minimum requiremet for hsfmodem

Hello,

I'm working on an "embedded" Linux system that should fit on a Compact 
Flash 64Mb. The system is read-only and have to use a Conexant 
softmodem. I prepared the package hsfmodem on a complete Linux 
distribution and take binaires and config file to put on the embedded 
system. However, I still have some trouble:

- After boot start, hsfconfig does not detect the hsfmodem even if it 
exists in /proc/bus/usb/devices. I need to unplug and plug the modem 
before it is detected by hsfmodem driver.

- when hsfconfig -i detects the modem, hsfconfig asked me for email and 
Id which it didn't do on the development host and finished with "ERROR".

- I can't unload and reload hsfmodem module. It crashes the system at 
reload.

I think I miss some dependencies. What are the minimim requirement to 
make hsfmodem driver working? What do I do wrong?
I can provide you the dumpdiag but here is the USB status while hsfmodem 
is not detected by hsf driver. and hsfconfig -i output:
