mounting CF card in Linux

Dear Sirs,
i recently got an OpenBrick,with a preinstalled Debian OS.
Now i have to install and tune some thinks but i don't want to damage
the CF installation. So i would like to make a copy. I have an pcmcia
adaptor for my notebook i see the card but i can't mount it. I have
enabled PCMCIA IDE support in my linux-kernel but when i insert the
PCMCIA adapter i get this error in syslog:
get dev info on socket 0 failed: Resource temporarily unavailable
Have someone an idea how i can get things work??
Thank you
Pescoller Dietrich
