That is probably not a modem issue but rather due to the kernel 2.4.x. Check
Joss Winn's Re: Pre-compiled 2.4 kernels? in this list.
"...I've been using the suse kernels with no problems. The 2.2.18 rpm was a
breeze, the 2.4.x gave me module problems until I worked out the new
names given to some kernels (ppp/dmasound...) and changed
/etc/modules.conf accordingly. Also, with the 2.4.x you need the new
modultils and the new ppp, both available with the kernels on the suse site.

Subject: Ricochet usb modem? Pismo powerbook usb support?
Here comes post #2 for the day. =]
Anyone have suse 7.0 running up-to-spec on a pismo powerbook? I'm having
great trouble with a usb modem. I tried upgrading the kernel to 2.4, etc.
It's a ricochet wireless modem, it uses standard AT modem commands. It will
dial and so fourth, but pppd craps out when wvdial tries to fire it up.
Any help is greatly appreciated,
