[PD] HID Crashing

Here is what the Pd window gives me for the print method in hid. It
appears to detect the sidewinder (my gamepad) in all its glory, but
the buttons do not register when pressed. I tried using the test
option in the help patch to no avail as well. The gamepad should be
fine, since I was using it with hid last year, and it works with other
applications.

On my system with the below configuration, devices listed 5 and above crash Pd.

Hope that helps!
