It would be desirable to implement the PKCS#11 interface on UART so that the HSM can be added to embedded boards lacking USB host capabilities. This addition shouldn't change the security model beyond doubling an existing interface.

HSM uses CCID protocol that runs over USB. Not sure how this UART communication whould take place, specially because I lack of this kind of hardware.
