Doesn't work for me either!
I'm kind of puzzeled how this can work in the first place. I thought the S3 has no UMS because Samsung didn't want to pay the license fee.
Doesn't UMS require some kind of driver/modules on the device and are they present regardless of licensing ??
Can somebody please enlighten me?
