I should rephrase that: libhid (and libusb) can't claim a HID device exclusively under OS X *without the help of a kext*. So you could have cross-platform code if you can get the kext working. >> >> You shouldn't have to reboot to use a codeless kext - the most that >> might be needed is unplugging and replugging the device. >> >> That said, I haven't been successful in creating a codeless kext that >> actually lets me claim the device. > > You know, I actually gave that a stab this morning.

Maybe I'll try over the weekend :) Where did you install the kext?
