Question: Is there a Linux driver available for the ISD-300 / ISD-200?
Answer: The ISD-300 / ISD-200 is mass-storage class compliant it should work with the default Linux mass storage driver. Information about using ISD-200 in Linux is avaliable in an external site in the link http://bjorn.haxx.se/isd200/ (This is not officially tested by Cypress)
