I now have written some C# code to update login and password , and the Flash code via the USB. thats rite, no ISP interface required. Achieved by using the LibUSBDOTNET library and the filter drivers. also experimented with some SMD components to make stuff smaller.

all programming is done by EP0 directed to the 'Device' using controlled transfers. have moved all USB encoding into the C#. All the login/PW codes are now in Flash ram because EE is just too damn slow. this also allows me to expand the amount of login and Passwords i can store.
