Hello Lonnie, I have successfully configured HUAWEI E220 USB 3G dongle under Astlinux.
CONFIG_USB_SERIAL_OPTION and CONFIG_USB_SERIAL_GENERIC options in kernel config make it work. Actually I think that only CONFIG_USB_SERIAL_GENERIC is required. Dongle works OK without loading of option.ko module but this may be my particular case. No 'combo' switchers required. So I think enabling those kernel options by default in Astlinux would be a good idea. At least this should not hurt anything else in Astlinux, so why not?.. Another question is how to integrate this 3G connection into Astlinux the right way (both in the GUI and in the boot scripts) to make sure all the things are consistent. Is it possible to include the 'wvdial' utility into the build tree? It is much more convenient and reliable way to manage 3G connections than ppp and chat scripts. FYI, this is what I actually did (I'm not a Buildroot2 expert so there should be the right way): 1) svn co https://astlinux.svn.sourceforge.net/svnroot/astlinux/branches/0.7 astlinux-0.7 2) disabled some packages which prevented my system from compiling at first run and completed the build process 3) modified kernel .config file to have CONFIG_USB_SERIAL_GENERIC and CONFIG_USB_SERIAL_OPTION enabled 4) issued 'make clean' from the kernel tree and rebuilt the system again 5) I had problems running the makerunnix.sh script so I simply replaced runnix and os files on my existing CF card with ones from build_i586/runfs/ directory When my system booted I loaded the usbserial module with required parameters: modprobe usbserial vendor=0x12d1 product=0x1003 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.
