I'm also having issues with the hardware keyboard.
My device is the o2 Serra branded version of the Touch Pro (RAPH120) that uses the standard Touch Pro keyboard layout (Numbers across top with Fn+numbers for symbols).
The problem I am having is that the Shift & Fn keys are not working. So when I press Shift+S, I don't get a capital and just stays in lower case, and for Fn+1 the input gets ignored instead of inserting the ! symbol.
I've tried the Fuze-TouchPro keyboard cabs but those don't fix anything.
I'm now trying the fixes suggested by L4RRY by changing the 07FF key from "HKEY_LOCAL_MACHINE\SOFTWARE\Tegic\eT9\IME\Keyboar d LayouFiles\" but so far have not found a fully working one, it seems that they will all work to get the Shift key working but not the Fn key, however the Fn+DEL does work.
I will report back if I manage to get anything working.
Everything else looks great so I can't wait for the final release and the Kitchen release so I can build a WM6.5+Sense2.5.2012 Stock-like ROM.
Thanks for all the work Yozgatg!
Testing using "eT9.Raphael.wwe.kmap.txt", "eT9.Rhodium.wwe.atnt.kmap.txt" and many others seem to be producing random responses to the Fn key.
At the minute I am using "eT9.Raphael.wwe.kmap.txt" and the Fn+number key combinations work as and when they want. If I hold the Fn key down and repeatingly press 1, I will eventually get a ! symbol, but this happens as and when it wants and not after any certian amount of presses.
I have also noticed that the CAPS and FN lights above the keys will flicker and flash when trying to use those keys instead of illuminating until they should automatically go out (E.g, After using a Fn key combination)
Before this ROM my phone has not had any issues and as it doesn't seem like I'm the only one I'm guessing my phone has not just developed a CAPs & Fn key fault.
Let me know if you want me to test anything imparticular.
All the best,
HTC Touch Pro (o2 Serra)
ROM: Energy Standard Reference with Sense 2.5 (WM6.5 21911)
