This series makes the Qemu usb-tablet work correctly with OS X/macOS guests without the need for a special guest driver.
* The usb-tablet should not have a boot protocol of 2. Other OSes seem to ignore this, but the IOHIDFamily driver stack chokes on it for anything but conventional (relative motion) mice. * A "mac_compat" boolean option is added to the usb-tablet, which changes its report descriptor to specify a usage of 0x02 (mouse) instead of 0x01 (pointer). This is required for correct operation in the Mac HID driver stack. Changelog ========= v1 -> v2: * v1 Thread was "[PATCH] hw/usb/dev-hid: add a Mac guest compatibility option to usb-tablet" * Always apply the boot protocol (bInterfaceProtocol) change to usb-tablet, not just when the Mac compatibility option is active. The original value of 0x02 was determined to be incorrect according to the spec anyway. * As the boot protocol change is permanent, separate interface and device descriptor constants for the Mac/non-Mac variants of the tablet are no longer required, and have been removed.
