads as well. Personally i have a xoom this will be like my second to flash the heck out of lol but as I've been reading about these i have a couple small questions
1. Is the sd card working on stock rom so i can flash customs or will an update to 3.1 be required like the xoom?
2. Does the usb port work as host out of the box?
3. Whats the general stable oc you guys are achieving?
I have tried to search these but some are hazy on the specs or they are outdated
Cheers

Fastest claimed speed is 1.64ghz, stable closer to 1.5.
SD card does work on stock, actually is required for flashing. As yet you can't flash from on board only external.
USB seems to work for some devices not others depending on whether you use the full size USB or the mini. Look on the market for USB mount all, you do need fat32 not ntfs though
Anyone want to contradict any of this?

Cheers mate thats good to hear except for the host feature thats the whole point hoppwfulky i get a good one

Yes USB host [the fullsize USB not the mini] works out of the box. If your USB device requires power though - like some external HDD's - it may not work as there might not be enough power draw.
The mini USB is for the connection to your computer and SDK/ADB/general File transfer use - along side the Acer USB driver install [so make sure you've got the Acer USB driver installed on the computer(s) you plan on using to push files to the tab though mini-USB].

Yeh as i said im well advised due my xoom on rooting and android adb, drivers (not being a know it all smart azz) just those couple q got me thinking.. Thanks for a second opinion seems very similar to xoom. Shame how host cant produce 5v at 500ma it wouldnt be to hard for them to up the lousy 3.7v it seems they are running now

[Q] Nexus Media Importer help!

Hi Guys,
I bought a Noosy U-disk (4 gb of space + acts as a microSD card reader) for my N10 and I'm disappointed that nexus media importer doesn't do anything when I plug it in. It just says "connecting......waiting for media" and I can never access the files on it.
I bought this thing b/c of it's potential utility with it's microUSB on one side + USB/Card reader on the other. I am desperate to get this working since I am constantly on the run in the hospital and need fast access to my notes & guidelines without eating up all my storage. I'm not interested in rooting b/c I have it set up perfectly and don't want to redo all that redownloading of apps etc...and I don't know what I'm doing lol.
It works PERFECTLY with my Galaxy S3, however.
Thanks and I really appreciate it.
(Note: I also bought a couple of OTG cables but they are taking FOREVER to arrive since they are coming from China)
attached is a pic of my U-disk

Hi there sa278. First of all, if it's working with the samsung galaxy S3, we can all guess where is the problem. However, if you want to root your device, there's a method that won't erase your data, and it is automatically, fast and accurate. Look in the forum for superboot, you just need to install the drivers, and double click a .bat file, the rest is up to the program.
I have to say that nexus media importer will let you use the permission of "write" (plus the ones that you have on non-rooted) by rooting your device, but that's not necessary in your case (non-rooted device can only read and execute).
You can give it a try, but it's pretty weird. Have you tried with any other usb? Goodluck!
Sorry for my english

The developer for NMI is very responsive if you email him. I bought the same U-disk device and could only get the built in drive to work, not the card reader. The developer and I emailed for several days and tried to get it to work. Rooting won't help you get the u-disk to work. We tried that as well. I ended up buying a micro-usb microsd card reader instead from aliexpress that works perfectly with NMI.

Do you mind posting a link to the micro-usb microSD card reader you are currently using from aliexpress? I was really hoping this U-disk would work...how disappointing
Thank you.

No problem. This solved my problem of storing movies on my Nexus 10. This is the link: http://www.aliexpress.com/item/USB-OTG-Connection-Kit-MicroB-MicroSD-Card-Reader-for-Cellphone-PC-Smartphone-free-shipping/701881177.html. It works perfectly and is small enough not to interfere with the headphone jack.

Not working anymore
I just recently got NMI for my Nexus 7 and using my OTG cable i was able to use my Seagate 1tB external to view movies and music but now when i connect it i keep getting a Connecting USB Device /dev/bus/usb/002/002 Waiting for Media that lasts forever...any ideas?

OTG - Is it possible? - Yes it is

Well I know its been talked about in the other threads of the possibilities. So now since we have the devices here, are proceeding with unlocking and rooting the devices. Has anyone had luck?
Sadly I do not have a OTG cable yet to test this but at least wanted to start somewhere.
Edit: Yes it is, see post below for link. Device needs to be rooted for it to work!

Says he was able, after root, to mount 2 drives simultaneously.

Brilliant! Thanks

Has anyone try this:

It doesn't require root so it should be good for stock users.

I can confirm a stock non rooted N7 I threw in a USB flash drive and read files and played a movie real quick earlier just to see if it all worked, didn't try much more then that but can try some more tomorrow. Still busy transferring and reinstalling apps from old N7.

I cannot get Nexus Media Importer to work on stock. It reports all memory sticks as protected.

I have a non rooted stock nexus 7 2013. The media importer doesn't work for me also.

Now rooted using Stickmount, still not working. The drive can be seen but it seems only small files can be viewed, and you can't copy them or do anything with them. Non of my, larger, movie files show up.

I was able to copy a 3GB movie file from a flashdrive to the onboard memory with no issues. Maybe try a powered USB hub? I didn't have to in this case but it might help.
I tried to read an external hard drive and had to use a powered USB hub to even have it mount. Alas, couldn't read anything. Don't know if it's because the hard drive was formatted NTFS or because it was 750GB.

USB OTG Helper works for me. It also supports NTFS drives.

Can anyone tell if it's possible to to use OTG while wireless charging the device?
Need this for my car dashboard tablet replacement.

I think the problem with that would be that it would drain after than it charges. Qi charging doesn't have great amperage.

works for me as well, I am wondering if there will be a root flash-able mod like the original N7 had to turn OTG on.

Why does Google not allow OTG to be active out of box? Is the lure of trying force people into using the cloud that strong? Clouds drain more battery compared to local content and wifi connections do not have 100% coverage like local does.
The reality is the reason this device is priced at near break-even pricing IS the cloud, so this is why there is no SD slot or full OTG, out of box. Most people do not mod, so most people will be part of their cloud control strategy. I would rather pay $50 more and let Google make a profit on the device, that way I could have a micro sd slot and OTG out of box. Curse Google and their quest for content control and data mining! :silly:

Earlier I said it wasn't working, without knowingly changing anything both Stickmount and Nexus Media Importer now work. I am rooted and perhaps Stickmount is making NMI work.

Stick Mount works 100% fine for me, just watched a movie from my thumb drive. I am stock+Root. Open file system and on SD card look at the USB Storage folder if you are unfamiliar with Stick Root.

Is otg ok with usb pen drive or 2.5 hard disk without power supply?

Yes and I also used it with a USB External HD and it worked fine there, too.

I had issues with OTG on my first N7 2013. It was a flaky connection and would go into a connect/disconnect loop and then just stop all together. I returned it and picked up a different. That one seems to work fine.
Stock, not rooted, and using Nexus Media Importer.
Some people may want to try rebooting their N7 as well.... If you look at the NMI app in the Play Store the developer knows there are a few issues with Android 4.3 when first using the app.

GPD XD OTG Issues

Hello everyone, I hope this is the right section where to post, I have scrolled down the home page until I've found this one. This is an android console based on Rockchip cpu so I guessed I'd give it a try with my problem. If not please forgive my dumbness and move the thread.
I have bought a GPD XD console that works very flawlessly beside one big huge damn problem I am not able to resolve.
One day I tried to hook it to my TV and looks great. Then I wanted to connect my 360 wired controller via USB otg. No luck. Then I tried ps3. Same. Ps4 controller? Again nothing appears on screen. Mouse, keyboards, flash drives, just nothing. Also updated it to last firmware. Tried 3 usb otg cables, 2 cheap one and one with gold plated connectors that costs more (dunno if this changes).
So I tried some of the methods I've found online to test the otg support and actually otg support is ok. What wasn't ok therefore, is that I had to download 3 xml files and putting then into permissions folder and allow them but still nothing happens. Downloaded then a vold file to put it into etc folder and again nothing works. The apps i've tried all tells me the otg support is ok but find me no otg signal
Actually usb port works for charging the device or make it visible to pc but this damn otg won't work.
I tried almost anything, . I am kinda noob at this but if usb works for charging and pc I can assume is a software issue and not an hardware one, or is it possibile the otg function depends on usb port "broken" even if usb port works for other operations?
Please I would be very glad if you could help me. Since it's passed too much time for a refund and send it back in China for a replacement will costs me a lot and takes like months if not one year as I've read around.
