SIMtrace hardware questions

Good evening. I am interested in your SIMtrace hardware board and i would like to ask a few questions if possible. ( http://bb.osmocom.org/trac/wiki/SIMtrace) First of all i am interested in sniffing data between both SIM and USIM. As a result, i would like to ask if your product fully works with these cards and if i will be able to capture all the data between the mobile terminal and the (U)SIM. (eg. usim authentication) Furthermore, i have some queries about the wireshark integration. The wireshark intefration supports the GSMTAP protocol. this protocol is used in order to parse the data between the SIM card and the mobile terminal. Does this protocol also supports parsing data between the USIM and the mobile terminal? Thanks Stefanos
