Dear Friends,
I'm try to use - Modem 3G - Olivetti 145 and HUAWEI E5832 -
i'm very frustrated :) After a while of kernel compiling and when i thougth to
solve all my problem with driver modules KO.

When i try to activate PPP Stack i have an out of stack on ppp_generic modules
:(

So i compile using PKGBUILDING all neded module.
I recompile the usserial for support my usbserial generic husdpa module. If i
try it with minicom , all work fine , the module reply and i can connect the
network the usb available is ttyUSB4 , i use modem_switch to choose the 3G
module instead of mass storage and also that is ok, but the when the script try
to up the ppp_generic module this is the debug of error.

So i solved also a power problem , a 3g module need more current for works so
the power supply from Olinuxino Maxi is not enought to power up the Internet key
, when there is a connection with the network the Olinuxino reset it self and
rebooting. I need to put on usb a power usb 4 port router , so now i haven't the
problem of reboot ...

I need your help please :)
