D-Link USB modem

[Kyle Marcus Anderson]

Hi all,

I have D-Link's DSB-560, a USB modem that is supported with the acm driver.
I am running Red Hat 7.1 with kernel version 2.4.2-2.

modprobe acm
lsmod - where
mknod /dev/usb/ttyACM0 c 166 0
ln -s /dev/usb/ttyACM0 /dev/modem

/proc/bus/usb/devices gives

I have read the man page for acm and loaded the acm, usbcore, and usb-uhci
modules.
They are loaded , correct? but the /proc/bus/usb/devices doesn't load my modem
or the
driver in the list... I have had luck with running a USB audio device but have
had no luck with
my modem as of yet.

The other thing I noticed was that I can't find out whether I actually have ppp
support.  there is
no sign of it under linuxconf >  Networking > client tasks. when I try to
activate ppp0 under netcfg >
interfaces it returns "Failed to activate ppp0 with error 7".

any help would be appreciated.

Thank you,

Kyle
