I use this USB host cable and it works great. Have tested it with my 750gb Oyen and 320gb WD Passport external HDD's, several usb flash drives (8-16gb), San disk USB memory card reader, and a USB keyboard.

For those having issues getting their Xoom to recognize USB storage devices here's what I've got and did to get it to work: I flashed my XOOM (3.1) to the 2.6.36.4 Tiamat_Xoom-v1.4.4-Full_Throttle Kernel and was unable to get the USBMount to recognize drives or storage at first. I installed USB Mass Storage Watcher from the market (it's free) and it works awesome! Can mount any storage I want (NTFS, FAT16/32, HFS, HFS+, EXT2, ETX3, EXT4) with any capacity. I think this app will work with any rooted Xoom (or other devices). Under my Kernel my USB host is located under/usbOTG.

Hope this helps.

Thanks for your post, im having trouble getting my Wifi Xoom usb host to work, i have tried making a cable from the tutorials around here and i have also bought an OTG cable but didn't get any luck having it working, im on HC 3.2 Tiamat 2.1.0 Tachi stock GPU , i tried installing busybox - OTG watcher - Drive Mount etc. and followed all kind of guides in the forum and on google with no luck, i tried usb mice , more than 6 flash drives, usb 3g dongles and other devices without any indication of any kind of connection or powering up, so most probably the problem would be from the cable...as i ordered xoom usb otg cables from ebay and until i receive them i was wondering if there might be anything i was missing?

Sounds like your cable is not OTG. A lot of them are not. Try it again with your Moto cable when it comes. Also, try rebooting with the cable and drive plugged in, with OTG Watcher running. That has worked for me in the past.

Xoom 3G, stock FW 3.2, non rooted and ot cable

So - just installed USB Mass Storage Watcher OTG - https://market.android.com/details?i...tcherotg&hl=pl

Pendrive is recognized by the program immediately and displays the mount point /dev/block/sda - but unfortunately the next value is 0MB. And this is like that on every pendrive. Do I need root to mount it, or do you have any other idea to mount my pendrive without root?

You do need root to mount the drive-to use Xoom in USB Host Mode.

Only root? Is that all that needs to be done?
You need a kernel or rom that supports OTG. Tiamat Odachi kernel, Moray rom, the 4G rom, and the Rogue Rana kernel should all support usb host mode. You will also need a real otg cable and probably an app that helps you mount the drive, such as USB Mount All or Drive Mount.

it works great on rooted stock kernel 3.2 with "Drive Mount" but from the market you can not install "Drive Mount" it says not supported.

Just tried with a genuine motorola OTG cable, which works with the same stick because I used it for upgrading my UK one to US ICS 4.0.3, and it doesn't work without rooting. I still can't root mine yet because my micro SD card for backup hasn't come!

read usb drive from rooted xoom

i have rooted my xoom (wifi usa)based on http://forum.xda-developers.com/showthread.php?t=1446469

I installed stickmount app (https://market.android.com/details?id=eu.chainfire.stickmount&hl=en) from market.

i used Micro USB Male to USB A Female Adapter (http://www.amazon.com/Micro-USB-Mal...YMU6/ref=sr_1_2?ie=UTF8&qid=1329151612&sr=8-2)

once connected to xoom the usb drive ,StickMount app recognize and mount it on specific drive (folder) which display on screen for some duration.
then goto "ES file explorer" or "Astro file explorer" and select that folder and you can see the contents of usb drive.

usb drive should be in format Fat32 mode.I have not tried with NTFS or other format.
Hope this helps somebody.

You got it to work using that USB adapter? That's not a USB OTG adapter. It really shouldnt work using that one.

Reboot loop after trying to get external USB to work

My Xoom WiFi running Team EOS build 102 would not see my USB drives. I installed 'USB Mass Storage Watcher' from the market. This app then prompted me to install the OTG version. I followed instruction and removed original version before install the OTG version. The OTG version also prompted me to down load another version of Busy Box, which I did.
I could then see one of my USB (see size and space used), but could not see files or folders in the mount location. I restarted my Xoom (I live in a windows world and reboot fixes a lot of issues LOL), Xoom got stuck in reboot loop. I went into recovery mode and clear my Dalvik, but this had no effect on reboot loop.
Luck for me I had a Nandroid backup from 2 days earlier (pheew). Restored this and back to normal.
Not sure if anyone has had this problem, but I strongly recommended making nandroid backup before doing any device driver updates.
