[Q] cannot mount usb flash disk on eos 2.0 - Xoom Q&A, Help & Troubleshooting

The first time I bought the USB OTG cable and tried it to mount my flash disk, it worked flawless. But after several weeks and I tried to mount it again, it simply could not be mounted....
I am currently using EOS 2.0 custom rom.
What is the problem?

Are you talking about a usb thumb drive? Are you using any software, like Drive Mount or Stick Mount? My 32gb thumb drive auto mounts. You really have to go into settings/storage to unmount it so you can remove it safely...if you didn't do that earlier, that could be your problem now. If you are trying to mount an HDD, you will probably need one of the apps mentioned (Drive Mount works for me).

Flash the rom again thru recovery. Should work then.

[Q] 3.2 with Katana. No USB stick mounting

Upgraded to 3.2, installed Katana, no USB OTG recognition, then installed USB watcher OTG. Now it sees the drive, says it's mounted but nothing shows in Root Explorer? Any ideas?

Where did you choose to mount it? You have to choose. I chose "mount at next available mount point," and I found it at external2.
It didn't give me that option, and it wouldn't use any other point, but after I went and created a few directories within /mnt like USB1, usb2 ect now it works. Thanks for giving me the idea.

Thank you guys
This thread saved me. I upgraded to rooted 3.2 with Tiamat kernel 2.0.0
Its great but I noticed it no longer had usbOTG support. I tried everything I could think of and was a no go. I thought I was gonna have to restore my ROM manager backup of rooted 3.1 but then I came across this thread.
Learned about USB watcher OTG and works like a charm. I love that I can also mount it to my own custom folders and I can now UNMOUNT. Such a needed feature.
Thanks guys !!!

[Q] External USB drive with rooted 3.2 and Tiamat 2.0

I've a Xoom MZ604 US WIFI ONLY , with rooted android 3.2 and tiamat kernel 2.0 . I tried to use an external USB drive ( various pen and HD ) but without success.

Did you reboot while the drive is connected? And of course, are you using a tested usbOTG cable?
Had you been able to connect/use the drives on HC3.1?

I tried to reboot with stick connected , but nothing !
I received the cable yesterday ... after the update to 3.2 , so i don't know if the USB stick works with 3.1.
mmmmmh... about the "tested cable" ... mine is not a cable but an adaptor ... and i hope it works
i can't get mine to work either. Using the same things you are. I have the official motorola cable for it. Never rooted in 3.1, didn't root til 3.2, so no idea if it would have worked then. I am wondering if it is the kernel that is causing this issue. Cause i have seen others post of the same problems with this kernel... Relly wanted this to be working. Go into the hospital thursday for surgery, be in there a week. Wanted to be able to load files off thumb and portable HDs to watch movies on. Can't do either now
Working Now
I initially had the same issue with my USB drive. I then pulled the usb drive out of my "official Motorola OTG cable" then plugged it back in and it now works well. Backed up by SD card to my USB drive . . . no problem.

If you can update to the new Tiamat Manta Ray rom you will be guaranteed to have usbOTG function with the free USB Mass Storage Watcher OTG app. It's now working like a charm with the Motorola OTG "camera kit" adapter.

Yes! You need an OTG cable, such as the Motorola Camera Connection Kit. There are others available for less money, but you have to make sure it's really OTG, because it has a different pin configuration.
In addition, you may need to use one of two free apps to help mount the drive--USB Mass Storage Watcher OTG, or Drive Mount.
I've found that it may help to reboot with the drive plugged in (at least the first time).
With this set-up you can use a thumb drive or a large HDD.
My Xoom is fine but my friend bought one and he cant otg with 3.2 unless he roots, right? ... The toshiba does otg out of the box. This was his major buying point. Anyone know why xoom m doesnt yet others will? And yes, he has otg cable.

I tried both of them n failed in both
The drive mount requires busybody. But after installed it, the drive mount apps keep DC.. couldn't use at all
And for the USB mass watcher, when i launch it it asked me to download the latest version, but the latest version isn't compatible with 3.2
What should i do now =(

I'm not certain if an unrooted Xoom can really access OTG/usb host mode. People say that, but I have been rooted from the start, so I never tested it out.
But i can't even download it from market @@
I jhave it now butkeep fc . Argh
Yeah, I have been rooted since day one as well, so I was unsure of the stock 3.2...

Are you sure you have an OTG cable?
Also, what are you trying to connect? Some people have had issues with thumb drives but not with an HDD.
thumb drive.. yup i m sure its a otg

Does it dim or does it crash? If it dims and you can't do anything, try turning the Xoom (like from landscape to portrait), with auto-rotate enable, and if a dialog box opens, choose an action.
If it is crashing, can you try an HDD like a Passport?
not dim nor crash. The device just suddenly go black n have to boot up

Cm9 on a bad USB port.

Hey everyone....I've posted many times about my infuse USB port not working to sync to my computer....so my question is this...I'm running cm7 loving it...can I put the cm9 zip on my external SD card through a card reader and flash it on my phone? Is it possible and what steps do I need to do? I would love cm9 or other roms for that matter but its not life and death.
Sent from my SGH-I997 using XDA
No, it has to be on the intr sd...not the ext sd...but why can't you copy it from the ext to the inter from with in your phone?
I copy files all the time to/from my ext to inter sd....
But if you need to return to stock...
I would also put zen tool on there also to back your ROM...
Make sure you have all needed on your phone and copied over to your intr sd.....
Since yore USB is not working? Is it a hardware issue?

Yes its apparently a hardware issue and pretty common I guess on these phones.....just stopped connecting to the computer. It charges but I can't sync.

Try a different usb cable, different usb port, make sure the drivers are installed, enable usb debugging?
Did you select mass storage mode?

Hey There,
We had the same issue with many units and solved all by doing the following:
-Flashing the unit back to stock
-Performing a factory data reset after flashing(This is a must)

[DEV] Native usb storage otg

Made some progress with USB storage without the use of an app. Setup so far is really simple. Add a line to /system/etc/vold.fstab that looks like this:
dev_mount usbdrive /mnt/usbdrive auto /devices/platform/tegra-ehci.0
Still need work on getting the external storage managed by the system.
WARNING:
This is just a first step and with no way to unmount using Android's storage manager you may corrupt your external storage.

Wow I JUST got my OTG yesterday. Fantastic timing.
what this means... hopefully
As it stands now, adding this line will cause your N7 to automount a usb drive to /usbdrive. You will see "preparing usb storage" in the notification bar and your file explorer of choice will see the data in /usbdrive. Unmounting is an issue at this point. I hope to fix that in a few days when I get the time.

I believe this works on the N7 I am waiting on my cable to test. I realize you want to do it without a app but the syntax should be close.

Correct me if I'm wrong but I believe that CM10 already has USB Storage OTG built into it with the last few nightlies.

a day late and a dollar...
Haven't been following the cm10 builds. Still gonna push forward for the exercise.
People who don't run CM10, can use this method. Would be cool if unmount is done.
Guys, quick question as I'm receiving my N7 tonight, the usb stick format can be ntfs? Or only fat32? Thanks
EDIT: saw from other thread, ntfs seems ok as well. i already got the tab and will start unlock and root.

Just wanted to confirm that stickmount works well with the N7.
I have it installed and I've used it on two different usb drives.
A 32GB PNY USB2.0 Flash Drive Stick
And an 8GB uSD card inserted into an elago II USB Reader.
Both worked without any issues.
However, I'm still intrigued by a method to get usb mass storage support natively w/o an app
That does it...I give in! I gotta try the twrp recovery. Feel like I just decided to cheat on my girlfriend.

I saw a post about it somewhere around here. Referenced Amazon.uk, the title was USB otg that work and ones that don't I believe. Google can probably get it. If I wasn't using the app I would hook you up.

Can I ask, does this support NTFS r/w? or r/o.
Everything I've tried, aside from USB OTG Helper--including a CM10 kang rom that claimed to support ntfs OTG--will only mount r/o.
Including the command $ mount -t ntfs /dev/block/sda1 /usbdisk. I guess it's the ntfs driver or something? but it will only mount r/o. Even $ mount -o remount,rw /dev/block/sda1 /usbdisk does not work, it still is ro.
