Some minor bugfixes and changes

- added licence info
- ATUsbInterfaceDescriptor: fix adding endpoints to list
- added ExampleCreateScsiBlockDevice
- changed timeout to 5000
- Usb4JavaUsbDeviceCommunication: when claiming interface added code to detachKernelDriver and then claiming device again
- fixed transferredCount in all 4 methods
- BulkInTransfer added check if returned buffer is actually empty
- UsbMassStorageLibrary: added low-level debug code
- UsbMassStorageDevice: fixed transfer type
- int sets flag so that we know if we need to close it
