We've just released v2010 firmware for the DirectIN boxes and keyboards. It appears that this firmware is compatible with all modern operating systems (specifically XP, Windows 7, Mac OX 10.6, etc).
This firmware includes a 'field update' utility, which allows us to email new firmware for the keyboards and boxes, if ever required. The update takes place over the existing USB interface, no screwdrivers required.
Contact us for details.
