figured I'd bump this thread as I have a slate 7 and I'm trying to get the thing to recognize my usb disk drive. Currently I'm having no luck.
I've tried plugging the usb drive directly into the slate as well as into a powered usb hub and nothing seems to make the device see the usb drive.
The hub is good because the usb keyboard I'm using allows me to navigate the bios with the keys and what not but when I go to the boot menu, where it says usb cd drive it just says ":None" and only lists the internal hdd.
this has worked just fine with several other types of tablets but this samsung is the first to simply not recognize the drive at all. Bios settings are all factory default BTW.
