Yes, they should be class compliant devices. When I mentioned drivers I was talking about the possibility of an alternate driver that would simulate the 'jiggling'. I was just throwing one possibility out there. Mainly just to illustrate the point that anything running on your PC would be subject to some scrutiny from the bank.
Ah, apologies. I misread your comment.
If you wanted to know the jiggler is safe, "just" write your own firmware and program a micro to do it.
