The ATR of the Aladdin eToken Pro is analysed like this using ATR_analysis [1]:
ATR: 3B F2 18 00 02 C1 0A 31 FE 58 C8 09 75
+ TS = 3B --> Direct Convention
+ T0 = F2, Y(1): 1111, K: 2 (historical bytes)
TA(1) = 18 --> Fi=372, Di=12, 31 cycles/ETU (115200 bits/s at 3.57 MHz)
TB(1) = 00 --> VPP is not electrically connected
TC(1) = 02 --> Extra guard time: 2
TD(1) = C1 --> Y(i+1) = 1100, Protocol T = 1
-----
TC(2) = 0A --> Work waiting time: 960 x 10 x (Fi/F)
TD(2) = 31 --> Y(i+1) = 0011, Protocol T = 1
-----
TA(3) = FE --> IFSC: 254
TB(3) = 58 --> Block Waiting Integer: 5 - Character Waiting Integer: 8
+ Historical bytes: C8 09
Category indicator byte: C8 (proprietary format)
+ TCK = 75 (correct checksum)
Possibly identified card (using /home/lroussea/.smartcard_list.txt):
3B F2 18 00 02 C1 0A 31 FE 58 C8 09 75
Siemens CardOS V4.2B
The T=1 protocol is declared in TD1 and TD2. I guess that confuses
pcsc-lite on Leopard. A similar bug as been reported in [2]. I added
you case.

It is a software bug in Leopard.

It is also a software bug in Leopard.
I suggest you report these two bugs to Apple [3] and you add your
Problem ID to [2].
That's all you can do AFAIK.
