The host could provide a public encryption key to the card reader. Of
course:

  * With a tampered USB cable, there still would be attacks possible,
    though different ones. That is, unless the reader can know the
    identify of the host, which would again require a priori exchange,
    so nothing gained.

  * This is very likely not part of the existing API (PC/SC?).
