This is actually using MTP, connecting as a mass storage device on Linux could require additional steps. MTP support on Linux ain't that good (IMHO)

Charging it using standard USB 5v is not feasible. That would burn USB port

I have a Samsung 42" plasma with USB port and it read my HDD and all my thumb-drives to play movies/Pics/musics. Never thought of trying with my Defy. Will certainly try this out today.
If the device supports mass storage host protocol then I dont see as to why it wont. My LCD recognises the defy without a problem.

well yes normal usb sicks do work. hmmm i will test it some more.
If this is possible it would be very useful. I could put a bookable ubuntu on my phone and boot pc's from that instead of carrying a pendrive everywhere.

hmm.... maybe just a little disclaimer in case it needs to be said: when enabling USB mass storage, the only storage system that can be seen from the defy is the one on the micro SD card.
So, if you don't have one, i'm pretty sure nothing would happen even if you connect it properly

There might be some issue in the device u are trying to connect to. Even in my pc i have usb issues. Some specific pen drives just randomly wont work on my pc. Just my 2 cents.
I have been very excited about the GN since it was announced. I love the big screen and the fact that it is a pure Android phone.
There has been a lot of talk about the lack of Mass Storage on the GN, but I am not sure I care. I don't really understand what happens with MTP. So I have some questions that perhaps those familiar can fill me in on.
When you plug the phone into a Windows PC, what happens?
-Can I still drag music over to the phone or do I have to use some kind of a wizard?
-I will ONLY be able to copy over music, videos and pictures correct? I can't copy other data over, for example a ROM via USB right?
- I can still copy things like ROMs over using a file manager and WiFi correct?
Thanks!

Provided that the Windows PC is Windows XP + WMP10 or above, it'll function very similarily to a normal drive, except you will just see it as "Galaxy Nexus" instead of being represented with a drive letter.
You can copy anything you desire, only PTP has a restriction of accessing the camera/picture folders.
It is said that transferring larger files or a bigger queue of files may lead to freezing or cancelled transfers, but i've personally not experienced that yet(On my Eee Pad Transformer)

Thanks! So if that is the case, why all the talk that people are disappointed that Mass Storage support is not there? If it still appears and you can still copy files over, what is the problem? Do people really want a drive letter that badly? For what? Scripting of some soft?
How does this affect mounting the phone under Linux?
With my current phone, I plug it in and since it is a mass storage device Fedora simply assigns it as a hard drive /dev/sdb for example. I can then just mount the SD card inside the phone.
Is this going to cause a major headache for me? I'm switching to a Linux phone to get away from all this Windows crap!

Actually MTP is not without it's drawbacks, due to the "lack of a drive letter", or rather it being considered a physical drive, it also means that interoperability will be harder to achieve.
This would especially be true for devices like car radios with USB support, traditionally you would be able to simply connect your phone and let it serve as a USB thumb drive, the car radio could then play music from the phone, but that won't be possible due to MTP, further more since the phone is not a drive, a program that for example does not use the windows explorer as a way to copy those files would have no concept of the drive, for example, a command prompt wouldn't be able to access the drive as it has no drive mapping.
There are other pros and cons, but i think this is the one people are the most concerned about.

Google has official support for MTP on Mac, as for Linux the community already has support for it as well, i don't use either system so i can't go into more detail, i just know that the support is there

If you're referring to a mod that enables USB Mass Storage mode on the Galaxy Nexus, there likely won't be since the storage on the Galaxy Nexus is partitioned in a completely different manner to how has been done previously on Android phones.

Considering how Dan Morrill explains why the Galaxy Nexus has no USB Mass Storage support I certainly wouldn't want to try it

Using your own bootloader/recovery there's nothing preventing you from repartitioning the Galaxy Nexus the same way how Android systems used to be partitioned before Honeycomb, i.e. with a separate FAT32 internal partition for media storage. You just have to be aware of the tradeoffs: with a separate media partition, you have USB mass storage but you'll have to manage two separate partitions for apps and media with two separate space constraints. With a unified partition you just have one constraint, but you lose the USB mass storage capability.

Indeed..
*this* is why I got a Nexus Something not right.. wait a couple of hours and there'll be a fix on XDA..
Sorry, but the Nexus is a pile if I can't use it as a DAP source for my car audio. Is there any possible way to enable USB mass storage? This device will have far too many compromises to be even usable if mass storage isn't present.

Which built-in or OEM car infotainment systems support MTP?
Supposedly Ford cars with SYNC 1.0/2.0 support MTP. Windows Embedded Automotive 7 supports MTP, which is used in the MY2012+ MyFord/MyLincoln Touch systems, Nissan Leaf, Fiat 500, and some Kia models (may go under the "Uvo" system name). Alpine may use WEA7 at some point, maybe in a built-in or OEM nav system that might have a USB port that would work with the Galaxy Nexus, but I haven't found any model numbers yet. There have also been rumors that some upcoming cars (Tesla Model S, maybe?) will use Android for their infotainment systems, but nothing specific, and that doesn't guarantee MTP support.
One article mentioned using Bluetooth instead, but I'm not sure how that would work with the car's built-in Bluetooth. Possibly means pairing with a portable Garmin/TomTom nav device that supports Bluetooth A2DP, though higher end portable nav devices have flash storage for music files and can play music directly.
There are also several aftermarket head units that support MTP. Alpine, Sony, and Kenwood have some, I believe, and there may be others.
EDIT: As far as built-in goes, I think BMW has supported MTP devices on their stock audio systems for at least 3-4 years. I haven't looked at Audi or some of the better Japanese/Korean makes/models, but wouldn't surprise me if some of them did as well.
This is not the same.
This is USB host functionality, where GN can access external usb disk attached to it.
What we are talking here is GN attached to something an recognized as usb disk.

Well, doesn't clockworkmod recovery already allow you to repartition your storage the way you want?
And since the OS does actually support usb mass storage, it should be fairly easy to create a FAT32 partition for sd card usage. (Similar to Nexus S, which has no sd card slot but comes with 2 partitions: 1 GB internal storage apps, 15 GB for usb storage)
Hi,
In january/february, i bought a USB keyboard with an USB adaptater to use it with my tablet.
I tried to plug it in the 3G's usb port, it did'nt worked, and because last week I broken it, and I updated my tab to ICS, I tried to plug my keyboard in the 3G port, and it worked !
Maybe it's because of ICS ?
Also, my keyboard has also an usb hub, it works too !
Mine seemed to work from the the start with Rom version: 3.2.69 and that's on 2 different G9 101, however others result have varied and it seems a bit hit and miss to say exactly what's going on.
I know there are 2 different versions of the 10" G9 - A101S and A101H , I've not dug too deep into it and I'm not 100% and what the differences are.
I think ICS generally improved the Usb Host support/integration which is always welcome.
Now I just need a large bag to transfer all these extra devices for my "portable tablet".
Mine won't see USB drives/camera cards formatted to FAT32. No big deal.
Actually, it did connect with my phone and its 16GB microSD card, so I'm happily mistaken.
From the ICS "firmware" update change log:
Archos 80/101 G9
Firmware changes
Version 4.0.4 - March 8th, 2012
Initial Ice Cream Sandwich 4.0.3 firmware release
MediaCenter Video: support for MKV3D on TV with automatic switch to best 3D mode
MediaCenter Video: allow to disable system notifications in video player
MediaCenter Video: collection of VOB files from DVD are now gathered into a single movie item
MediaCenter Music: integrate Music control panel in Lock Screen
MediaCenter info dialog: allow to edit the name used for performing the Movie and TVShow online search
File Manager: display a notification when file copy continues in background
File Manager: improved drag and drop support
File Manager: new option to prevent indexing of some storage/sdcard folders by multimedia library
Applications: more robust video conferencing support (Google talk, Skype etc.)
USB file transfer: a samba server is now activated on the tablet when using USB network tethering for easier file transfer on non Windows based hosts [Samba for "non Windows"??? Something bass-ackwards about that ...]
Archos widgets: new USB network tether widget [Anyone know if this means it will tether off a phone this way ala older Archos models like the 5 or 43 , or is this meant to "share" its internet connection (however it would obtain it, even if not "3G-enabled" - which seems useless)]
External Keyboard: french layout has been expanded to handle AtlGr keys for special symbols
Accessories: Xbox gamepad support
Maybe I shoulda hung on to the new 80 I bought a week ago, and returned after trying it out for a few days. The inability to get the back/3G USB port and MTP tools to work was a big factor in my return decision (along with no network tether option as the 5 and 43 had, and the reality check on the initial Staples web page claiming 1GB RAM - hope springs eternal...)
FWIW,
R
@rokkywoof I think that it's for the micro usb port, because this oen is meant to be an OTG micro usb port, and the original usb port is just for the 3G, but maybe they failed and applied the stuff to the 3G's port?
@Telyx/trevd wow that's strange !
I saw that the A80S (A101S) are the archos with flash memory (8 or 16gb), and the A80H/A101H are the archos with the Hard drive (H for Hard drive )

Is this true? This is the main reason why I was planning on getting this tablet this week because it is (or so I thought) that would have been able to transfer raw files from my CF cards to the internal hd, and backed up on an external HD. I shoot about 300gig a week while on the road.

It works fine... just have to turn on the "3G Stick" port, then wait a moment before plugging the camera, phone, thumb drive, card reader, etc. in. One camera connects like a thumb drive (mount the "drive" manually and open the folder in the file explorer), the other launches the Gallery app to allow me to import pictures.

3G's USB seems to work with nearly Everything
Hi @ll,
I also tried to get USB devices to work, no problem with USB-Sticks, but USB-HDD's (selfpowered) seem not to Work (neither on Stock image nor on Cyanogenmod). The HDD starts turning but Android doesn't mount it. Can someone give me some pointers?
My Specs:
Archos G9 80 Turbo HDD with an USB-HDD (USB 3.0 (should be backwards compatible)) by Toshiba
Thanks
I would bet the tablet is not able to supply enough power to actually start the USB HD up.
Remember that usb port was designed to be used with Archos' 3G cell stick and really wasn't meant to be hooked up to other things.
If the port is enabled, there is allways power for the hdd, also for a stick a mouse. But some keybords may not work (I don't figure it out).
The app USB OTG Helper will help to mount the hdd/stick.
I used a friends powered usb hub (dlink dub-h7) and was able to use both my keyboard and mouse with my tablet unfortunately my usb thumb drives dont work when attached to the usb hub however they do work when attached to the hub I didnt have my powered usb hard drive with me to test

There are no devices that use mass storage anymore since like 4.1.2. Everything has switched to MTP. This is everywhere on the internet and id bet on XDA.

I've found the USB Mass Storage handy for specific items and recently I was trying to recover some files (Via Android Restore program) that only worked if there was a USB Storage option, MTP wouldn't work. I have tried some apps on the app store, but none of them work to activate USB Storage. Was hoping their was a work around

Not sure how connecting a pendrive (otg or not, and btw it is very likely that the the microusb port on the pen-drive is also otg ) does not violate the above the same. When the note 8 acting as a Usb mass Storage Media is the main concern.
now back to topic,
Like it or not of companies have decided to do away with UMS. It basically boils down to architecture issues with their future plans.
UMS Gives exclusive access to the HOST (your computer or what ever you connect your device as Media to) and thus android/phone has to unmount the volume to prevent any locks or other potential issues (which are many including security).
Also the Host (your computer) has to be able to read/write the Files System format that you phone/ sd card is formatted to. (it's a dependency, because if the tablet where to use/ invent some new native file system, a lot of existing hosts might not be able to read them at all.
There are other reasons too like singular large ultra fast storage blocks to act as file systems as well RAM which can break if requiring unmounting,
Now MTP is not god send either and has it's own set of issues (read below)
however it's evolving.
with MTP most of the control is with your tablet or phone. and data is not written to the media directly by the host in for form for Blocks, but rather as files etc and thus the slowness as speed also depends a lot on your device not to mention it's biggest drawback that it's sequential/synchronous.
Personally, If i need to do large transfers etc, I just remove my microsd card in put that it into a tiny card reader, not ideal but works.
It is very unlikely that we are going to be getting UMS officially from those who are done with the standard on similar devices, . Maybe some better alternative in future than MTP, but who knows.
Here is little extract from the wiki : http://en.wikipedia.org/wiki/Media_Transfer_Protocol
for who care about the how's and the why's
History
The main purpose of this protocol is to allow only the transfer of media files and associated metadata to and from portable devices, one transfer function, in or out, at a time. Productivity functions such as open, edit and modify require copying to the hosting system for these functions then copied back in their entirety to change the data.
The protocol was originally implemented for use across USB but extended for use across TCP/IP and Bluetooth. Windows Vista supports MTP over TCP/IP. Windows 7 and Windows Vista with the Platform Update for Windows Vista also support MTP over Bluetooth.[7] The host connecting to an MTP device is called an MTP Initiator whereas the device itself is an MTP Responder.[8]
A main reason for using MTP rather than, for example, the USB mass-storage device class (MSC) is that the latter operates at the granularity of a mass storage device block (usually in practice, a FAT block), rather than at the logical file level. In other words, the USB mass storage class is designed to give a host computer undifferentiated access to bulk mass storage, such as compact flash, rather than to a file system, which might be safely shared with the target device (except for specific files which the host might be modifying/accessing). In practice, therefore, when a USB host computer has mounted an MSC partition, it assumes absolute control of the storage, which then may not be safely modified by the device without risk of data corruption until the host computer has severed the connection. Furthermore, because the host computer has full control over the connected storage device, there is a risk that the host computer may corrupt the file system, reformat it to a file system not supported by the USB device, or otherwise modify it in such a way that the USB device cannot completely understand it.
MTP and PTP specifically overcome this issue by making the unit of managed storage a local file rather than an entire (possibly very large) unit of mass storage at the block level. In this way, MTP works like a transactional file system - either the entire file is written/read or nothing. The storage media is not affected by failed transfers.
In case the device maintains a database/index of the content of the disk, MTP saves the cost of re-scanning the entire disk every time the content is modified.
Additionally, the MTP allows MTP Initiators to identify the specific capabilities of device(s) with respect to file formats and functionality. In particular, MTP Initiators may have to provide passwords and other information to unlock files, or otherwise enable digital rights management. Nothing specific of this nature is in the core standard but the features are available via vendor extensions. MTPZ, the Zune Extension to MTP specifically denies access to files until authentication has been processed, which is only possible using Windows Media Player 10 or higher.
Drawbacks
No multitasking - Unlike USB mass storage, MTP has been built to only allow a single function at a time, e.g. read, write, delete, with no other function available until the first function is complete.
By design, MTP devices (like PTP devices) are not treated as a traditional removable drive. The actual file system is implemented by the device, not by the computer's operating system. In theory the operating system may hide this difference, but this is not the case on Windows or Mac OS.[clarification needed] This also means that file system recovery tools on the computer will be of no use if the drive is corrupted, or crashes.
As of 2013, MTP is much less widely-supported than USB Mass Storage (see support section).
The MTP and PTP standards do not support direct modification of objects. Modified objects must be copied out of the device and reuploaded in their entirety, which can take a long time for large objects.
Google's MTP implementation in Android includes extensions to deal with this limitation.[9][10]
Windows/PC MTP implementation:
When opening a file, the user must wait till the file has copied to the PC before it can be viewed. (Note: The file remains on the PC hard drive after viewing and the device is removed)
No creation of files on the device from the PC, files must be created on the PC and copied over.
No editing of files on the device, files must be copied off the device before edits can be saved and file copied back.

As a workaround, for PC users at least, there is a Total Commander plugin which displays the MTP folders in normal file panel. It does not provide all the UMS features, like say binary directory sync (lack of which is one of my biggest griefs with MTP), but it's useful for simple file operations (browsing, copying etc.)
If anyone's interested I'll try to find the link/instructions.

Sorry.. Wrong thread

There are no devices that use mass storage anymore since like 4.1.2. Everything has switched to MTP. This is everywhere on the internet and id bet on XDA.

And I can tell you, my brother is SERIOUSLY pissed. He's all ready to go smack around a few people at Google for this (once he's done smacking a LOT of people at Microsoft, now that his new machine is saddled with MSWin8).
In truth, it seems very arrogant on Google's part to presume that no one would want/need to use USB storage mode. My brother would like to edit files on the Note8 while it's attached to teh computer (using LibreOffice on the computer to edit it), and he feels it's absolutely preposterous that he has to copy the file down, edit it, then copy it back up. Google, 1985 wants it's broken methodology back.

I haven't yet had a reason to check if the Note will work, but does work on a Galaxy3 with Cyanogenmod. It goes and mangles the drivers to support the depreciated mass-storage proto. Expect it to be hit-and-miss when changing roms, requires root, requires kernel to no have completely disabled the old drivers. I now carry a recovery cdrom on my phone, it's worked most of the time.
So honestly I really don't know what happened but my LCD is cracked- rending my phone more or less useless. I have just transferred my internal memory to my PC via USB, but I don't know if my text messages are included in that/what the file name is if it was part of my internal memory. Thoughts or suggestions? I have tried downloading a mirroring program but I need to log in on my device, and as I cant use the device.... well that's pretty self explanatory.
You Need a OTG Cable (Micro USB OTG to USB 2.0 Adapter)

Since no one answered I will post what I did to get my information back.
My screen was unusable (touch wise) but I could see it fine. I bought one of these adapters

I plugged a USB mouse into this cable and a usb cursor appeared on my screen, allowing me to unlock my phone and operate it with the mouse, so I was able to back up whatever info I needed and transferred it via wifi to my new phone.
