Hi Steven,
Can you talk this over with Christoph and send me a patch when you agreed?
He's the one that made the Apple-SWAP key patch. Meanwhile I suggest the
following patch:
==== //depot/projects/usb/src/sys/dev/usb/input/ukbd.c#47 -
src/sys/dev/usb/input/ukbd.c ====
@@ -896,8 +896,7 @@
hid_input, 0, &sc->sc_loc_apple_fn, &flags,
&temp_id)) {
if (flags & HIO_VARIABLE)
- sc->sc_flags |= UKBD_FLAG_APPLE_FN |
- UKBD_FLAG_APPLE_SWAP;
+ sc->sc_flags |= UKBD_FLAG_APPLE_FN;
DPRINTFN(1, "Found Apple FN-key\n");
apple_keys = 1;
sc->sc_kbd_id = temp_id;
The hardware that Christoph was using had an Eject-key, while yours didn't. I
think the patch above will make both cases work.
Christoph, do you have any comments?
