It's never been a problem. 3.x and higher use MTP so they can stop using FAT32 for internal storage. Linux does MTP just fine. What are you talking about?

why was this method needed? Xoom will not show up as a drive, unless you do this. Where as with the Droid X, once plugged in, it showed up as a drive. I hope this makes sense.

USB Mass Storage is the old method and it shows up as a drive. The Droid X is older than the Xoom therefore it is using USB Mass Storage.
MTP is Media Transfer Protocol and is the method used by 3.0 and higher.

Hmmm, from Android Honeycomb 3.1 Details ...
...Android 3.1 still isn’t intended, at the operating system level, for managing external storage devices. This detail, which came out in conversations I had with Google engineers today, explains why the Android file system organization is, well, a mess...
“We don’t want to expose the user to file locations,” explained Hiroshi Lockheimer, director of engineering at Google. “How do you manage that as a user? The not-good answer is with the file browser.” Lockheimer says that many of the experiences I’ve seen so far are what individual hardware manufacturers have enabled, as opposed to what Google has provided natively. The good thing is that Lockheimer says Google is looking at ways to do this; but the problem hasn’t been solved yet...

He did answer you. The xoom uses mtp which will not show up as a drive in Linux unlike older android which used mass storage. Mtp allows you to add files with out having to unmount the file system on the xoom. There are many threads on how to set mtp up. If you're new to Linux it may seem hard to do but its simple. Do a Google search for mounting xoom Ubuntu and you should find them easy.

totally agree. there are lots of things i understand why they're waiting, but this? come on. i could clear all on my phone.
I just want to clear up a misconception about MTP. It is not a cross platform solution for transferring files.
My post from another thread on the subject:
I can mount my Xoom in linux using libmtp and mtpfs, however, it's slow, kludgy, and generally feels like it will flake out at any moment. Additionally, even when it's mounted, I can't seem to copy music across properly; it doesn't keep the folder structure. In fact, the directories are created and any non audio files are copied across fine, but every mp3/audio file is flatly dropped into the Music directory.
I tried to copy some music onto it from my fiancee's windows xp laptop and it worked ok (though the album art didn't appear).
The move away from mass storage to MTP is a massive disappointment for me. Mass storage has always been a big selling point for me when purchasing a device and for Google to switch to using a Windows specific protocol and consider it cross platform is a big letdown. MTP on mac requires a special app and on linux, support is dire, certainly for anything more complex than simply pulling images from a camera.

I can just about get files onto the xoom, but I can't load music onto it; all of my mp3s just land up in the top level of the Music directory, regardless of how I attempt to transfer the files. I think transferring a zip file of the music and unzipping from within a file manager on the xoom might do the trick, but this isn't a good, workable solution. I understand the reasoning behind MTP, but it most certainly isn't cross platform and shouldn't be mentioned as a working solution by Google.
Hopefully people will soon realise not to keep insisting that the xoom has linux support when using MTP.

Change all the extension names in the song file name to .mp and it will allow the transfer
Then use something of your liking, I use astro file manager, and just add the 3 on the a tail end of the extension.

You're right, it's a cross-platform solution for transferring MEDIA, being the Media Transfer Protocol.
It's smart enough to detect the media files that it supports and put them in the right place. I prefer it over the old way, I hated having to unmount the sdcard every single time.
A poorly made Linux MTP library doesn't make it not cross-platform. It's an open standard for transferring media to USB devices.
It's not perfect, but it's great for a device like the Xoom where unmounting the internal memory is not desirable.
Honestly users get really confused by all of the extra directories when mounting an android sd-card anyways.

If you are still wondering:
- What is the breakdown of that 32GB Xoom internal memory (how many parition, how much space for apps / files)?
- Why Google is using MTP instead of USB file transfer on Honeycomb?
Here is straight answer from Google developer:
MTP is a big improvement over USB mass storage — for devices with lots of internal memory, a manufacturer no longer needs to come up with some hard partition between the USB mass storage and internal storage. Instead, they are all in one partition, with MTP providing access to the directory of media files that would normally be available through USB mass storage.This means there is no longer a need for apps on SD card for such devices, because what used to be the “internal SD card” is in the same partition as where applications are stored. The storage on your device can be used for either applications or media, depending on what you want to put on it. You aren’t stuck with how much space the manufacturer decided to leave for the two areas.
Oh also this means that the media storage doesn’t need to be unmounted from Android when it is being access through the PC.

Finally, true APP2SD You now have 32GB to put all your apps!!!
Sounds like a good thing!
This is a great explanation. Thanks for posting.
There is no doubt that mtp has advantages over mass storage. On the other hand I miss the ability to attach it to any computer and access files. It is not a huge problem but does add a limitation that was not there before.
That saod it is nice being able to access files on my computer without losing access to the partition on the device.

I'm sure future versions of CWM will be set to ignore that one folder.. I hope. Otherwise nandroid backups will take forever.
I'm not sure in terms of security it is a huge improvement; unless there is an option to turn it on/off somewhere.
Previously I would have to plug an Android device in to my computer, turn the device on, enter my unlock code, and then specifically allow the computer access via the USB. This morning I just plugged my xoom in and, poof, access to all my stuff.
At least before someone had to take my sdcard out at put it in their computer manually
Does MTP have anything to do with file size limit? I've seen posted on this forum that you can't load video files larger than 4gb onto the Xoom because of FAT32, is that still the case?
This MTP also seems to hide a lot of file from being seen by a pc. I open folders with File manager on the Xoom and see more folders namely the android folder which has game save data and other odd ball files. When hooked to a pc its blank. With MTP it seems all your allowed to do is transfer music, video and pics.

Still haven't got around to testing (so many things to try out!), but in some of the video threads, I've been told XOOM uses EXT4 format not FAT32, and thus, should not have that 4GB limit. I've been re-encoding video files to meet XOOM's current playback limitations, and have been reducing them to sub 4GB anyway, so I haven't tested that for myself.
So, apparently, it is still not supported and Google has no solution yet.

Google says they don't want to give you a file browser / file explorer / file manager.
Fine - there's plenty of third party apps to that on the market - but why not fix the SD card slot support?
Although I agree that some of the structure stuff is a bit of a mess - there's lots of random folders created on the SD card, like .android_secure, .bookmark_thumb etc. that you probably don't want end users seeing.
At least now it's clear that it's Google who has to fix the SD Card issue and not Motorola.

I honestly didn't read that at all...?
I read that google were working on some sort of file manager, not SD card? am I misreading it? as far as I can see file manager, and SD card are separate issues?
also the transformer, and custom kernels have the sd card slot working, so not sure who is at fault for the xoom
Why is there a difference between the tablet and the phones?
I have access to the SD Card and file system there.
Not like every Windows user on the planet has never seen "My Computer". Organizing files is not some obscure concept that is to high level for users.
From what I can understand:
USB file system means the OS access the usb disk in block level which the app (file browser) will have access to the full path of the file.
The one that is supported by Honeycomb right now is MTP. This is totally different compared to USB. The actual file system is implemented by the device, not by the computer's operating system.
http://en.wikipedia.org/wiki/Media_Transfer_Protocol
My prediction, this USB thing will be solved by the upcoming ICE CREAM SANDWICH.
Because by then, phone and tablet are merged ... everything which is supported by phone (like SD card) must be supported by tablet.
So, yeah, we must wait till end of this year or early next year (worse case).
Still, it is too long for Motorola with their "promise", no?
@Kcarpenter
Very true - but I think the problem may lie with the Xoom using the MTP instead?
or is that a load of rubbish?
Eitherway, I guess from the Google point of view - they want it simple and try and hide the stuff they don't want n00bs messing with (a bit like Apple hide everything too so all their iOS are n00b proof!)
Also Phones open up to mass storage straight to the card - you don't get access to the internal memory at all. Whereas with the Xoom you would want access to that because there's loads of space there

Who needs google when you have bigrushdog?
Just did the 3.1 update and SD card slot still doesn't work. I thought it would've fixed this.
Yea, I read that article yesterday. It has NOTHING to do with the sdcard support.
Google was explaining why android in general has a fairly chaotic/unintuitive filesystem structure... NOT why they haven't biuld in support for SD.
it was well known this update was not addressing the sd slot. No wjere not one single ppace has google or moto saidnthe sd lotbwil not be active by the deadline they stated. They could give us slot access right now but the issue is as has been aluded to they would either have to give full file sys access or no file access like the phones. For those that will say it doesn't matter give us access. It matters to them as they will be creating huge issues with tech support by the much larger majority of users that would delete things that would kill or hamper the device. I mean even on here you have tons of people that can't follow clear simple directons to flash an update without screwing it up some how. Can you imagine Suzzy home maker or joe the guy who can not figure out how to do a windows update would do with full access. My guess is they will be doing a update with a file manager and permision set so nothing past the sdcard parent folder can be accessed and programs installed will have premissions set to prevent accidental delete without going into the file manger settings to change them to allow change of permisions.
This will solve both the issues and allow both sd card and internal storage access without opening up the core files to tinkering by BDUs

It's due to the way that Ice Cream Sandwich handles the Memory. It's always live in the system. The only way to access the Memory is through MTP. There is an advantage of using such because it means that if your phone is formatted ext4 (speed increases if I am not mistaken) you can take advantage of that and still access the data. Both Windows and Linux support MTP, unfortunately Apple has not implemented such even though devices are starting to use MTP more these days.
For Further reading go here http://en.wikipedia.org/wiki/Media_Transfer_Protocol
From reading the site, there is a 3rd party implementation, not sure how up to date it is, but you might be able to make it work.
http://www.wentnet.com/projects/xnjb/ check that out to see if you can enable MTP on your mac which would reduce the need for Android File Transfer.
Also it has been a while since I have used Mac but you might be able to use these instructions to install a Ubuntu supported MTP software on your mac through X11 (allows you to run linux software on your mac) http://www.humans-enabled.com/2011/12/how-to-fix-samsung-galaxy-nexus-mtp.html

Ah. I misunderstood. Never mind, then.
closest thing would be to use something like SAMBA Fileshare

This would allow you to connect to the phone via a network share. its \\YOURPHONE .... or \\YOURPHONEIP
MTP is a pain in the ass imo. However, if you use the latest version of Ubuntu or its derivatives it should detect automatically and let you copy and paste files normally similar the mass storage behavior. Samba is an alternative, but tend to be slow.

Either a ROM doesn't have it or if it does the dev hides it some place and requires digging through 100's of stupid pointless posts to maybe if you are lucky, find the answer.

MTP is absolutely terrible, completely half baked and totally unreliable.
Right now I just discovered that ChromeOS doesn't even support MTP... Google's OWN PRODUCT...
I'd like to know the answer as well.
I understand the frustrations but the problem with mass storage is that it surrenders all control of the internal storage to a PC not a problem when that's a different chip but on the n7 and most new smartphones its an emulated partition and giving over total control would mean that android cannot function at the same time. This was brought in to stop manufacturers using two separate chips giving you loads of "storage space" but very little application space. Its a work in progress and has many issues but its here to stay I don't think any ROMs will support USBMS as it not possible on a single chip without shutting down android.

LOL. In camera mode you have access to the "Pictures" folder and is readable by Windows and other OSes. All that needs to be done is duplicate the same process and direct it to a folder called "Storage" with full permissions for the folders contents. This essentially simulates USBMS. You can even redirect mounts to that folder so that apps see it as a storage area as well so things like map data and so on are put in the "Storage" folder.
I don't have the time to mess with this but it can be done and something almost exactly like this has been done before on almost every OS.

I imagine it can be done but it wouldn't be mass storage and would require apps to be compatible it may have been done on other systems but how much space should this storage folder be allocated because it would no longer be avalible to install apps. In camera mode android still retains control of the folder other os can read that folder but files must be copied off the device to be edited. It would be good if android could mount the SD card as mass storage.
Sent from my C5303 using xda app-developers app
No it would not technically be mass storage, thus the "simulated" comment. As far as other OSes, it's already been done to a point on android already via the simulated partition that's already in use. This has also bee done using third party apps to mount folders as virtual drives.
App compatibility, if the folder is used as mount point then it is transparent to the OS and the apps. This has been done for some time now using third party apps.
The folder size could have the same limitations that the storage area has already been limited to. If coded so that it is part of the boot process then everything outside of system apps would only see the virtual area. Kind of like what's being done right now.
Dual mount. This has been used with much success and allows for PC and Android access to the same storage area at the same time.
