[Muscle] EHStatusHandlerThread() Error communicating to reader

[Sean]

Hi,

I am using an Omnikey CardMan 5321 on Debian Etch. I am using 
pcsc-lite-1.5.2 compiled with --disable-libhal --enable-libusb 
--enable-extendedapdu. I also have undefined ADD_SERIAL_NUMBER in 
hotplug_libusb.c per the Omnikey ifdokrfid_lnx-2.6.0 README.

I am using driver version ifdokrfid_lnx-2.6.0. Kernel 2.6.23.

I am using pcsc_scan 1.4.8 in pcsc-tools.

Card ATR: 3B 8F 80 01 80 4F 0C A0 00 00 03 06 03 00 02 00 00 00 00 69
I believe this is a Mifare 4k card.

Contactless card scanning works fine for a while. Then after 20 minutes 
to several hours I see this from pcsc_scan:
Reader 0: OMNIKEY CardMan 5x21 00 00
Card state: Status unavailable,

At that time I see these messages in /var/log/messages starting. They 
continue until I either unplug the reader or restart pcscd. What do you 
think is going on here? I am willing to try anything.
