USB 3G on ARM board Debian - not loading ttyUSBx serials
Hi, Im trying to interface a 3G HUAWEI K3765 dongle, but no success yet.
The dongle is recognized but does not load the ttyUSBx serials needed to interface it
It seems that the default kernel is not loading the modules needed to USB 3G dongle operation
For example in other ARM embedded system that I have, when I plug USB 3G I get this active modules
Module Size Used by
option 17181 0
usb_wwan 11325 1 option
usbserial 32142 2 option,usb_wwan
There are this 3 modules loaded for 3G dongle operation
But in this board this modules are not loaded
Somewhere I read also that it will be needed "option" compiled in as a module into kernel.
If I try to manually load this module I get this
debarm:~# modprobe option
FATAL: Module option not found.
Any ideias to activate this "option" module?
When you plug in the dongle, a message or two in the syslog (possibly /var/log/messages) should appear, indicating which USB-Serial chip is used in your dongle. From there it should be easy enough to determine which driver applies, and load it manually. It is possible that the device is not supported in Linux, or that the driver was not built or supplied with your kernel. If you cannot interpret the syslog messages post them here (in [CODE] [/CODE] tags, please). Someone here should be able to recognize the appropriate bits.
Had to compile kernel from source and add USB driver for GSM and CDMA modems support
