remove interface argument to Dev.read() call

[JonathonReinhart]

The interface argument was removed at some point and is apparently unneeded.

I also specified the timeout argument by name, so this will still work with older versions of pyusb that still have the interface parameter.

This is identical to a8480b45 in pyCCSniffer.

This mirrors the change I made at https://github.com/andrewdodd/pyCCSniffer/pull/2.

Just noting that this change was implemented at some point in the past and this could be closed.
