iex(1)> {:ok, usb} = LibUSB.Nif.open(0x1915, 0x7777)
{:ok, #Reference<0.2476641389.3169189905.136487>}
iex(2)>
```
### bulk_transfer read/write

{:ok, #Reference<0.2476641389.3169189905.136487>}
iex(2)> LibUSB.Nif.bulk_transfer(usb, 1, <<0x00>>, 1000)
{:ok, 1}
iex(3)> LibUSB.Nif.bulk_transfer(usb, 0x81, 64, 1000)
{:ok,
<<0, 5, 0, 0, 0, 0, 0, 0, 177, 134, 126, 152, 243, 127, 0, 0, 47, 4, 0, 0, 0,
