Doma, that's right, because the CSP is the "bridge" to the TSS (trusted software stack) that talks to the TPM. So for any management software to work with the NTRU TSS, it has to go through the CSP to do it. Since Wave's CSP is the only one that works with the NTRU TSS, Wave's CSP must be used by Infineon, since their CSP only works with the Infineon TSS.
TPM chip --> TSS --> CSP --> all other TPM software
