drive letter - Nexus 7 Q&A, Help & Troubleshooting

Not sure where to ask this but is there anyway be it stock or rooting to get the computer to assign the nexus 7 a drive letter like it were a usb or something instead of as a portable media device??
* I haven't rooted I'm looking into it.

umm,anyone??

Android no longer supports UMS (usb mass storage) to mount the memory, it supports MTP, which as you rightfully said mounts it as a media device, this in theory has loads of benefits, but in practice can cause issues.
It is in theory also possible to reinstate UMS but it would have to be worked into a kernel and/or rom, and I am not aware of any such modification for the N7 yet, although I have not really looked.

Is there a mount USB storage function on the Tab7.7?

I would like to mount the internal and external storage via 'USB MOUNT' like what I normally use on Galaxy based phones, I tried checking the debugging mode and it still launches the MTP application, is there a way around this ?
I'd like to know this too!
AFAIK mtp is the new way to connect for honeycomb, ics onwards.
google moved away from usb mounting after 2.3

In short, no.
That's interesting because the new ICS-equipped Coby 9742 mounts as a regular, removable drive rather than a MTP device. That, and when the Samsung 10.1 and 8.9 were released without microsdhc provisions I was dumbfounded, a certain dealbreaker. Two disturbing trends:
1) MTP
2) no microSDHC/XC
My HTC Sensation running an ICS rom, also still has the standard USB mass storage mode too. It may be something a Rom developer can add as part of their Rom.

USB OTG to mount Galaxy Nexus?

I'm looking to mount my Galaxy Nexus to my Nexus 7, but when I go about it like I would a usb stick stickmount doesn't see the sd card. My USB OTG host cable works perfectly with my 64gb SanDisk Cruzer thumb drive, but it is NTFS formatted to get around the 4gb file size limit. I can read files, copy files off of it, and stream files from the stick just fine but I am unable to write to the stick. I'd like to be able to get rid of NANDROID backups, playstation games, other large files, etc without having to connect to a computer.
1. What format is the "SD card" on the Galaxy Nexus? Is it ext3/ext4 which stickmount can't read?
2. If there is a better way to make an NTFS formatted writable stick I'm all ears...
3. Maybe I should just get a smaller separate stick that's FAT32 and thus writable...
Nokia?

I haven't seen that done with Android devices just yet... maybe it's possible, but I haven't heard of it. I know that Nokia phones can hook up as external storage to the N8 (saw a video on YouTube) but that's as far as I know.
Also, to write files to an NTFS volume on Android, it seems that you need to add the "fuse.ko" to your kernel (in /system/lib/modules) I tried doing this with the Nexus 7 ToolKit, but I wasn't about to insmod it (make it run) since the fuse.ko I has was apparently for a different version of Android??? I've literally spent about 10 hours "searching" on xda and all over the internet. It seems (oddly) that everyone in the Android community is content with a measly 32GB total limit, and 4GB file size limit. *(facepalm)*
This won't work. Android, with 3.0, stopped exporting storage via SD card, because of reasons[1]. If at all, you can have a vendor modify Android as to export your plug-in SD card, but not the internal storage.
Currently, Galaxy Nexus etc. offer their files via the 'MTP' protocol when plugged in, and there's no support to act as an MTP client AFAIK (since Linux support for MTP sucks balls).
[1]: since a separate storage for /data, /system etc. was considered uncool, as it made you dependent on a predefined partition size (remember 256MB 'internal storage' phones and Android Market "uninstalled due to low disk space"?), newer phones, and especially the Nexus line, features a single storage container.
The USB mass storage interface works like plugging in a hard drive into your system: it gives you block-level access, and this is usually synonymous with "exclusive" access, as it results in destroyed or confused file systems if two independent systems try to mount the file system on a storage device.
Problem is that Android still needs to be able to actually run, so it can't give you block level access to the internal storage. The only way that would be feasible is to turn off your phone completely and have the bootloader give you USB mass storage access, which is counterproductive.
Thus the need for something like MTP (which was already around for a while) was born, which gives you the ability to make it look like a file system, but actually work on a client/server basis like FTP.
tl;dr: no usb mass storage ("usb stick mode") with galaxy nexus. ever.
Can't check at the moment, but can't you mount the SD card from CWM recovery on the Nexus in USB Mode rather than MTP?
What we need is a file manager that can use MTP. I'm also interested in hooking my Gnex up to my 7. There must be something out there that can do this.
Bluetooth file transfer.

[Q] Disable 4.1.2 usb mass storage auto mount??

ok guys i've got a minor inconvenience with my nexus 7.
first of all my device:
i'm running paranoidandroid 2.23 with clemsyn's power saving kernel. which i can recommend because it works like a charm and uses very little battery.
but now to my problem:
i'm using a 60gb external HDD with an OTG cable connected to my nexus 7. the problem now is, that the hdd is formatted in ntfs, which i won't change. everytime i connect my hdd to the nexus 7 the android system automatically mounts the partition READONLY as /storage/usbdisk.
i'm using "Paragon NTFS & HFS+" to mount ntfs partitions as R/W, which does of course not work since the partition is altready mounted by the android system. so now i always have to manually unmount the partition in android settings and then remount it with Paragon NTFS & HFS+.
my question now is: is there any way to disable the android system's automount of external usb mass storage device?
i know it's just a small inconvenience but it really gets to me, there must be some way around this hassle.
thx in advance

Sorry for not having an answer, just wanted to +1 this. I could really use this solution as well.
Seriously need an answer. I tried deleting the last line of vold.fstab, which worked, but then my music players couldn't see anything, even if the drive was mounted with Paragon or OTG Helper

[Q] Native USB OTG Storage Support

Hi,
there are many ROMs out there for our beloved Nexus 10, but it seems that only few support external storage via USB OTG. I couldn't figure out how to enable it manually. Is there any kind of mod or kernel that does the trick? I tried some apps on the play store, but I don't like the idea of an app sitting between the android system and storage hardware.
Thanks in advance!
Cheers,

I think all custom kernels have USB OTG support in them, and maybe I am ignorant since I dont care about OTG support but I thought all "major" ROMs worked with them. Hmm.
Maybe you're right, but in that case USB OTG seems not to necessarily include USB OTG storage. I noticed, that while ParanoidAndroid did not recognize my USB storage device, it was still able to detect things like mouse and keyboard correctly.
Example:
[ROM+KERNEL] [AOSP] AOSP+ 4.2.1 - JOP40D - Cust.Settngs+OTG+OC+More - 20 Dec 2012
http://forum.xda-developers.com/showthread.php?t=1998585
USB OTG Information:
1. Auto-mount to /storage/usbdisk
2. Files accessible by all applications, processes and users
3. Currently works with FAT & NTFS partitions
4. Full read-write access for FAT USB disks, read-only access for NTFS USB disks
5. This does not conform to the Android 4.2 multi-user capabilities. All users have full access to the OTG storage
6. If you are using another custom kernel, make sure it does not overwrite the ramdisk changes or you make lose OTG support
I am sure there are other ROMS. Do a "OTG Support" search in the "Nexus 10 Android Development" forum and find what suits you.
Cm 10.1 and AOKP both support native OTG for USB drives. :thumbup:

ROM? try root + StickMount + *browser for root
ops! i didn't read the last part of you post :/
thanks for your replies,
it seems like the only up-to-date ROMs that aim on native USB OTG storage are indeed cm10.1 and aokp.
however, apascual89's paranoidandroid might soon support it too.
i think that is worth having an eye on it.

[Q] USB host controller issue

No device connected to the micro USB host through OTG cable is detected. Neither mouse nor keyboard or (micro) SD Card. The kernel claims to support USB host controllers. Checked with three different OTG cables, all sold claiming to work with Nexus 7.
Everything was also checked on stock ROM and kernel (JDQ39) unrooted and rooted.
Same cables work like charm with my i9305 Galaxy S 4 LTE just as Stickmount and Nexus 7 Media Importer (mouse, keyboard, storage).
Nothing works however with my Nexus 7. I feel very frustrated and cannot resolve this issue no matter what I try.
Any ideas?
Thanks
Nexus 7 grouper, rooted, Stickmount, Busybox installed
OS: JDQ39 based Smooth rom 5.1
Kernel: M-Kernel 3.1.10
Try a different kernel... Bugs do happen so OTG might be brought ken on that kernel.
Sent from my Nexus 7 using xda premium
PS: I know bricked worked, I thought Franco's worked too. Dunno bout M-Kernel, I actually avoided that kernel because it didn't look like USB-OTG support was in it when I searched the thread.
Thanx answering
I'll try Franko. As I remember, M-kernel has OTG support. But
Shouldn't even stock kernel support keyboard and mouse over OTG?
And why does the Nexus Media Importer app not work either? That
doesn't even take root...

Depends on how you're implementing it. I know with apps like StickMount and OTG Helper, they won't automatically start media scanner on the new device unless you have the paid version.
The rom in my Sig actually has USB-OTG support for the Nexus 7 built in (would still need a kernel that supports it of course), so it automatically mounts a thumbdrive, and it shows up under Settings -> Storage , and shows as USB Storage and you can unmount it from there, acts just like an SD card would on other phones. Only downside is no exFat support (nor NTFS I think). Stickmount can do it but you have to provide the exfat binaries in /sdcard.

Stickmont free detects connected USB storage immediately and mounts it. The USB drive and the files on the device connected by
OTG can be seen by any file explorer in a normal case. Also, when connecting mouse and/or keyboard (even wireless)
via OTG/OTG&USB hub a USB icon and a USB device connected message should pop up in the notification
bar. Nexus Media Importer app should also see the connected device if formatted FAT32.
At least, that's how it works on my Galaxy S3 using the same hardware ( 3 different OTG cables,
mouse, keyboard, USB sticks, memory cards, etc.)
I have flashed four different kernels (M, Motley, Franko, Stock). There is a significant difference in
performance but unfortunately not in USB host device detection behaviour.
I do appreciate all your helping effort. Thx
