I cannot use the Wacom tablet on OSX because it fails to be configured in Chuck. The problem seems to be happening while opening the HID interface with this line in "util_hid.cpp":

result = (*interface)->open( interface, 0 );

it returns the negative result(-536870203). This is what Chuck reports:

mouse 'PTZ-431W' ready

[chuck]:(5:INFORM): hid: starting PTZ-431W

[chuck]:(5:INFORM): | hid: configuring PTZ-431W

[chuck]:(3:SEVERE): | hid: error configuring PTZ-431W

I'm not an expert in device drivers, perhaps someone can figure out why it happens.
