Hi Raiko
Sounds like you are having problems with using this device.
Never tried 1 myself but wonder if it come with extra drivers for Windows? If it does then it probably will not work with any OS that the extra drivers are not available for.
Looking at the model data available here
http://www.hidglobal.com/technology.php?tech_cat=19&subcat_id=10&headerType=1 I would guess that it will not work with eCS (OS/2) - but I'm happy to be proven wrong.
What happens when you attach the device? - Does the Removable USB drive monitor let you know it is attached?
What size card are you using in the device? - anything over 2Gb needs to be made into an LVM volume before it can be used.
Regards
Pete
