[Q] Usb host on the go

Is there native support for Usb Host (like Samsung GS2)?
PS: I read the FAQ,but I didn't fount any video showing a nexus plugged to a usb pen o other peripherals

this was actually pointed out many times
yes it is supported
it was even mentioned on the launch day event on stage

Here is an article that gives more info on it...
http://www.androidpolice.com/2011/1...behind-galaxy-nexus-lack-of-usb-mass-storage/

USN Mass storage no, but USB Host yes ???
I'm utterly confused. If you look at
http://www.reddit.com/r/Android/comments/mg14z/whoa_whoa_ics_doesnt_support_usb_mass_storage/
it seems that GN can't be mounted as USB drive to a computer - they replaced it with MTP. How come that USB Host works ??

Because this time your phone will be the host and not your PC. That the internal storage can't be connected as ums doesn't mean your phone can't play host for usb thumb drives. All the honeycomb tablets do that already and some of them also just use mtp, like the Galaxy Tab 10.1 I'm typing this from.

is it only your supposition? or you have already checked this?
as it says the link above:
"What we will probably do eventually is add an import/export concept to removable storage. So the Camera will always save to internal-16GB, and when you pop in an SD card (or insert a thumb drive on USB host devices) you can start a migration or import/export dialog."
Am I right that there is no ability to connect usb flash drives for now on this device? Sorry, English is not my native language so I could make a mistke while translate this.
Explain to me please. usb-host for usb flash devices present or not?
Thank you in advance.

Has anyone who has the phone ACTUALLY tried it?

It's strange that nobody who already own nexus from this forum didn't tried this function yet. only conjectures that "it must have usb-host".
meanwhile this is very important function for device that doesn't have micro SD support.=(

I think that it isn't samsung fault. GN have the same USB swith that Galaxy Note have. so the hardware is similar. I think the reason may be in new ICS (in that case I hope we will get host later) or in same that GN doesn't support usb mass storage (in that case we can forget about host).

My past 3 phones have been samsungs. I like the brand but I have this suspicion that they like to keep their better features for their own flagship phones. Not that I can blame them.
Would really appreciate it if anyone can confirm or deny if the otg works on browsing thumb drives.

It's neither.
ICS obviously supports it, as it was part of the sourcecode from hc and onwards.
And it cannot have anything to do with the way it connects to a pc, as that is nothing but a problem with the fact, that the storage for the pc and the storage for app-data is on the same partition, meaning that mounting this partition to a pc in ums would render the phone useless meanwhile.

No it doesn't but I think I know why, both of the drives are ntfs. Let me format them to fat 32 and try again.

You have to use a cable like this to test:

GN Mass Stroage / MTP

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.

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.

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)

[Q] Resize partition for USB Mass Storage?

Thinking about getting a VZW-branded GN. One of the biggest draw backs I have with it is the lack of USB Mass storage support. Is it possible to resize the internal 32GB memory to 16 or 24GB, and then create another partition that can be used for USB Mass Storage?

It basically acts as USB mass storage.. you plug it into your computer and you see all of the files. You can place files on it and remove just like you would USB mass storage

The problem is that MTP/PTP doesn't work for embedded devices and also most cars don't support them. That's why I'm trying to find a solution to make it work in normal USB Mass Storage mode instead.

It should be possible (take a look at the Blackrose thread in the Nexus One forum). Dla5244 and intersectRaven managed to do it for the N1, so it should be a similar process for the GN. It will take a custom bootloader.

We Need Custom ROMs with Mass Storage Mode Resurrected

I am so sick of MTP instead of Mass Storage Mode. I run Linux Mint and it's simply painful to try to get MTP working properly like Mass Storage Mode did in GB. Please, ROM devs, answer my prayers.

when you can add a sd card to the phone, you will have your mass storage.

I realize people don't like change, and want to stick with UMS, but you would have to pretty much crush the awesome single partition storage of the GN to get UMS...

Just dont understand why most people are aways want SOME MORE STOREGE, how many stuff you gonna put in your device? A thousand songs or pics?

With UMS enabled, they'd theoretically have lower storage than sticking with MTP. There would have to be at least 2 partitions that would mean files couldn't span across them.

I use wifi file explorer pro. Real easy and just as effective as having mass storage. Was bummed as far as me not being able to connect and drag/drop but when i found this app its just as good.

I can't for the life of me understand this complaint. I have no issues using MTP either in Linux or Win7. Do partition the space up would only bring about all the issues with inadequate space the Nexus One encountered.

I don't know if it's a MTP thing, but I'm having a hell of a time copying .mkv files to the phone. I can FTP to my Thinkpad Slate at 3MB/s via wifi, the GNex capps out at 400KB/s. I've tried to connect the phone via USB to my desktop and just drag and drop and the progress bar doesn't even move. This is driving me insane.
I'm using the latest GummyNex 0.6.6.
If I recall correctly, when I was using Android Revolution 2.1.2, it was copying at 2MB/s via wifi FTP. I guess I need to look into this.

Looks like it solves your needs without introducing the troubles of mass storage mode.

airdroid also works well (ubuntu 10.04 and 11.10 on different machines, also better than mtp on vista for me)

it's been 8 hours and my music is still copying to my phone. MTP is completely unacceptable. it's already told me i had to skip like 30 songs before i hit "skip this message" 2 hours ago. i'm copying ~25 GB of music over and half of that is .ogg which is not natively recognized by MTP. I could have copied the 25GB onto my thunderbolt 10 times over already. I dont care what the reasoning, requirement, or intent was to remove mass storage, but it was not work it. watching my files copy at like 400 k/s to a phone plugged in with a USB 2.0 cable makes me want to return the phone.

Drag and drop the files onto the folder icon. Don't open the folder itself and then copy into it.

My problem with MTP is compatibility. Hardly anything recognizes MTP and knows what to do with it besides my PC. Things I used to connect to via USB to transfer files or backup while on the go just don't work with the nexus. So instead of having an all around portable storage device in my phone I now have to carry other devices to perform those tasks, might not sound like a big deal but its just nicer being able to have that ability in one device. MTP may be great for some but not for everyone.

Agreed - my primary OS is linux, I can make mtp work kinda but it's poor and slow.
However enabling UMS would require repartitioning the GN and afaik no one's done it or said they plan on doing it.
Most people find wireless transfer much more satisfactory for this phone - I've only used airdroid but others have set up their own wireless ftp server. There are probably other apps that do it...

How do I enable mass storage?

I'm trying to connect my phone to my Father's Mini via usb, but the car does "see" the phone.
I've noticed that the check box for mass storage is greyed out and I cannot select it.
Does anyone have any good ideas for me to try out and get my gnex to connect?
For what it's worth, I'm using Liquid rom, and but my dad's HTC Desire HD running AOKP has the same problem, yet I have no problem connecting a BlackBerry.
Cheers.

your nexus will never have mass storage as the partition is 1 giant partition used by the system and used for storage.

You will never be able to use USB Mass Storage on the Galaxy Nexus. It uses MTP (Media Transfer Protocol) and PTP (Picture Transfer Protocol) to xfer files between the phone and a PC.
The reason why they use this is to provide the phone with 1 partition for the entire storage, rather than separate system, apps, data and media partitions. It also allows for the OS to be running while accessing the files.

MTP is much better than Mass Storage.

Thanks for the quick explanations. What I don't understand, is why the option is there under usb connections (in storage options). If the option is not available on our phone, why show it?
As far as MTP being better, it's not when you want to play music on a Mini!
I'm not convinced that MTP is my problem though, as my dad's phone (see above) will not connect either. Interestingly the option to select mass storage is not available on his HTC.

If so, what's the problem? there's no shortage of people who connect their nexus to their car stereo's (myself included)

Quick bit of clarification.
Yes it's a BMW Mini (2009)
Yes I did connect via Mass Storage on the HTC, yet it still did not work. It would not connect to an iPod Classic either. I wonder if it needs a special cable to connect? My wife's Seat Leon needed a dedicated cable to make it compatible with the car stereo.

I think what he's getting at like myself I used my Evo to USB to car CD player and could access my music files and play them and I guess that's cause the Evo has a sd card. now with the nexus i cant that IM aware of.

It's very annoying that we can't use UMS anymore. I know it's great, to have only one partition but MTP just sucks. I wasn't even able to copy files from Windows 7. The only system that has worked for me so far was Windows XP Pro.
I'd rather have a well sized Internal storage plus some Mass Storage 8/8GB or so.
And well, I'm mainly a PowerPC Mac user. Android File Transfer crashes all the time when I connect the phone (seems to use Intel-Only libraries which is very typical for Google) and on Intel Macs it's slow as hell.
So I always had to use ADB which was......very comfortable.
To the devs: Wouldn't it be possible to emulate a Mass Storage device thru software?

Keep in mind that wanting to maintain two separate partitions isn't the only reason for wanting to switch to MTP. Another reason was so we no longer had to store our data on the fragile and limited fat32 file system. In order to emulate a fat32 block device over USB you would need to be able to translate between fat32 and ext4 at a low level. I don't think there is generally a 1-1 mapping between structures in the two file systems which would make this difficult and slow if not impossible.

MTP is much better than Mass Storage.

At which point?
Some examples?
There are so many things, which dont work with MTP
I didnt found any advantages, yet

I don't like MTP either, and was missing being able to use it as a Mass Storage. My biggest annoyance with MTP is that I can't get last modified date Windows Explorer
I've not had any problems copying files to/from my Galaxy Nexus from one Windows 7 system, but another didn't work until I installed the Samsung drivers (the MTP device came up with a "?"). What was the problem you had?

LOL, because I first thought you meant a Mac Mini, but then realized you meant a car and thus a Mini Cooper... because no one I know calls it a BMW, even though it is.

Why can't we just take the ext file system? Who cares what the Mass Storage is formatted for?

I'm not sure if that would work, but assuming it does, we then have to face the issue of the single partition storage that the Nexus has. If we were to mount it via UMS, the whole phone would become completely inoperable.
