infinity USB Phoenix crash – debian

I have a problem with my CCcam and my infinity USB
Indeed I had a siemens station, while I installed debian, CCcam and infitniy USB
everything works perfectly.
I just migrated to a HP station, I redo the same thing, everything works except for the Infinity USB Phoenix who works for a certain period and then it gives me this error:

card reader / dev/ttyS0
No or unknown card inserted

M config
HP Prolian ML 100 – Debian lenny 5.03 x86
CCcam 2.1.2
Infinity USB phoenix

after reboot, try this command in terminal
