Lain, First the Agere code is now several years since an official Agere/LSI update of the Linux code, and if it works on anyones PC, we are lucky. Secondly, in your particular case, there seems to be a conflict between USB and modem functions. If it is possible for you to completely disable USB functions while using the modem, I can walk you through how to work that out. More broadly, you would best off achieving a non-modem COMM modality. For disabling the USB sector, Physically remove as much USB hardware/devices as possible. There may be some internal USB bridges which cannot be removed. The folowing procedure is basically to display cogent drivers with: $ lsmod | grep usb Starting from the top of the list and working down, unload these drivers with: $ sudo modprobe -r DriverName Checking for success with: $ lsmod | grep usb When all are removed, you can then again test for modem functionality. Good luck & report back MarvS scanModem maintainer
