I've tried tried two different usb drives with two different OTG adapters all of which work fine in other devices, but when plugged into the tablet do nothing. I was expecting the drive to be automatically mounted. The option in settings to mount external USB storage is also greyed out.
Not a satisfactory one. A few USB drives don't seem to work, most do. There are no obvious differences in partition layout, file systems etc. All tested drives work just fine on my galaxy s3.
