As mentioned in the Microchip forum thread, I will suggest you to switch your device to use either HID or vendor specific device. For HID, there is a cross platform HIDAPI which you can use. For vendor specific device, you can use libusb-1.0/libusbx which is a cross-platform library. Under Windows, libusbx supports either Microsoft's WinUSB driver or open-source driver like libusb-win32 device driver or libusbK device driver. -- Xiaofan -- 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
