You just need to set "CONFIG_USB_SERIAL_OPTION=m" in the kernel config and add "option" to "/etc/rc.modules" for the E220. And yes, you don't need "modeswitch" for the E220, but for many other modems. that we tested. >and finally got /dev/ttyUSB0 and /dev/ttyUSB1 devices working. > >I wrote a small dialing script using ppp and chat utility to make >sure things are OK and connection worked perfectly. > >--- >Best Regards, >Dmitry > >On Jul 28, 2011, at 16:38 , Lonnie Abelbeck wrote: > >> Dmitry, >> >> It is a lot more complicated than just enabling >>CONFIG_USB_SERIAL_GENERIC (actually CONFIG_USB_SERIAL_OPTION). >> >> The developers have played around with supporting USB 3G modems in the past. >> >> One of the problems is that these USB 3G modems are actually combo >>flash drives (by default) and USB 3G modems, "flip flop" (multiple >>device), that somehow the industry thought was a good idea. >> >> There is a Linux tool to switch "flip flop" (multiple device) USB >>gear called "usb_modeswitch"... >> http://www.draisberghof.de/usb_modeswitch/ >> >> but that has issues for us as well.
