    leo_ietres, can you tell me specifically how you did that?

    I also have a Packard Bell Easynote BG45-P-025 and cannot solve the problem.

    I'm running Ubuntu 8.04 64bits.
    Image is seen in the right position in cheese (but too dark). Ekiga and Skype still show upside down. (I've tried all 4 solutions).

    Thanks

    Hi WillyLinux,
    are you getting any error while installing the patch/module?

    It seems that the patch isn't applied and used...try to restart your system!!

    hi arjos85,
    everythink seems to be working (at least I don't receive any warning or error).

    Steps:
    1.download files
    2.change files makefile INSTALL_MOD_DIR := usb/media/usbvideo
    3.download patch and copy to trunk folder
    4.patch < filename

    guillermo@rtpc:~/descargas/trunk$ patch < patch_solution1_mirrored.txt
    patching file uvc_video.c
    guillermo@rtpc:~/descargas/trunk$

    (no error message. seems to be ok).

    5.make

    guillermo@rtpc:~/descargas/trunk$ make
    Building USB Video Class driver...
    make[1]: se ingresa al directorio `/usr/src/linux-headers-2.6.24-19-generic'
    CC [M] /home/guillermo/descargas/trunk/uvc_driver.o
    CC [M] /home/guillermo/descargas/trunk/uvc_video.o
    LD [M] /home/guillermo/descargas/trunk/uvcvideo.o
    Building modules, stage 2.
    MODPOST 1 modules
    LD [M] /home/guillermo/descargas/trunk/uvcvideo.ko
    make[1]: se sale del directorio `/usr/src/linux-headers-2.6.24-19-generic'
    guillermo@rtpc:~/descargas/trunk$

    (seems to be no error)

    6.7.8.

    guillermo@rtpc:~/descargas/trunk$ sudo modprobe -r uvcvideo
    [sudo] password for guillermo:
    guillermo@rtpc:~/descargas/trunk$ sudo make install
    Installing USB Video Class driver...
    make[1]: se ingresa al directorio `/usr/src/linux-headers-2.6.24-19-generic'
    INSTALL /home/guillermo/descargas/trunk/uvcvideo.ko
    DEPMOD 2.6.24-19-generic
    make[1]: se sale del directorio `/usr/src/linux-headers-2.6.24-19-generic'
    guillermo@rtpc:~/descargas/trunk$ sudo modprobe uvcvideo
    guillermo@rtpc:~/descargas/trunk$


    Something has been solved as in the camera software "cheese" the image has turned to normal position (but dark). In the other software there's no change at all.

    Perhaps I'm forgetting something or applying something wrong?
    rebooting the system doesn't change anything.

    thanks!

    well... I really don't know!!

    Try this steps:
    Code:
    sudo find /lib/modules/ -name uvcvideo.ko  (give me the output)
    sudo modprobe -r uvcvideo
    sudo rm `find /lib/modules/2.6.24-19-generic/ -name uvcvideo.ko`
    sudo make install
    sudo cp uvcvideo.ko /lib/modules/2.6.24-19-generic/usb/media/
    sudo depmod -ae
    sudo modprobe -f uvcvideo
    Let me know,

    Re: [HOW-TO] Upside-down image from UVC webcam

    It worked!

    I've tried what you suggested and it worked (Ekiga works fine and Skype can transmit video properly -even tough I cannot see my own video in Skype, but this is a Skype matter I guess) another comment: cheese is not working after the changes, I removed it.

    I don't know if the output you requested is useful now, but here it is:
    /lib/modules/2.6.24-16-generic/ubuntu/media/usbvideo/uvcvideo.ko
    /lib/modules/2.6.24-19-generic/usb/media/uvcvideo.ko
    /lib/modules/2.6.24-19-generic/usb/media/usbvideo/uvcvideo.ko

    Well, thanks a lot!
    Regards

    congratulations man!!! it works perfectly... now no need to have windows vista any more just for the webcam...
    only the speed is very slow but I guess this will be improved in the general driver!

    thanks a lot once more.
