Also look at the USB offload stuff as one example of how the voice sound path goes through the USB controller on the SoC on the latest Samsung Galaxy phones that are shipping now :( There's also devices with the modem/network connection going over USB, along with other device types as well. Android Auto is crazy with almost everything hooked up directly with a USB connection to the host system running Linux. > I guess only developers are using USB during development to flash dev > images heh. I wish, we are reaching the point where the stability of the overall Android system depends on how well the USB controller works. We are a product of our success... thanks, greg k-h
