I have implemented a dual CDC-ACM USBX device, and would like to incorporate a mechanism to programmatically differentiate the two ACM's at the Host. One mechanism would be to have each ACM carry with it it's own Serial Number, but I am at a loss as to how to do this. The best way (I think) would be to incorporate a unique String Descriptor Table for each device. Please give me a hint as to how to do this!
