0x30 - n - transfer_buffer. If direction is USBIP_DIR_OUT then n equals transfer_buffer_length; otherwise n equals 0. For ISO transfers the padding between each ISO packets is not transmitted.

0x30 - n - transfer_buffer. If direction is USBIP_DIR_IN then n equals actual_length; otherwise n equals 0. For ISO transfers the padding between each ISO packets is not transmitted.
