I have updated the Ergodex DX1 driver that I support to include Windows 8 support (tested on x64, untested on x32). In order to do this, I had to purchase a VeriSign Authenticode account and sign the driver. The setup experience should be a little smoother across the board now that the driver is signed. This did require a capital investment of $100, and that will be a yearly fee, so if you get use out of this product I would appreciate a contribution (Available at our website at http://www.in-character.com and linked from in the tool using the "$" link on the main screen).
The driver, version 3.1, is available on our product page at http://www.in-character.com/Pages/ErgodexDX1Suite.aspx.
