what are you doing? it looks like you're trying to get/parse the binary descriptors when they're already fetched and parsed for you. See UsbConfiguration.getUsbConfigurationDescriptor() and UsbDevice.getUsbDeviceDescriptor() and so on. Also as far as the endpoints: UsbDevice.getActiveUsbConfiguration.getUsbInterfaces() the for each interface: UsbInterface.getUsbEndpoints() interate through and look for what you want (then getUsbPipe())
And the "port status"? Are you talking to a hub? The format of your variables and headers looks like you're working from a Windoze trace....are you trying to write a javax.usb driver based on a trace or do you actually have the protocol (specification) to your device?
