Getting closer...
First, I should mention that with your patch, now the 0x65 control request
happens before the T=1 negotiation. The original ifd-eutron.c and safesign
both do it afterwards. My device doesn't seem to mind though.
However, the 0x65 0x98 causes the device to fail. I must change it to 0x65
0x01. All other control codes seem to not make a difference, so I've left
them alone. I've also noticed that I can just take out the 0x65 request and
it still works. The problem is, I don't know if changing it or taking it out
will break other cards.
The device also doesn't like your PTS request. It will accept it, but then
the device doesn't really do much from that point on.
send: ff 11 18 f6
recv: ff 11 18 f6
send: 00 00 07 00 a4 00 0c 02 3f 00 92
recv: f8
OpenSC times out. I guess it wanted more than an f8.
Attached is a patch that makes the device work. It should be applied after
the patch you gave me. From it, maybe you can decide what to do. It also
includes a fix for the extraneous 0 byte before the ATR.
Once these issues are resolved, does it mean that we're done with the openct
part, and that the rest of the issues are to be solved within opensc, under
the StarCOS driver?
