Looks to me like the reader is one of those that doesn't support full
260-byte commands.
I'm putting together a build that is less hard-coded as to what the
maximum data length is (it's going to be in a 'define'). I don't know
how I would access the actual maximum APDU length allowed...
I had a look on the CCID readers I have and they can be divided in
mainly two parts. Those supporting a max of 253 bytes (max CCID frame
of 263 bytes) and those supporting a max of 261 bytes (max CCID frame
of 271 bytes). You can check for yourself by searching
dwMaxCCIDMessageLength in the readers descriptions available at [1].
Here is the lists I have:
261 bytes (full length):
<SNIP>
253 bytes (somewhat limited):
<SNIP>
ActivCardV2
SCR3310
SCR3311
SCR331-DI-NTTCom
SCR331-DI-NTTCom
SCR331-DI
SCR331
SCR3320
SCR333
SCR3340
SCR335
SCR355
SDI010
<SNIP>
So if you have to select a reader you may use this criteria. The SCM
SCR 3310 you have Iain is not is the best list.
Regarding the SCM readers it is a bug in the CCID descriptor. The
readers in fact support the full length. I added a patch in the CCID
driver in revision 2498 [2] to avoid the bug.
SCM is now providing new firmwares with the bug corrected. The list of
bogus readers should be quite small now.
