Fix for USB Mass Storage...

I've recently installed Android to NAND and was looking for a way to mount the sdcard as a usb mass storage device in windows from within Android. I came across an interesting widget on the Android market called "Dual Mount SD Widget":
http://www.androlib.com/android.application.com-protocol-usb-jBAw.aspx
So I downloaded and installed it to see if it really works... well, IT DOES!
I used voguimg-320x480-17-02-10.nbh and Plemens Android Feb 8th build.
Here's what I did.
1. Download widget. Install. Add to Android desktop.
2. Tap on it. It will say "SD Split"
3. Plug in USB cord to the phone.
4. Notification area says "USB Connected". Don't do anything (ie. Mount it).... Instead, wait about 30secs to a minute.
5. Vista pops up the default actions window for the sdcard. My Computer also lists the sdcard as a removable drive.
I've transferred files back and forth with no problem. Not only that, Astro can see the SD card contents as well at the same time.
Now, the interesting part is that the description for the widget says:
"This widget Modifies a setting that will allow you to mount your SD card to your phone and PC/Radio/ect at the same time."
I'm wondering what setting was modified and if it is possible to build this in so that we don't need to use the widget anymore.

GREAT find! I am testing right now...
EDIT: Works excellent! It doesn't seem to be in the market for me...maybe because qvga, but I found it online.
I'm running:
Windows 7 Home Premium 64-bit
ADB Drivers installed by PDANet (not that it affects the SD mount)
Sourceforge 2-14-10 NBH (240x320)
Myn's Warm Donut with Hero theme.
This is awesome!
EDIT2: I can also run ADB/tether with PDANet and use mass storage simultaneously.

This is Fantastic!! It works. Great find man. didnt find it on the market but i did find it on the net. im using version 1.6
EDIT: you should take off the "possible" from your title as it is a perfect fix

Working perfect with Myn's Warm Donut + Windows 7 64 bit. Thanks for the tip!

Definitely works! (Using Ubuntu Karmic)
I was only able to find version 1.0 on the net - couldn't find it on the market.

How do you get it on the phone? Then how do you install it? All I have is a .apk file...what do I do with it? Vista does not recognize my phone, and I do not have a card reader. Thanks.

$1 in market. works great.

Sweeeeeeeeeeeeeeettttt Luv it luv it and luv it some more...

Man do us a favor and pl take off "Possible" from the title. This is THE fix.

Could you remind me why it's not possible without this app? is it a kernel or user space issue?
A long time ago, dzo told us that this could be solved when nand boot would be ready. Now, that's ready, what avoid solving this problem?

How fast is USB Mass Storage with the Vogue? Does anyone remember the transfer speeds it's rated for?
I'm using a class 6 MicroSD so I guess the card reader method will still be faster for me?

as I recall the notion was that running from nand would allow us the option of dismounting the sd card from the system so it could be used by USB mass storage. currently, nand still uses a cache on the sd card, so this is not yet possible.
this program allows both the system and the usb mass storage to access the sd card at the same time. I'm sure if someone cared enough to backwards engineer this we could incorporate something similar. however, why bother when there is a perfectly usable program already.

So this won't work using ext2 or fat for haret users I assume?

I'm running haret on a partitioned card (fat 32 and ext2) and it works great for me - just tested it.

~500kb write and ~800kb read (with class 4) results may vary

I confirm this also, running fat32 and 2 512Mb ext2 partitions. this is very handy. I found the 1.65 version doing a Google search, and that is what I have tested.

I would love to find out what this widget is doing so we can add the functionality to the base roms. I haven't had a close look at this yet but does anybody know exactly what it's doing?

So correct me if I'm wrong, but it would seem that if your SD card is class 4, this will still be grossly slower than simply taking the card out and using a card reader, no? 800 kb vs 4 mb / sec? or do I have the figures wrong... For small files this is convenient but for large amounts of music files etc it probably is less practical - granted not eveyone has a card reader

Right - unless you're running off SD card and can't take your SD card out . . .

apps/ widgets dissaper after connecting data cable to computer

I have the N1 rooted with cyonagen latest Rom and I notice that anytime I hook up my data cable to computer to transfer files that after I disconnect I am losing some widgets on my home screen. I had the app batt widget and Tajm and also silent widget (all installed from the market). after I disconnect all apps disappeared and left with the message,"problem loading widget". I checked in the add to home screen widgets and the names of the apps are not there. I then checked in the settings/ applications/...and then apps show as being installed on the phone.I also notice that my input method for Texting also is gone and reset to the default android Text Input. I then have to go to my settings/keyboard and then check the Sywpe box or the Swiftkey box. Has anyone experienced anything like this? its driving me crazy as I have to uninstall and intall apps all over again. Thanks in advance

sounds like you have apps installed to the memory card. its a well known issue that any apps on the sd card become not viewable when connected to usb. and wigets cannot be installed to the sd card for this same reason.

Thanks for the response, Yes I do have my apps installed to the memory card. I was not aware of these problems of widgets & apps. I guess I will have to move my widgets to memory.

Thanks to MTP, Cannot see all files on SD from PC

EDIT: Re-editing my post to remove the rant.
Basically, MTP ignores folders with .nomedia files in them... very short sighted.
Just wondering if there are any good alternatives out there, and what people prefer, other than just rebooting to recovery to mount USB?

I use wireless transfer apps like Samba. You can set it up on your network and browse the touchpad just like another directory.

True, that does work. I have been using Android Commander, which freezes sometimes... and doesn't like to connect over USB, so I have to use WiFi.
I guess what I'm hoping for is something that will work over USB which is a little faster for transfers than WiFi, which can be pretty slow for larger files.

The reason MTP ignores other files is because it stands for Media Transfer Protocol.

Yeah, I think I'm smart enough to figure that out.
Don't care. It is insufficient, because it makes it very difficult to manage the SD Card as a filesystem, forcing use of 3rd party utilities. I've heard all of Google's excuses for ending support of USB Mass Storage mode, but in the end, they did not give us a workable alternative.
The reason I use a .nomedia file is because I'd rather not have thousands of images from manga/comics, etc, show up in my Gallery app.

Well i don't know how smart you are and was just trying to be helpful ,its not often I get told for trying . I will try to be more careful/refrain before offering any advice in the future.

I use FTP to transfer files from PC to my touchpad vise versa first install ES file explorer from Play Store, go to settings> remote settings> turn on remote manage> set the parameters
Use filezilla on your PC to enter the IP add of your touchpad>quick connect and you can access your tablet files

I use Android Sync Manager over WiFi (Free in the Play Store and a free download for the PC) which lets me transfer back & forth over a WiFi network connection.

OK I will try again there is an app called USB Mass Storage Watcher. I have just installed it and put a tick in Mount mass storage automatically. Now when I connect to my PC although the tablet says connected as media device when I open the USB SD card on my computer I am able to see all files and tested by transferring a 1.3 g backup file to my desktop.
Maybe this helps ?

Phone file structure is not updating! or correct (via USB). Losing files!

A weird one here regarding file structure. Can you help? Have a pressed a crazy setting somewhere?
This has caused me to lose photos so quite important! I'd hate other to have this issue to without realizing!
If i take a photo on my phone. it goes to the SD Card/DCIM/100ANDRO folder.
If i go to ALBUM app and view that file and move it to another location (i.e SD Card/Backup) the file moves..
If i look at the photo again and look at its 'details' the folder location is showing the new location
If I use 'File Commander' app, it shows it has moved too to the new location.
All good!
If i then go to my laptop, and plug my USB into my phone (or view my phone files via the Wireless Media Transfer) and view my phone files. the photo has NOT moved location.
BUT, if i physically remove my mico SD card from my phone, place it into my card reader attached to my laptop, the SD card shows that the file HAS moved.
It seems the usb cable connectivity is not showing the updated file location.
How can this be?
Also. If i view the photo and move it via 'File Commander' app, according to my phone the file gets moved. But when i view my files via USB cable, the the file has been copied (not moved)to the new location, so now there is a duplicate.
And also, now according to the 'Album' app, the file has moved to it's new location but there is a corrupt image file in the old location.
Because I file manage via my phone and then manually connect via USB and back up files and file manage there too, because the file locations are different, I have managed to lose photos.
It seems i shouldn't use a USB cable to view my phone, but i should eject my micro SD and view it away from the phone! But Why?
Can anyone shed a light on this annoying problem/bug?
Thanks

Are you using a 'debloated' rom? Are you stopping the media server from running in any way, via amplify or greenify for example?
Make sure you have the correct drivers
A lot of Devs remove USB services from a build as it's big and takes up a lot of resources. If it's 5.1.1. build then you might be able to use Wajk's flashable missing services .

Hi there,
The phone is a month old, and only has apps from Google play on it. No custom ROM either.
I have developer options, but that's all..
I'll try the driver thing you mentioned soon to see if that helps.

Are you using a USB hub from the PC? Try plugging in the phone directly.
If you have developer options available, have you enabled USB debug?

No hub here, its a cable direct from the phone to the laptop. I've even tried different cables (not that that should make a difference).
and I the issue persists with developer on or off and with usb debugging on or off too.
Hey, could you do a favour? can you confirm that if your phone is plugged in via USB and you have windows explorer open on a folder with a photo in. (and you can see that file)
and then via your phone and ALBUM app you move that photo to a different location, that it moves it via your windows explorer too?
Thanks

I don't have USB working properly on my phone either, it doesn't show the contents of folders on the phone SD card, just empty folders, although I can copy/paste an item into a folder and it shows.
But I have a debloated rom and the USB funtions haven't been installed.
I doubt that windows will see any folder changes until you tell it to refresh (F5)

Auto install app from SD card

Hello,
I would like to know how I can make an app on my sd card...for example...es file manager...to automatically install itself onto a android tablet once inserted into the tablets sd card slot. I think scripting may be involved but I'm not sure. I have done nothing.
Thanks

Titanium backup should be able to run a Tasker app command..
haven't tried it though

Tasker
Thanks for your reply.
I'm wondering if is possible for an app to auto install without piggy backing on another app.

Not quite. The Titanium backup will be necessary on the other device as well in order for an application to auto-run itself.
I am more interested in learning how to make apps I download to a chip auto install itself once I insert that chip into another device. Something like what a CD does when you put it into a computer.
Is this even possible?

I bought this very cheap off-brand Android OS tablet off FB sales and it is limited to its pre-installed games. I can't do anything in the settings menu except view/uninstall the pre-installed apps and set the clock. This tablet doesn't have any USB ports, but it does have a micro SD card reader, headphone jack, and DC charging port. The card reader reads and plays (through the factory installed media player app) mp3 files and mp4 files on any micro SD card I place in it. I tried placing a micro SD card with other file formats (apk/pdf/epub) on it but nothing happens besides a notification saying, "SD card mounted." I am looking for a method that will have any APK ( specifically a file explorer app) on a micro SD card I insert auto-install or at least have the "install" dialog box pop up in order to expand the capabilities of this crappy tablet. Thank you for any and all assistance.

Okay, thanks for the explanation. I can tell you now, without any doubt whatsoever, that you cannot do what you're asking. You hit the nail on the head when you called it a "crappy tablet".
Without USB you're left with no options other than to install what it already allows you to install. Honestly, I'd say ditch it and get another cheap tablet, but make sure it just has regular Android on it and is not locked down.

Crap
Thanks for the information. I love saving a buck or two. I was really hoping to put movies, music, and apps on there for my daughter. I thought for sure I could get file manager on there some way.
Thanks again
