Usage is now:

h = hid.Device()
with h.open(...):
    # pass

I would prefer:

with hid.open(...) as h:
    # pass

Much like opening a file.
Something like this could be more easily implemented with #109 .

Can you please add backwards compatibility for the rename, so also the old device would still work the same way? Maybe just device = Device would suffice.

@prusnak I've added exactly that.
device extends Device with a warning in the constructor.

Reverted all (potentially) breaking changes.
