I'm assuming keyboard mode works without issue, is that correct? Does Windows see Grifta 100% correctly in DInput mode in the USB controller control panel applet?
From what I understand, keyboard mode does works as expected. In dinput mode, a trigger pull would result in your view looking down (ie. pulling your right joystick down on the controller), and you could not assign any buttons to in in the Xim manager. They appeared to come up correctly in windows, but I never actually got around to testing any games with it.
I'm still waiting on a replacement dongle...
