I believe that you must be rooted to use the Xoom in USB host mode. I've been rooted from a couple of days after I bought my Xoom, so I don't remember.
You do have external sd card (read only) right?

Make sure that 'USB Debugging' is disabled.

i'm afraid you need custom rom for this.

Then as I thought, you need to be rooted and install a custom kernel or rom (Tachi kernel or Hammerhead rom for HC3.2) that says it enables usb OTG host mode in the releas notes. Then you can use your OTG cable (and the free app USB Mass Storage Watcher OTG) to mount and use thumb drives and newer HHDs (that don't require much power to run).

Thanks for the reply. Where can I get the steps for rooting? Is it possible to go back to custom rom after rooting?

Yes you can flash a custom rom.
For the correct rooting guide for your Xoom model (3G or WiFi-only, country of origin) check out the Xoom Heaven thread in General section 1st, to see if your Xoom model is addressed there.

[Q] USBOTG doesn't work

Hi to all!
Here's the problem that I have.
After upgrading my Xoom (US 3G) to Tiamat 2.1 Hammerhead USBOTG stopped to work. When I try to connect flashdrive via this cable it blinks only once and that's all. The folder USBOtg is empty -> nothing is shown (but I know that there are files). I tried to format flashdrive to various filesystems (NTFS, FAT32) -> no result.
Another strange thing after upgrade is with MicroSD folder. It shows me only old data. All new one that I copied to it via PC it doesn't show at all. AND!!! PC doesn't see the content of folder with name "external" on Xoom but when I copy there files from PC then Xoom can see them.
May anyone advice any steps to return usbotg and microsd in normal working state?
I tried to re-flash Xoom with previous various versions of firmwares (mods) -> the same situation.
BR, akadimka

Two different issues--if you read the release notes with the Hammerhead Rom, Team Tiamat removed the USB Mass Storage enabling that had been in earlier Rom, due to various difficulties. So that means you can no longer use your PC to copy files into the micro sd card in the Xoom, but you can cop files directly to the sdcard using an adapter or card reader. Your Xoom should still have access to the files on your micro sd card at mnt/external1.
The usbOTG works fine for me but it needs the help of an app like USB Mass Storage Watcher OTG or Drive Mount. Both will work. It also helps to reboot with the drive plugged in the first time if you are having a hard time getting the Xoom to recognize it.

Thanx! Drive Mount helped me with recognizing and mounting flash drive (but only after Xoom reboot with drive plugged in). USB Storage Watcher OTG crashes everytime when I start it with drive connected -> with disconnected it starts normally but won't see any after-connected drives. Ssems that I'll use Drive Mount program
As for MicroSD -> even connected directly to PC and copied some files to it Xoom still sees only old data. Any ideas?

Actually, try checking the folder mnt/external1 (1) as this is HC3.2's official mount point. The Microsd mount point is an artifact of an older Rom.

i am using hammerhead rom with tachi kernel.
yup the usb otg not working.
tried both usb watcher and drive mount.

Make sure that you are using a REAL usbOTG cable.

A real USB otg cable? What needs to be special about the cable in order for it to work?

This is where I will suggest that you do some research. Start with this forum and then search elsewhere. Just today I have answered this question 3 times. Search on my name and you will see my posts with your answer.

Your cable will never work because it is not OTG. OTG has a different pin configuration to allow the Xoom to function in usb host mode. If you are handy with a soldering iron you could make one, but why not buy one, they are availble. Here is my Google search for USBOTG Xoom to get you started: http://www.google.com/search?hl=en&source=hp&q=usb+otg+xoom&aq=2s&aqi=g1g-s9&aql=&oq=usbOTG

[Q] Is possible run apps with data on USB using OTG???

I want build my own OTG hidden and attached to a case, but I don't known how can move the data aplication to an usb and run the games or apps? Exist something like link2sd or app2sd for USB???

How you are going to charge the device when all the time there is an OTG device attached ?

Y USB cable?

??? give me a hint. To charge it, You will need to unmount the ext drive (disconnect usb device) and plug in the usb charging cable.

format it and try to make sure it works with another device to confirm its working then double check you have all the right stuff enabled in yout moto g.
eg usb debugging, root status, busybox perhaps., ect.

I have tried with 2 pen drives. Both working perfectly on pc..
My phone is not rooted. What is usb debugging??

Don't need root, busy box or usb debugging set.
What file system format are the drives? You need FAT32 for best compatibility between devices.

I have formatted the pen drive in fat32.. When I connect any pen drive in moto g, it is showing ' Damaged USB storage'
And in the notification area 'USB storage is damaged. Try formatting it'
When I try to format from moto g, screen goes black for 2 second and nothing happens..
Really fed up... I have not rooted my phone.. It is running kit kat

Please help me

[Q] USB OTG mount problem

HI guys, I am very satisfied with this phone when I got it a week ago. However, I was facing sometimes my phone unable to mount USB OTG storage, I mean the USB drive won't lit at all / detect by phone, I have to reboot the phone then it only gets detected. Any other way round to solve this without rebooting?

I haven't had trouble using my OTG usb stick so far. Have you tried using Nexus Media Importer? It lets you mount/unmount on demand.

Does it show the USB drive as unmounted in the Storage menu?
Also, did you try a different thumb drive with a different filesystem on it? I cannot reproduce your issue at all.

Ok after my investigation, the USB OTG still works but just the USB port of my phone unable to supply power, if I use a power bank + USB hub then connect to my phone, my phone detects the USB drive. Similar to somewhat my phone requires external power to mount. But if I reboot my phone then the USB OTG work properly again though. Until I remove and remount it next time, then the problem occur again.
Currently my phone setup as my signature. No custom kernel but just recovery.

Ok I know whats the problem now. You can try during deep sleep insert in your USB OTG. It can't detect at all even if you remove and reinsert. Have to reboot the phone. So my guess is right I think. The phone have to screen on to insert USB OTG or else it cannot detect.

I don't have 1TB but I have 500GB and it works without external power.

few older phones supported 500gig portable hard drive too but did not support 1tb, my phone will be delivered tomorrow I'll update here then.
Fingers crossed.

I just tried a 16GB USB drive through an OTG cable, and it didn't detect it. My screen was on, and I was running stickmount as well.
I had to restart the phone to get it to detect.
I have the same issue with my N8010. Have to restart to get it to recognise the USB.
Hopefully, there will be a simple solution to this.

Well it seems in my case it's rather random, sometimes USB drives (or HDD's) will mount, other times nothing happens at all, while some drives refuse to mount at all.
Maybe it's faulty cable don't know?

I have problem
I was able to mount USB 3.0 64 gb without any formating, and it shows in settings too, but now I can't see it in settings and in El file explorer it is very slow.. What should I do, I can't format to fat32

Same Problem
I can not get any drive to stay mounted, cable works fine on nexus 5 so do the drives but no luck with opo has anyone any info on this since oct 2014 post

I can not get any drive to work too. I tried variuos, from 1gb to 500gb, also tried with FAT and NTFS, none of them working. Please help. I am using CM12S, newest firmware, it doesnot work, on 11S it did not worked, i tried on Oxygen OS, doesnot work too.
