Thank you for the info. This will allow development to get to work
and support be able to assist customers who encounter this problem.
Still, are there any hints to help me figure out why this problem
(i.e. my non-smart-card device being treated like one) is
happening? Naturally, it is preferable for this product to not
require disablement of system functionality.
Here's what's (probably) happening. You have a "vendor specific" class
USB device (class 255, I believe). Since nobody knows what a "vendor
specific" class device really does - each one's, well, vendor specific
- the smartcard system launches pcscd on the theory that maybe what
you've got is a smart card reader.
Normally, pcscd takes one look at your device, blows it a gentle
raspberry, and ignores it. Two minutes later, it quietly dies, and
everything is pretty much okay.
In your case, pcscd seems to have taken an unnatural liking to your
device and is getting all excited about it. That's not good, and we
should find out why it does that. (It may mean that it *thinks* your
device is a smart card reader that it knows about. It may also mean
that it's just really confused.)
If you want to help, take a sample of pcscd in its excited state and
send it in as a Radar report. That'll help us figure out what it's
excited about...

If you won't need smart cards at all on your system, try modifying /
private/etc/mach_init.d/securityd.plist. Change
<string>/usr/sbin/securityd</string>
to
<string>/usr/sbin/securityd -s off</string>
and reboot. This should keep securityd from trying to handle smart
cards at all.
To just make pcscd not launch on Vendor Specific devices, use
-s conservative
which will still launch on USB devices of the smart card reader class
(but ignore Vendor Specific devices). It's a bit less asocial than "-s
off", which disables smart card operation entirely. (Apple recommends
that people use smart card class readers where possible, because Mac
OS X contains a class driver for that device class.)
