[Q] Browsing Tab from a PC using USB slave - Acer Iconia A500

Hi,
Why isn't the Iconia seen as a USB mass storage ? My computer (Win7) sees it at a "device storage" and don't assign any drive letter to it :-(
Moreover it doesn't refresh the content. I created new files on the A500 and if I connect it to my PC I can't see new created files or new installed application's directories, why ? (I hit F5 with no result)
Thanks,
Seb

install the ACER USB Driver from the website ACER that should resolve your problem

Thanks but , done, of course, before connecting the tab for the first time ;-)
USB debuging works fine, I can connect with adb.
Can you see the tab as USB mass storage with a drive letter assigned ?
Thanks,
Seb

Is this a normal behaviour ? No drive letter assigned to the A500 when connected to a PC with USB ?

Well yes, is normal since you dont need to un-mount internal_SD while connected to the computer.
And if you write some file on A500 while connected, you can see that file instantly on the iconia.

The A500 used MPT not Mass Storage, so it won't appear as a mounted drive with drive letters etc. It should show up under My Computer like some music players do (Cowonn for example can use either mass storage or MPT)

Thanks.
I hope this will be a choice when connecting in 3.1 ;-)

I don't think this is something that's going to be changed. I had originally thought this might have been an issue specific to the Iconia, but it looks like it's cooked into Honeycomb.
This forum post has some details, although no link to a specific post by the "Google developer" who supposedly explained why MTP not USB Mass Storage.
The basic is that MTP allows Honeycomb to not have to have a separate partition to be mounted, and that it allows the tablet to share access with the PC (as opposed to dismounting the SD card mount to allow it to be accessed by the USB host.)

Except this makes it impossible to sync with apps like HandBase which require a drive letter be assigned. Works perfect on my Atrix but not on the Acer Tablet.

It must be a Honeycomb thing - My Archos 101 (A2.2) doesn't need the extra mSD unmounted for me to see TWO drives in my PC, with peoper icons and eberything (2 = internal mSD "drive" and plugged-in mSD).

[Q] problem with USB Debug

I have a problem with USB Debug mode. When I select debug mode and plug the Tab into my computer, I only get the usb connected notification. The Tab's drives don't show up in windows explorer. But when I look in device manager, both drives are showing. The drives also show in the Disk Management utility in windows as H & I but no media.
Has anyone come across this one before or able to offer suggestions on how to sort it.
All other USB modes work ok eg. Mass storage, Kies and Media.
Nobody got any ideas? I really need to get this working so I can use Super one click to root my Tab

accessing android phone (USB Mass Storage)

am i being stupid ??
im sat here with my HTC Desire (running GingerVillain) connected via USB to my transformer dock. Ive enabled USB mass storage on my phone.
Can i find it using File Manager ? No ... nor ES file explorer ..... am i going mad ? im sure when i was at home i was able to find a USB drive through file explorer ... is this a quirk of Android mass storage or am i just being thick ??
It doesn't work for me either. Would be nice if they got this to work soon. I thought maybe it was because I din't have 3.1 but even after the update it won't work. Kinda sucks.
this is similar as connect together two windows pc, It never worked like that . why should work here then?

hmmmm. but isnt the whole point of the Android USB Mass storage 'mode' that it works like a USB Flash drive ? ... and the Transformer copes with USB Flash Drives !!!
im not suggesting that its like plugging two windows pcs together ????
i had a thread about this last week.
it does the same thing for me (i have an HTC desire). very annoying!!!!
the only way i found to easily transfer files was using a bluetooth transfer app called:
"Bluetooth file transfer" free in the android market.
its not that fast (bluetooth limitation) but allows transfer of smaller files etc.
i wanted to transfer all my music (like 4gb) but over BT that would take days lol
so i have to wait to copy paste it all to a computer, copy paste to a USB stick, copy paste onto the transformer
OR, upload on my wifi to Dropbox and then download onto my transformer. uploading 4gb would also take days....
hopefully it will come soon...!!!
connected my san francisco (CM7) to the TF, it's mounted as 'removable' correctly...
I have my external HITACHI HDD on NTFS working fine but when I've tried to connect my Nexus S in as a drive its just blink on Transformer task bar and thats all
I would love to see my NS connected to Transformer so I can do more work on it.
Any1 know how to make it work ?
I have the same problem. I am on 3.1, but my X10 mini is not seen by the Transformer. No problems with thumb drives - or even a Microsoft wireless mouse (with own dongle) works perfectly.
It's a little surprising that an Android device is the only thing that is giving me problems!

[Q] SD card like mass storage

Hello,
I would like to ask to you if anybody know how to connect Point Of View Mobii 10.1 Tablet (it is same like Advent Vega) to PC with SD card like mass storage.
USB driver is installed.
OS is Win7 64bit.
Official ROM 1.10.
USB debugging is enabled.
But when I connect tablet to PC I can not see any notification about connection (in tablet or in PC nothing).
Thx a lot.
I have found it easier to give up juggling with USB to transfer data and now use Android Manager over WiFi. If this is an option for you, have a look here - http://global.mobileaction.com/download/android.jsp
It looks good
It looks good, I will test it ...
But basically I would like to use my tablet like standard mass storage. For example at home, office or somewhere alse with USB cable.
Thanks for your hint.

[Q] USB file transfer elocity a7

is there a patch that lets me use the usb port for data transfer or am i just missing it?
I have used a usb stick(16GB) and transfered files from it. But it seemed to choke on large files like movies.
I dont think it can handle USB HDDs, but I never tried.
I dont think the USB port works as a "device", works as a host. I read somewhere as well that you can somehow "change" the port with some magiv reboot/button holding combo.. but i read that on the internet so it might not be true.
1. USB Port at our A7's can work as "device".
Look into my manual: http://forum.xda-developers.com/showpost.php?p=11742434&postcount=2
Section 2. ADB (Android Debug Bridge)
2. Large files are restricted by VFAT. No more than 4GB.

[Q] Any way to get USB Mass Storage instead of MTP?

Not entirely sure what kind of process might be needed, but is it at all possible to use the older method of transferring files between a computer to an Android device (USB Mass Storage) instead of MTP?
MTP (in my experience) is... not ideal in most cases. File transfers are seemingly slower, can only do one thing at a time (I think if your transferring a file, you can't even browse other folders on the MTP device), and sometimes file transfers just get stuck for no reason. Was trying to copy over a few PDF's to my N10 and it seems to just hang randomly, had to reboot the device 4 times already (twice to just create and rename a folder).
what about the option in settings -> storage -> and tap the menu button on the top right and select USB Computer connection?

I had the same problem at first, but I realized my USB ports on the front end of my PC arent USB 2.0, so I plugged it into the back, and works like a charm. Just a thought.

I already did that and tried both options (MTP & PTP), but the N10 does not show up on my computer at all in either case, with or without USB debugging. I have had no such problems with my other android devices (all still running gingerbread, in case that matters).
My N10 is rooted and my computer runs xubuntu 12.04; I don't have a window box to test... Any suggestions? Thanks!

Unfortunately the answer is no.
There was a long discussion on the Galaxy Nexus forums about it a while back.
I also wish for a usb mass storage option for compatibility with radios for playing music. They don't read mtp/ptp for any generic one I've come across.

Hmm, but what's the main thing stopping this from being possible? I thought I heard of a few JB devices that were able to get USB Mass Storage (LG Optimus G I think has a method, or whatever the phone is that has similar parts to a Nexus 4), and a Galaxy Tab I used to have had Mass Storage in ICS.
Mass storage is possible when the sdcard volume is actually a separate disk. On the Nexus 10 this is an "emulated" sdcard and cannot use USB mass storage safely because that protocol gives exclusive control to PC.
The easiest solution is to use one of the many wireless transfer apps like AirDroid.
Another option for Linux users if you really want a wired transfer is to use adbfs. This is a FUSE wrapper around the usb android debug protocol.
https://github.com/spion/adbfs-rootless
adbfs would give you seamless mounting just like USB Mass Storage.
Another solution, though not a seamless mount, is QtADB: http://qtadb.wordpress.com/
This is another wrapper around the usb android debug protocol.
Oh my god, thank you for the AirDroid recommendation. Holy crap is this program useful with my new nexus 4.

dear espionage,
i just wanted to share this with you in case it would be helpful. in fact, you might even have more technical know-how to find out how i accidentally managed this useful fix. first, the reason i was looking for this MTP to USB storage was my habit of synchronizing my thumb-drive to my desktop using any free synching software. this of course, can be only be done when the storage device is recognized as a DRIVE. unfortunately, i believe with the updating of the OS to 4.1 onwards, the USB storage option has been removed, and now only access to MTP is possible. the bad side to this is that one's device is recognized as a portable media device and this means i can no longer synch like i did before the contents of the SD card to my desktop.
second, i found the solution accidentally by installing MultiMount-SD v.2.5 into my Sony Xperia V (LT25i). accidentally i say, because when i clicked on it for the first time, it wouldn't work. it showed a help tip saying that i should trying enabling what it called an MTP fix provided by the program. i did this, restarted the program and guess what happened. there occurred a looping sequence (i guess unending) device recognition-mount and unmount (the PC sounded this off many times), since there was no end to it, i decided to UNINSTALL the program even while the recognition loop was going on. in the meantime one could see a drive appearing in the EXPLORER with a (?), then it would appear with an assigned drive letter, then finally disappear, and so on.
i successfully uninstalled the MultiMount apk, and surprisingly even with the message that the device wasn't properly recognized or installed, i could now connect my Xperia and it mounts as a USB storage device and no longer MTP. to test this 'accident', i tried connecting it to my desktop, running Windows 7, and it worked without any hitches! I don't really mind losing the MTP option, sides it's very limited in its connectivity with the PC. Another bonus, is despite this, i can still communicate with my device through the MyPhoneExplorer program that allows one to send text messages and other stuff. This was one wonderful accident.
oh, one last thing, even with rebooting my phone, the setup seems to have become a 'permanent fix'. now, when the device is connected one sees in the activated portions in the top menu saying: USB Storage - SD card connected to PC. This was never there before... And i wonder what MultiMountSD must have left permanently to allow my Xperia V to now connect as USB storage. Yahoo!!!
i hope though, you could see what the technical side of this accident is, so that somehow something more stable could be done or programmed without having to go through the 'accidental' procedure i have detailed above.
ciao,

I had this issue with Ubuntu 12.04 too, after I updated to 13.04 it started to work like a charm . You can also try changing the rules in your PC, you can find how to do it in the Google website .

Thanks SmokinCharger! I guess it's quite clear that attempts to allow certain devices to be read in USB Storage mode is a hardware configuration. If your device isn't designed for it, then it won't be able to do this. It's like wanting your volkswagen to have a 6th gear... thus, what was posted previously is true:

*I also would like to apologize what i've posted earlier regarding my accidental discovery with Multi-Mount SD. What the app actually did was to access a feature in my device (rooted Xperia V LT125i) which i wasn't aware of. All the time, my device was actually configured to have both MTP and USB Storage.:silly:
So for such devices that are hardware configured only to be MTP or PTP, the only 'solution' or 'alternative' would be to "ROOT" them and set them up with OTG (On the Go) USB access. This may have some hitches, but i've been using this quite a lot. Sometimes though, a RESET is required so that explorer applications would function normally.
Thanks again. I guess this will be all for now in our attempts to reconfigure something that is hardware defined in certain devices.

You're welcome. Chainfire is a great and well known developer that has development many great apps including Stickmount. Look it up in Play especially the Pro version, which is "The price is aimed at being approximately one beer at the bar ". It works with mounting the UBS OTG. The Pro will automatically mount and unmount.
