Specific USB Key development

[Philippe DA SILVA]

Hi all

I've never been coding on the hardware side and so, I am willing to find some help around to help me getting the following functionalities working

My current project involves, if possible, that a person can uses a specific USB key to store encryped data so he can take it with him and by plugging the USB key, getting access to it. For security and no other use reasons (users may want to store other data on it), I want the USB key not to be recognised as an USB drive by the system but when plugged having an application catching the plugged event from the system and getting its content to be decrypted and displayed

Knowing that, I'd llike to know if it is doable. It sounds like I should develop my own USB driver and maybe also have some hardware specific production to avoid oher USB keys to act the same way. If you have any idea on how I could do that, I would appreciate

Here is a summary of the requested features
- USB Key never recognized as an USB drive by the system
- Automatic catch of the plugged event from the system
- Read and Write features on it

Thank

Philippe

You would have better luck posting to comp.arch.embedded.
