USB: EHCI Debug Port Device Gadget
This is a patch that implements an USB EHCI Debug Device using the Gadget API. This patch applies to a 2.6.35-rc3 kernel. The gadget needs a compliant usb controller that forwards the USB_DEVICE_DEBUG_MODE feature to its gadget. The gadget provides two configuration modes, one that only printk() the received data, and one that exposes a serial device to userland (/dev/ttyGSxxx). The gadget has been tested on an IGEPv2 board running a 2.6.35-rc1 kernel. The debug port was fed on the host side by a 2.6.34 kernel.
