Problem is, that particular flasher which accepts command-line options to enable rd-mode, usb-host and other goodies, only seems to exist for Linux and OSX.
My understanding is that the current Windows flasher is only for updating the tablet with a new binary, or am I wrong ?
As I don't have a Linux PC handy, I would have to boot a live CD like Knoppix just to run the flasher, bit of a pain that :-)
