In a hard disk I have Ubuntu 8.10 kernel 2.6.27-14 and there modem run well. I installed the new release 9.04 in a new HD and before delete old I tried to install modules for modem into new. But I haven't chance. I installed: libasound2-dev sl-modem-source sl-modem-daemon but when I read lsmod there is only slamr module not ungrab-winmodem. I tried: ciornj@deskubu904:~$ sudo modprobe ungrab-winmodem debug=3 [sudo] password for ciornj: FATAL: Error inserting ungrab_winmodem (/lib/modules/2.6.28-18-generic/updates/dkms/ungrab-winmodem.ko): Unknown symbol in module, or unknown parameter (see dmesg) ciornj@deskubu904:~$ dmesg | grep ungrab-winmodem ciornj@deskubu904:~$ dmesg | grep slamr [ 14.767920] slamr: module license 'Smart Link Ltd.' taints kernel. [ 14.776133] slamr: SmartLink AMRMO modem. [ 14.776166] slamr: device 10b9:5459 is grabbed by another driver Can anyone help me? Or I must stay all time with old release. Arturo
