I am a newbie to USB. I want to provide a middleware between application and device USB device drivers no windows. It will be a composite device - CDC ACM, ECM and mass storage.
Can somene please provide pointers for me to start? Are there are any user mode client drivers (like hid.dll) whose APIs I can directly call from the applications?
Also are these windows provided drivers thread-safe?
Your help will be much appreciated

Milind,
SiLabs USB MCUs only have enough endpoints for a two device composite device. If you are not using a SiLabs part, why are you asking here?

As for "middleware", I can only think of a port snooping device that relays things on. Problem with "no windows" in that senario, is that then you must be using Linux or a Mac, because you HAVE to use Windows if you are using Windows (identity).
