Same problem here... maybe a ROM problem?

------------- Edited: -------------
It seems that you need external power to the USB...
With the ROM - kernel i have my USB or my mouse does not power up.

Has anyone try with a OTG-Y cable? (i have a simple OTG with no external power)

Or try with a HDD with external power... this should also work... (i may try tomorrow with one)

You also need to mount the USB:
- with an app, download StickMount or USB OTG Helper or any other such app...
- or i think we can edit the "system/etc/vold.fstab" file. Use a text editor to open the file, add the following code to the end of vold.fstab:
Code:
# usb otg disk
dev_mount usbotg /mnt/usbotg auto /devices/platform/mt_usb /devices/platform/musbfsh_hdrc
Then restart the phone.

I am on A850_S121_28.11.2013_MULTI_LNG_by_linerty.
If anyone has a different ROM, try with a OTG cable and OTG-Y cable... waiting for answers...
