Hey all. Currently I am trying to get a simple USB keyboard project working. I've taken this project: m and modified it to use only one button, attached to PD3. When the button is up, the report buffer sent to the computer should be 0. When the button is pressed, it should send an 'A'. The hardware ...

Well I finally got it working. Rebuilt my circuit and used the HID-Mouse example that comes with V-USB, and it worked for some reason. Now my problem is when I try to turn the example from a mouse to a keyboard, it shows up under keyboard devices in Windows, but tells me 'this device cannot start'. ...
