Re: Dell Smartcard Drivers

This is an OpenPGP/MIME signed message (RFC 2440 and 3156)Meanwhile I read through the pcsc-lite documentation and I saw that I
need pcscd running for applications to work with the card reader. I
don't know how the /etc/pcmcia/smartcardreader-ozscr script should be
called (automatically) so had to do what it was supposed to do manually,
 that is, create the /dev/ozscrlx device node with the appropriate major
number. The /etc/reader.conf file is OK, it's from the driver and looks
like this:

FRIENDLYNAME            "O2Micro SmartCardBus Reader"
DEVICENAME              /dev/ozscrlx
LIBPATH                 /usr/local/o2micro/lib_OZSCR.so
CHANNELID               0xF10000

All the preparations done, I start pcscd in the foreground, with debug
messages turned on.

# pcscd --foreground --debug
pcscdaemon.c:259:main() pcscd set to foreground with debug send to stderr
debuglog.c:207:DebugLogSetLevel() debug level=debug
readerfactory.c:1095:RFInitializeReader() Attempting startup of O2Micro
SmartCardBus Reader 00 00.
readerfactory.c:933:RFBindFunctions() Loading IFD Handler 2.0
readerfactory.c:1130:RFInitializeReader() Open Port F10000 Failed
(/dev/ozscrlx)
readerfactory.c:1012:RFUnloadReader() Unloading reader driver.
readerfactory.c:251:RFAddReader() O2Micro SmartCardBus Reader init failed.
pcscdaemon.c:464:main() pcsc-lite 1.3.1 daemon ready.

Now I don't know that the fact that the module loads in the kernel
without warnings really means that it found a device that it was written
for or not, but this driver was originally written for PCMCIA card
readers. Now the one in my laptop is built in, but I don't know how to
find out if it connects through CardBus interface or something else.

If it's the CardBus interface, then maybe changing CHANNELID in
/etc/reader.conf will suffice (although I don't know how to find out the
exact value), but if not, the device is probably not supported by the
driver.

Any hints how should I continue the exploration of the problem?

Thank you in advance,
