Enabling USB Host Mode On Motorola Xoom


Senior member Roebeet from Slatedroid has managed the 8GB  thumb drive and directly access files from the Motorola Xoom. In able to make this Xoom USB Host Mode work, you need to flash usb disk, replaced the boot.img

Before you proceed make sure that your device (Motorola Xoom) is rooted and unlocked already. If not yet you may visit http://www.koushikdu...oom-rooted.html for the details on how to do it. And in order for you to connect a USB thumb drive with Motorola Xoom you need an OTG Cable this is the exact cable that Roebeet used and proven working with the device

Guides/Instructions

Just like rooting the device Extract the img file from the ZIP above, and place it in the same folder as your adb and fastboot binaries. Then, execute this:

adb reboot bootloader

(reboots into the bootloader)

fastboot flash boot rootboot.usbdisk.img

(which loads the new boot.img onto the system)

fastboot reboot

(Reboots the device)

Finally using adb or root explorer, you have to change your /etc/vold.fstab by adding this line to it:

dev_mount usbdisk /mnt/usbdisk auto /devices/platform/tegra-ehci


This will communicate VOLD where to mount the device, when it's plugged in. After the change, you need to reboot.

The modified boot.img adds a folder called /usbdisk, so that way if you connect a USB thumb drive using the  OTG Cable, this will automount the thumb drive and you gain access files. Roebeet tested this with an HP 125W FAT32 8GB thumb drive, and it worked with no issue.

Roebeet observe that the YMMV on thumb drives is a bit alarming as it might require more power than the Xoom can supply.
