macOS - open fails for bluetooth device

[kypalmer]

Hi!

Originally issued this in the cython-hidapi group, and they directed me this way.

Operating System: macOS

Behavior:

• running python3 under sudo (REPL)
• hid.enumerate succeeds -- shows all bluetooth and usb connected HID devices.
• device.open succeeds in opening a USB keyboard (reads work)
• device.open & device.open_path fail with a bluetooth keyboard. 'OSError: open failed'

Expected Behavior: a connection to be opened to any HID device in hid.enumerate()

reproduction:

>>> import hid
>>> hid.enumerate() // several HID devices listed
>>> h = hid.device()
>>> h.open(1452, 544) // apple USB keyboard -- works
>>> h.close()
>>> h.open(1452, 569) // apple bluetooth keyboard -- OSError: open failed

I assumed from Apple's bluetooth docs that bluetooth HID access would work the same as USB.

Any thoughts? It's my first attempt at using the library, so I may be doing something wrong.

Cheers
