I have started thinking about a hobby project I'd like to do.
I want to create a board to adapt a device that reads and writes xD cards so it will be able to use USB flash drives.
The plan is to use a small uC and make one end a USB host and the other pretend to be a xD card, but I have a couple of obstacles to overcome.1/ I can't find any information on the xD electrical or data spec. 2/ I can't find any information on the current consumption of USB flash drives.
Does anyone know where I can find out this information? Reverse engineering it sounds like too much work for this project.
