I've (successfully I think) ported a USB driver for the WH1080 weather station to Mac OS X by compiling the driver http://meteolinger.lowlevel.cz/anonsvn/driver/wwsr.c using the command
after installing macports of libusb and libusb-compat.
The device presents itself as a HID device and as such it is claimed by the Mac HID kernel driver when the usb cable is attached. According to http://osdir.com/ml/lib.libusb.devel.general/2007-01/msg00058.html it is possible to install a null kernel driver that prevents the HID driver to grab the device. Have followed the instructions in that post but it seems that the HID driver still grabs the device. Output from wwsr (debug enabled):
The Info.plist:
Somebody know if this Info.plist suffices and how to trouble shoot the HID grabbing? How to check that this null kernel extension is loaded?
