    Hi Igor,

    Which version of GLSDK do you port on your omap5 uEVM?

    The latest GLSDK6.04 (http://downloads.ti.com/dsps/dsps_public_sw/glsdk/6_04_00_02/index_FDS.html) already contains the uvc_video driver, see linux/drivers/media/usb/uvc/.

    Try if enabling the v4l support in your kernel will help.

    Best Regards,

    Yordan

    Somebody can help me? How i can compile modules for ubuntu? I download "linux-headers-3.8.4" and "linux-sources",  > make config 

    #set needed modules and save modification

    > make modules    

    return infinite loop:

    make: Warning: File `/usr/src/linux-headers-3.8.4-100-omap5/arch/arm/Makefile' has modification time 1.4e+09 s in the future
    make[1]: Warning: File `scripts/Kbuild.include' has modification time 1.4e+09 s in the future

    Thanks.
