With Knoppix 3.4 my usb modem is working ok and is identified as /dev/usb/ttyACM0. Using Knoppix 3.7 and the Linux26 kernel I am unable to access the modem so far. I have searched high and low, but cannot find the device the kernel is using. The module cdc-acm is loaded. The program Usbview shows full details of the modem. If I cat /proc/bus/usb/devices I get to see details of the modem, but no reference to the usb device it is accessing. Dmesg just shows one line saying it has found some hardware, but nothing else. I have not looked at /var/log/messages - it is not running at boot anyway.
Can anyone help ?
I wonder if all of the correct usb modules are loaded for Linux26 ?
