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

USB stick compatability?

Can u plug a full size USB stick into the xoom at all?

u need the host cable- by the Motorola one it will work, alot of the cheap ones won't.

that one works, i have several. The same guy sells an led-less version for $4 that works too.

how does it work? Does it show up as a new folder in the file manager?

You will probably need an app like USB MassStorage Watcher or Drive Mount (both free) to mount/unmount the drive. It will show up on the same directory level as sdcard (internal storage) and external1. It will be at usbOTG.

Thanks for the tip! I got the Drive Mount app and it did the trick. Was starting to worry that the cable I got on eBay was a fake.

Cool! Thx 4 all the posts...

i m in same boat. I have XOOM wifi USA version. It is NOT ROOTED.
does it work to read USB drive without rooting?
current OS version on my XOOM is 3.2.1 (HTK75D)

No, you must be rooted and running a custom kernel or Rom that support usb host mode.

Thanks for reply. I m totally new to rooting etc.
well is android 4.0 is going to release for this XOOM model soon? and does it resolve this issue?

I'm betting that our developers are making us an ICS Rom with usb host mode support...

will this also work with a usb gender like http://www.amazon.com/USB-Gender-Changer-Female/dp/B000BSN4UY/ref=pd_sim_e_2 in stead of a usb otg?

I have installed android 4.0 on my motorola xoom wifi usa version.
it is NOT ROOTED.
Can i read usb drive ( pen drive or external hard disk ) with this Or still rooting is needed?
I have following adapter.
http://www.amazon.com/Micro-USB-Mal...3?s=electronics&ie=UTF8&qid=1327371621&sr=1-3

is only rooted is Ok or it need to install other custom OS version?
it will be great somebody can reply ASAP.

So there is no other app that doesn't require root? I just want to hold on rooting the device..is USB OTG supported with 4.0?

Wifi Only MZ604 USB OTG

I got a USB OTG cable but when i plug it in nothing happens. it looks all confusing, I am running build 17 of Team EOS ICS. What do i do?

Try downloading/running one of the apps that mount external USB drives.

I have tried about 3 of them but nothing happens.
Is there a certain format it needs to be ? (Fat32) etc.
Do i need a special kernel?

Which cable did you buy? I'm about to buy an OTG cable as well.

[Q] Mi 4i USB OTG Not Working

Hi,
I am extremely sorry if this is not the right place to ask this.
I got my Mi4i on the first flash. As soon as I got the phone, I did the MIUI 6.5.3.0 (LXIMICD) update. I did not check the USB OTG before the update, so not sure if it worked before the update or not. When I tried USB OTG, the Mount USB storage option is greyed out - always. I tried 2 different USBs and 2 different cables - still no luck. I am starting to suspect if its something wrong with this ROM release, as lots of areas in the setting is greyed out for me (for example, in the Headphones and Audio effects settings, the equalizer settings are always greyed out). So, have any of you tried USB OTG on MIUI 6.5.3.0? Any insights?

Yes I can assure u that USB OTG is working fine on MIUI 6.5.3.0
Check if the USB is a fat32 or ntfs?
Ntfs file system doesn't work with mi4i
Format the pen drive in fat32 and try again
I also tired a sd card reader it works brilliantly
Audio settings will be greyed out until u plugin headphones. Try any earphones or headphones then check if it still is greyed out

Thank you for the reply but I am still facing the issue...
Yes, the file system is Fat32 and the mi4i is still not recognizing the USB. Since the USB OTG is working fine for you, I suspect my OTG cable might be damaged ( weird- I tried 2 different cables).. Maybe I should try a different OTG pen drive?
PS: You were right about the audio settings, those worked when I plugged in the headphone..

same problem here.keyboard and mouse working but no usb drive with same otg cable. Otg card reader also not working.

If you're USB or SD Card is of huge capacity it may take time to load so I would suggest you to wait for a while, Android checks if the storage has an errors. It doesnt show in MIUI though. But wait for a while after plugging in.

I have sandisk otg 64gb and it works without an issue. Make sure it is formatted with FAT. Other FS like exFAT and NTFS wont work, not sure about Fat32 though.
Hope this helps.

I bought a new 16gb Sandisk 3.0 OTG usb and its working fine for me now.

What's working:
* FAT formatted USB flash drives
* USB Mouse
* USB Keyboard
What's not working:
* NTFS formatted USB flash drives
* Portable USB hard drive
* USB Gamepad
I have an OTG cable lying around. Will soon test Linux file systems (ext2, ext3, etc.). Give me more suggestions, and i'll test it on the Mi 4i.

Aren't there root apps which enable ntfs support by installing a ntfs-3g driver?

The functionality is kernel-baked and not all kernels support the ntfs-3g driver. Also Xiaomi seems reluctant to release its sources anytime soon. There are alternatives like Stickmount however.
