Yes, but it's really a triviality to plug in a USB cable to that 4 pin connector on the bottom of the PCB. Doesn't filco also have a connector like that for it's cable?
I would say it depends on the plate support design whether or not it will work, since all other differences aren't too hard to overcome.
Swede, it's a little unclear as to how the case connects to the keyboard? Are you sandwiching the plate, or using screws and standoffs, 'cause if it's the former, or something like it, me way already have limited CMstrom compatability.
