[Q] What's the micro usb port for?

Does anyone use the micro usb port? I have yet to find a use for it. I can't transfer files with it, charge with it nor are there any peripherals (that I know of) that can use it. I searched around but couldn't find much useful stuff on the port. All I found was this useless video:
**Ok I can't post the video because of more stupid forum rules but just go to youtube.com and append this after the url: /watch?v=1xBVu-IatDQ **
Anyway, if someone has ideas on how this port can be used I'm all ears... Thanks.

It is a file transfer port. you plug a cable into it and into your PCs usb port. works like the ones on your phone.

Does it work for you? Because it doesn't for me. Nothing happens when I plug it into a computer. No automounting on the computer side or indication on the tablet that I can put it into "usb storage mode" like the 2.X Android versions do.

What OS are you using on your computer, and have you installed the drivers for it?

Computer OS? i just plugged it into my Win7 system and it was there instantly. 3.0 shows up as a media device, which allows both the tablet and the computer to talk to the sdcard at the same time. So you won't see a mount prompt on the tablet. BTW my Incredible2 is running 2.3 and also lets me access the SD card on it and the computer at the same time.

I'm still using an old tiny xp and it worked fine for me just plugged it in and there it was

I tried Gentoo Linux and XP and neither worked. What drivers do I need to install?
I also have access to a Win7 system so I'll try that.
dq

Drivers from acer website.

I have adb installed should this not be enough?

You need none installed. ADB if its running in some form might be interfering. its just a basic driver in windows it uses.

I only run adb-server when I need it and not all the time. I thought that any needed drivers would have been installed when I installed adb.
For my Gentoo machine what should I do? It's not detected at all if I plug it in. My x10 mini and Nexus One are detected no problem and I can mount them and everything so what's up? Is there a kernel module that I need to build?
Thanks.

I had to download these drivers for my xp netbook ,,

I agree with Nova 5. The Windows drivers for USB come with the SDK and while you might not think you will have use for the SDK you will. It makes the process of installing custom ROM,s and Recovery Kernels a breeze. You download your zip flashes or recovery images to Win 7 and then you adb push your downloads to the tablet. The alternatives, unless soneone was nice enough to compile you an apk, which most advanced system developers don,t bother with, unless their app is destined for the massees throug Andriod market, is to install a terminal emulator and enter native Unix/Linux shell commands manually. If you aren't a shell cmd expert I suggest you immediatly download the latest Android SDK for Windows and start learning what it can do for you with just 2 or 3 adb push commands which can help you advoid 10's of lines of manually entered Linux shell commands that can do some real damage to your system if you are copying someone elses terminal emulator sh install instructions, don't understand what they do and make 1 simple typing mistake. With adb push you don't even have to get involved in Linux's complicated bit based permission changes to install something at the system level.

Yes, well I only really use adb in the same capacity as what you describe-- to root a device. After that busybox can be installed and I can either ssh into the device (which I prefer) or use the terminal on the device itself.
But my problem is the detection of the device once it is plugged into my Linux box. I'm not sure if I need a special driver for that and I'd rather not aimlessly search through the kernel config in order to build one (I've done that before and it's painful!). It's good to know that one can mount it on an external device and still use it simultaneously though. That will save me time in trying to fiddle around with settings in the tablet itself...

If you are not able to transfer files Try enabling usb debugging before connecting to pc.

If the tab is not in the usb devices list and it doesn't show up as an unknown device, you might want to try another usb cable. Or another port if you have the Windows and Linux on the same machine and you are trying to connect on the same port.

Not nearly what I was saying. Not even close enough that a bomb would touch it.
Simple answer is my vista and win7 systems accessed the iconia as a media player device requiring no drivers as they are a common system driver. My only comment about ADB was that it might be interfering if it somehow was left running in the background.

I'm not sure what the problem is, but I had to play around with the settings and plug it in several times and finally it showed up. Now I plug it in and the dialog for auto play shows up instantly. When I choose to view files, I get a window with two drives. One is the internal storage and the other is the sd card.

Sometimes mine gets a bit wonky as well. Every now and then, I'll plug it in, get the windows dialogue box asking me what I want to do. I open it up and the box is blank, no drives, nothing. Unplug it, wait a few seconds, pop it back in, and everything is OK. No rhyme or reason, and it doesn't happen all the time.

Quick trick for win7 .
Plug in the device.go into device manager delete its entry and the USB controller it resides on.unplug device.install driver from acer web site.then try the device again.
This works on several USB type issues
Good luck if you don't understand don't try

Cannot transfer files with MTP / Device not viewable in Windows Explorer

When I connect my Nexus 7 to my Windows XP (SP3) PC via USB, it's obvious the computer recognizes it and it tries to install ADB drivers. Whether I choose to install those drivers or not, I still can't locate my device in the Windows Explorer Tree. I checked Disk Management for the hell of it and nothing but my PC's harddrives were there. There's an attempt to install drivers for "MTP" but that fails and I'm pretty sure that's the cause; however, I'm unable to replicate it, even as I uninstall/reinstall applicable drivers from the device manager the MTP failure never happens anymore. I did some googling and found a thread with someone who had a similiar experience. In turn, I downloaded https://www.box.com/s/2c25e8bc42ecce400afd to try a different set of drivers. Same problem. Driver install is fine for ADB, but still unable to see my device in Windows Explorer. I'm able to successfully connect the device to the PC with PTP for the camera. I can access DCIM and cache which can serve as a work around, but I'm hoping you can provide any ideas you might have. Thank you!
edit - ***resolution***: Ok, I figured it out...I had to disable USB debugging. I don't know if this helped either, but I installed these drivers as an alternative to the drivers that were originally installed: https://www.box.com/s/2c25e8bc42ecce400afd
While connected to PC, I switched to PTP mode because I was about to give up and just use that
I then disabled usb debugging and switched back to MTP at which point the drivers successfully installed and I could now view my device in Windows Explorer. I also believe downloading the drivers in the link above helped since the first crack I took at this was unsuccessful with existing drivers.

install pdanet on pc and it will install drivers for u so it will be recognized

Been battling with this on my XP machine since yesterday. I couldn't even get debugging to work until I installed NakedDriver. And even still, there seems to be no way to get MTP to work without turning debugging off. On my Win7 machine everything worked perfectly, both ADB and MTP, right out of the box. I have the Galaxy Nexus drivers installed on both machines (which I've read are compatible with the N7). I also have the latest version of Windows Media Player (I've read that some older versions have issues with MTP). Is anyone else able to run ADB and MTP on XP?
*edit*
A: Does PDAnet let you use MTP and ADB simultaneously? Because I really don't want to install it if I don't have to. I got rid of it ages ago (too many things starting up at boot time).
B: I have a Galaxy Nexus also, and I have no issues on the XP box.

I wouldn't bother with MTP, it's not always showing the contents of the internal storage properly when viewed in Windows Explorer.
Earlier today when I was trying to set up a backup profile for it, it didn't copy all the files off. On closer inspection I found folders like TitaniumBackup to be completely empty, which is not true according to ES File Explorer on the tablet.
I tried connecting MTP again, with USB Debugging on and off but this made no difference. Also I'm only seeing the Notifications folder instead of 36 folders on the internal storage now, really random how it's working.

Same here. No change with the Asus drivers. Still can't use MTP when ADB is turned on.

poo. how do I transfer my audiobooks to this stupid device without working drivers?

1. Please disconnect Nexus7
2. Remove drivers on PC.
3. Toggle ON : Settings->Wireless&Networkings->More->NFC.
4. Re-connect device
Good luck !

1. Uncheck MTP, check the one next to it (Camera)
2. Unplug USB
3. Turn off USB Debugging (Uncheck it)
4. Plug in USB
5. Should say connected as camera, then a new window will pop-up allowing you to see your files.
Tell me if it works!

im having trouble too, is there any way to make the device to be recognised as a flash drive?

Same observation here (a few months later) on stock Android 4.1.1 rooted.
It seems that new files in the internal memory remain invisible for a long time, but so far they have become visible eventually, sometimes a day or two later. I have no clue what could possibly cause this, and I have not found any trick or workaround that makes them visible, not even rebooting. Any hint is welcome.

Didn't work. Just shows up as a camera with the limited folder access one would expect.

Workaround
I now use the following workaround.
Install SDrescan from Google Play.
Run it.
If you already had your phone connected to a computer as a media device (MTP) and are watching the contents of your SD card or internal memory in Windows Explorer, press F5 to refresh your view. If not, connect it now.
I'd be curious whether this works for you as well. If it does, press the THANKS button below.

Same issue with an old ibm x40 udated to windows xp pro SP3.
I've installed mtp driver, without success
I've "tried" to install asus driver, without success
I've tried to do as above with the help of the nexus toolkit, without success.
Everytime, the laptop recognize the device as android ADB interface.
Someone could help me?

MTP on Ubuntu/Mint/Debian

With many devices not supporting mass storage anymore Android seemed to have moved from mass storage to PTP and MTP
With Windows supporting MTP by default and Mac OSX with an application there isn't any native support in Linux.
There are a few work arounds like gMTP but that didn't really work for me.
There also is another work around that requires you to edit some files.
To make it easier for others I wrote a little bash script, that does most for you.
Step 1 : sudo apt-get install mtp-tools mtpfs
Step 2 : Plugin your device
Step 3 : Open up a terminal
Step 4 : Type in : “mtp-detect”
Step 5 : Write the PID and VID down, you will need this later
Step 6 : disconnect your device
Step 7 : Download the script and execute it by sudo ./mtp (don't forget to make it an executable first)
Step 8: Follow the instructions on screen and after it's done reboot and plugin your device
Step 9: Use the command "android-connect" to mount your device and "android-disconnect" to dismount
It's not much, but I hope it helped someone.
Please let me know if it worked for your device/distro.
Original post
Tested and working on the P3110 and P5110.
EDIT 1:
(First) time mount can take up to 1-2 minutes, have had where it would mount in a few seconds, others half a minute. Be patient.

Thanks for this. I think I have tried all this before and it has not worked, but will try again. A few things come to mind though. First, I think you have to turn USB debugging off, right? There is another thread where several of us are able to see the tablet, but not really get any files. Also there is a way to get the tablet to share PTP or MTP and that changes things too (PTP lets me see the top level but no subdirectories).
Will report back if this works or not.

I think USB debugging has to be on, at least for my phone. Mine is always on on all my devices.
Yeah you can see it in the file manager (1 for each SD card) with MTP but you can't access the files.
I am not sure about the PTP.. However for the MTP I just made a new folder in on my other SD card named extSD since MTP shows all directories of both sdcards in one directory.

Nope doesn't work with or without USB debug. I think the issue may be due to some problem with mtp-tools on 64 bit Linux. Are you running 32?
The mtpfs mounts but any attempt to list the mounted directory just hangs.

I am using 64bit, did you do the reboot and android-connect? If you are using nautilus you wont see your device under "Devices". You will see it above your filesystem.
Can you tell me what isn't working?

Well I'm using Kubuntu so no Nautilus. And I'm just looking at the mount point. My udev rules already have an entry for the mtd device. I also grabbed the latest libmtd and built it from source.
The fuse mount seems to work but any ls on the mount point just hangs forever.
Very strange.

At times like this I miss ubuntu
On my Arch (+XFCE), I use gMTP (uses mtpfs ofcourse). Most of the times it works, and then there are times when it is a pain in the a##. Gets stuck, does not respond, fails to copy what not.
I find the only reliable way is using adb.
Gosh! I push and pull everytime! :silly:

yeah, after a couple of days I found it not very stable at all, so I too switched over to ADB, it's not the fastest method. But we gotta get around, don't we?

I am also waiting for a permanent fix... Just switched back to Ubuntu from Windows 8 Preview, and I love it!!!
The only issue I have at the moment is the fact that I cannot connect directly to the PC from the Tab, although transfer speeds are better by removing the memory card and inserting it into the computer directly. Would be nice to use Rhythmbox to manage my MP3s.
I've tried a few solutions and nothing seems to work fully. I'll give the ideas mentioned above a try.

I have found my peace finally with qtADB.
By far the fastest, and most efficient app for this job.

Hello, this worked greatly on my ubuntu machine. Would this work on an ArchLinux headless PC? I'm willing to try it out if this doesn't mess anything up.

I can confirm this does not work on virtual box not sure on vmware as i dont have it so idk.

[email protected]:~$ android-connect
fuse: bad mount point `/media/GT-P3100': Transport endpoint is not connected

As you can see above, i tried this for P3100. Can someone tell me what am i doing wrong here? I really want to handle my device from Ubuntu 12.04.

hi there,
in newer kernel - at this thime for example debain testing jessie - is kio-mtp implemented. this compinent load your nexus 4 mtp device autmotically like in windows. can access device via filemenager without doing steps in console before. in long time support distribution - example debian stable wheezy - this is not implemented yet. you can compile own your own to get this working
kio-mtp is for kde
gnome-vfs with mtp is for gnome

Works on Kali Linux with 3.14 kernel - HTC One with 4.4.3. Thanks a lot

Usb mounting in linux? [solved]

Hey guys,
I'm having a bit of an issue with my s4, in my efforts to fix it, I am transferring files to my laptop, I'm using LinuxMint Mate Edition but I get a "can not lock device" error. I can use my windows partition, and it works fine so no problems there, but was seeing if anyone knew how to mount as a hard drive? I've enabled usb debugging and no go.
Mtp shows 2 ipods/media players but no files inside.
Ptp shows a camera, but files are all "corrupted". (they are not, that's just what it's telling me.)
I can put them on windows then access via linux, but I'd like to be able to just boot linux instead of running around.
(my windows is jacked, after x minutes it starts giving up, hard drive is partitioned so linux isn't affected by bad sectors, runs perfectly).
So yeah, any assistance would be most appreciated
Thanks
***edit:
Figured it out.
1. Apparently the ports was iffy, cable had to be just right for data transfer. Switched ports.
2. Look up go-mptfs! Build it from source and you should be good to go for those older linux distros

Nexus file transfer tedious.

Hi all,
Of late i have been facing this issue of transferring media files from PC to my nexus 10. On connection, MyComputer just crawls and whenever it connects the file transfer bar shows virtually no progress. Even if the file is just a few MB. I also have 2 users on this tablet and on the other user the same thing happens. I have to do multiple restarts to fix this and multiple file transfers is not possible as the whole PC hangs and Windows Explorer crashes.
Any help will be appriciated.
PS. Windows 7 OS and stock N10 with 4.4.2

Hi,
While I can't help you with the Windows issue I can offer you a temporary solution! Which is using adb push.
To do as such please go to the Manta Help Thread and check how to set up adb and enable USB Debugging. From there you will now open a terminal in the folder you want to copy the files and type:
Code:
adb push *filename* /sdcard/
Now the file is in your Nexus 10, if you want to push many files, I suggest creating one folder with the files and pushing the folder itself.
Code:
adb push *foldername*/ /sdcard/
Hope this helps a little . I use it a lot since my Fedora can't recognise MTP hahaha .

Have you looked at the wifi file transfer apps? - I've never tried them because I'm rooted and use Sambadroid.
Re the transfer speed problem I've a vague recollection that a USB 1 device, like a keyboard will pull other usb 2 devices on the same hub down to usb1 speeds. Have you tried other usb sockets? Other things you can try are disabling USB Legacy Support and enabling AHCI in your BIOS.

You've had a few tangential suggestions, the ADB push being the fastest with the hardware and software you have currently.
I don't actually store files on my "PC" really as my source, I store them on a NAS and then pull them either to my PC or my other devices. This makes all my devices "stateless" as I find individual devices I'm moving around with ultimately break more often so I prefer the NAS route. My NAS is a Raspberry Pi running Rasbian with a 1TB USB hardd drive and a 64GB OTG flashdrive.
You can add to the other ideas:
Airdroid which runs a small web server on your Android device and you access the Android device from browser on PC and push files, at Wifi speeds.
run web server on your "PC" and then in Android just get them in a download app. My "PC" is Linux and its running Apache and I either SSH from the PC to the Android and then wget the file or use of the file download methods inside Android.
USB OTG stick which also serves to augment capacity, I get about 22MB/s from USB to inside N10
One other indirect thing, is when you do a full Android flash wipe it seems to reformat and speed up the filesystem better than if you've done an upgrade, although I never benchmarked it to know, just an impression.
