1. The usbip_status file is no longer created for interface 0, but for
the whole device (such as
/sys/devices/pci0000:00/0000:00:01.2/usb1/1-1/usbip_status).
2. Per interface information, such as interface class or protocol, is
no longer sent/received. Only device specific information is
transmitted.
3. Since the driver was moved one level below in the USB architecture,
there is no need to bind/unbind each interface, just the device as a
whole.

Will fix in V2.
