Will the show be effective if the LEDs flicker at a rate of 12 MHz (USB full speed) or even 1.5 MHz (USB low speed)? > >If you do this, you will find the computer does send data to your circuit. > >However the USB drivers expect every attached device to provide responses > >to requests, which your circuit will not do.

The code in linux/drivers/usb/core _is_ a driver. So when you hack it, you are operating on a driver. :-) (By the way, not much of the code in linux/drivers/usb/core is Torvalds's any more. I mean, it wasn't written by him. And it isn't HCI code either; the HCI drivers are now in linux/drivers/usb/host.)
