In an unexpected but most welcome move, the driver for these was submitted to cgminer. I've reviewed their driver and suggested some changes which they've already resubmitted so the driver is now part of mainline cgminer and will be in the next release due out today.
What device do we need to interface? The usb-PIC cable?
I have no idea. I just reviewed the code and helped the code merge so I don't know what they anticipate cgminer will run on to run these devices since I don't own one.
