FC4下CDMA手机驱动的一个很奇怪的情况！求助！
小弟初学linux，上不了宽带，只能用CDMA手机上网。第一次装好FC4后，怀着激动的心情联上手机。察看/var/log/message

一看不对。网上流传的文章中说message中应出现
hub.c: new USB device 00:07.2-1, assigned address 2
usb.c: USB device 2 (vend/prod 0x4e8/0x6601) is not claimed by any active driver
usb.c: registered new driver acm
ttyACM0: USB ACM device
acm.c: v0.21:USB Abstract Control Model driver for USB modems and ISDN adapters
死马当活马医了。启动Kppp。设置modem为/dev/ttyUSB0结果不行。继续尝试/dev/ttyUSB2成功！！
一阵喜悦，可第二天再次启动Kppp拨号，结果显示modem不存在。
察看/dev ttyUSB0，1，2，3都没有了。
察看/var/log/message出现
localhost kernel: IPv6 over IPv4 tunneling driver
localhost kernel: cdc_acm 3-1.1:1.0: ttyACM0: USB ACM device
localhost kernel: usbcore: registered new driver cdc_acm
localhost kernel: drivers/usb/class/cdc-acm.c: v0.23:USB Abstract Control Model driver for USB modems and ISDN adapters
是出现ttyACM0了，可kppp中没有/dev/ttyACM0 这个选项啊 不知该怎么弄。
运行ln -s /dev/ttyACM0 /dev/modem
Kppp中选择modem为/dev/modem
结果提示启动modem，modem无响应。
反复重启几次后发现，手机大部分情况下被驱动为ttyACM0，这时我就不知道该怎么上网了。
有时运气好手机被驱动为ttyUSB0，1，2，3时。选择modem为/dev/ttyUSB2
就可以上网。
在网上搜了一下，ttyUSB0，1，2，3好像是用来驱动palm的
即使mknod /dev/ttyUSB0,1,2,3 也不能拨号。
真的很奇怪，为什么是一部手机能被驱动为不同的设备呢？
希望高手帮忙解决问题。
我的手机是三星X659
主板为SIS芯片
