Storage class implementation

Post by Sceadwian » Sun Mar 22, 2009 3:55 pm

Is anyone working on or is there available a Storage Class Device that works with the AVR-USB code? Data transfer would be easy to implement without drivers if a file could be downloaded from the device that was dynamically generated. Or even allowing access to SD or other devices hooked up to an AVR.

The problem here is that you need to use bulk endpoints which are not allowed for low speed devices. You can still declare them, but some operating systems won't accept them.
