USB ACM device is not recognised in overo

[ymkim92]

I am running new kernel of 3.17.8 in overo:

root@overo:~# uname -a
Linux overo 3.17.8-custom #1 SMP Fri Mar 27 20:51:48 AEST 2015 armv7l GNU/Linux

I cannot find cdc_acm module using lsmod and 'modprobe cdc_acm' did not work.
This is the output as I push it to the USB port.

modprobe cdc[ 2243.645111] usb 1-2.4: new full-speed USB device number 6 using ehci-omap
[ 2243.777465] usb 1-2.4: New USB device found, idVendor=2341, idProduct=0010

[ 2243.804199] usb 1-2.4: SerialNumber: A4830363438351314041

There should be one more line like this:

[   30.175445] cdc_acm 1-2.4:1.0: ttyACM3: USB ACM device

After I add cdc_acm module into Kernel as "M", it is working!
Using this command:

bitbake -c menuconfig virtual/kernel

I pushed the corresponding change to the meta-gumstix branch. gumstix/meta-gumstix@ba1ddd0
