German layout Apple Extended Keyboard II M3501 ^ key not working

[DOCaCola]

I have recently build the adapter and it works well so far. What i noticed is that pressing the ^ key (left from the "1" key) is not being registered by the system. Tried both on a Macbook and my Windows 7 machine.
I booted up my old Centris 650 to confirm this is not a hardware issue with the keyboard. The key is working fine there.

Using a Teensy 2.0 with latest revision of adb_usb cf1eb8f
All other keys seem to work without issues.

Check scan code for the key with hid_listen and let me know. I'll add it to keymap.

Now i took the time to try all keys. I noticed that the = key on the numeric keyboard seems to be mapped to something else. Instead it of = it outputs an ´ (the key left from backspace on the german keyboard)
This one outputs:

Thank you for the info.

I pushed patch into master branch. commit: 9a72c7b
This fix assigns 'Non-US backslash' HID code for the key on left of 1 and includes some other ISO/JIS keys support.

As for second problem, = key on keypad generated 'Keyboard =' HID code(0x2E) but 'Keypad ='(0x67) now, though this code may not work on Windows.

I have no ADB keyboard in hand now and I can't test this fix.

Looking good. The ^ key now works as expected. Thanks :)
Yes, the = key on the numeric keyboard doesn't work on Windows, but outputs correctly on the macbook. I guess this is acceptable.

[DOCaCola]

one more thing :)
First of all, i guess that the Alt and Apple Keys are switched is intended to give the Keyboard a more Windows like layout.
That aside, there seems to be an issue with the right Alt Gr key. It doesn't seem to be detected as such. I am not able to insert special characters on Windows. Example: ´Alt Gr + ß´ should output \ (backslash) on the German keyboard under Windows. "Alt Gr" seems to act as another Alt key.
This issue is specific to Windows, as OS X seems to treat both Alt keys equal in that regard.
Here the output from the right Apple key (which acts as Alt in the current adb_usb build)

ADB keyboard has no distinct keycode between right and left Command keys unlike Option and Control keys..
You should place Alt on both Option keys to get AltGr key.

On my keymap I put Alt on Command keys, as a result, both Command keys send left Alt keycode.

Thanks for the clarification. I have remapped those keys and it works now.
Thanks a lot for your help!
