Many chip vendors have high-speed USB devices for mass storage. There are ready build but most of them are freely programmable through an integrated microcontroller, such as the TUSB6250 or connectable to an external microcontroller such as the ISP1582/3. Most of the vendors have development boards with ATA and or SD-slots and supply source code examples for mass storage. You just need to change it in the way that it offers a CD device instead of a harddisk and add an interface to change the logical media stored on a bigger flash card. Or you just swap the flash card itself. Micro-SD are very small and cheap to get 1G sized. -- B.Walter http://www.bwct.de http://www.fizon.de bernd@bwct.de info@bwct.de support@fizon.de
