Hi all:

We have a product that has MC9S12B128.

Inorder for the customer upgading the firmware in the field, we are going to put USB controller on the processor board.

When our customer recieved the updated .S19 file,they can copy the file on an USB flash drive and then plug it into USB socket on the unit.

Our unit should recognize it automatically(like the PC does) and then start downloading(This is the part that I don't know how).

Is this project doable?

Please help
