Bug Description

While trying to get libcec working it seems that the usb driver for CDC-ACM is not available in the kernel nor as a module, my effort to find the source code of the kernel 3.1.1-8-linaro-lt-omap armv7l is unsuccessful.

This driver is needed to make the USB HDMI CEC adapter to work (allow to use the remote control of the TV to control the XBMC), could you please make it available as a module in the future release of the Linaro TV - XBMC.

Some more information :

on the site :

we can read :

libCEC needs the following dependencies in order to work correctly:
* udev v151 or later
* cdc-acm support compiled into the kernel or available as module

for udev it's OK but we need the module cdc-acm and the one I compiled using :
sudo apt-get source linux-linaro-lt-omap gives me
vermagic: 3.1.5 SMP preempt mod_unload modversions ARMv7 and not
vermagic: 3.1.1-8-linaro-lt-omap SMP preempt mod_unload modversions ARMv7

so right now my test fails.

Thank's for your help.
