There should be two things involved in Software: - (1) UDC-specific logic to kick in the hardware test mode mechanisms, based on control requests made using libusb Some generic user mode driver that makes such requests, using libusb, to any UDC (or HCD) that has test mode support. The driver would work best in conjunction with a hardware test harness that probably includes an oscilloscope and similar tools to examine the signals generated, verifying integrity etc. - Dave - Dave -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
