Probleme with USB Cardreaders


Hi.

I have installed Unbuntu 6.06 Server and running a cardserver (newcs.x86) with 2 cardreaders (MP3.6USB).
It works fine for 30min, then ttyUSB0 or ttyUSB1 gets disconnected, and becomes ttyUSB2...then after 30min, ttyUSB2 get disconnectet, and ttyUSB0 or ttyUSB1 gets connected again. Here you can see the log:

Sorry you can't remember ... I have been struggling with this problem for a long time ...

Before Linux (I have thrown Windows out of the window) I had the same cardreader hooked to a Windows server and it also worked OK ... so I suspect it is a Linux problem ...
Do you remeber if you solved it bye yourself or did you get some help from any forum ?

Anyhow ... Merry X-mas to you !
