How to add module usbserial

Former Member over 11 years ago

I want to attach the mobile-modem Huawei E-169 and an USB-RS485 adapter.

Both devices are listed in lsusb.

but no one will be mounted correctly

The Huawei Modem should be mounted at /dev/ttyUSB*.

dmesg delivers output only mounted as storage.

I tried to modeswitch the device with modeprobe usbserial with following error.

FATAL: Module usb_serial not found.

How can i load module usb_serial?

linaro@linaro-ubuntu-desktop:~$ modprobe -l | grep serial

kernel/drivers/usb/gadget/g_serial.ko

already tried to /boot/linux.config

CONFIG_USB_SERIAL=y and

CONFIG_USB_SERIAL=m

Working on Ubuntu 12.11

There appears to be very few modules included in the default image. I don't see the usbserial one.

So you're left with following the instructions radiatortwo posted on recompiling that kernel, but while you're configuring it you can add any missing modules you think you'll need

as mentioned by agrahambell you can recompile the kernel, however you can give the below just-a-try to check if it works.
i have got a number of usb devices working on X86 (not arm) by just changing modeswitch .

goto module build directory "lib/modules/<kernel version>"
execute below comands with your PID VID & check if its has a supported module.
cat modules.alias | grep [PID]
cat modules.alias | grep [VID]

try this also
in "/etc/usb_modeswitch.conf"
change DisableSwitching from "0" to "1",
this ensures the USB default mode is not activated.

fairly sure the entry won't be in modules.alias if the module was never built, but sure it's worth a try.

I downloaded the e14 Ubuntu image and there appears to be so few modules included that lots of people are going to have problems.. Only a single wifi module included sticks out as being a really strange choice
