Knoppix 5 and modem Talindus ND220

Hi! I have installed on my second hd Knoppix 5. I'm italian and I have a connection ADSL Flat of Telecom and a modem Talindus ND220. With knoppix 4 and eagle usb 2.3.2 the modem work perfectly but with knoppix 5 it don't wont to work. When I do make it show me some error. First it tell me that there is an arror in eu_main.c with 'owner' that I have solved putting /* and */. The second error is with MESSAGE_PARM with I have solved with MESSAGE_PARM_DESC(). But now there is a problem that I don't know how to solve. In the file Pipe.c at the line 922. Can someone tell me how to solve this problem? Or if there are some other drivers for my modem that work good with Knoppix 5?
Thanks!
