usbcam.dll driver is not attached when I pluged the USB camera(UVC) on WINCE6.0 RRS feed

  • Question

  • I installed  and compiled usbcam.dll correctly and made new image for test.

    I confirm that usbcam.dll and jpeg2rgb.dll is in \\windows folder and usbcam.reg and jpeg2rgb.reg is registered in registry.

    but when I pluged the usb camera, the message box appeared in order to find the driver.

    what should i do ?

    my product is S5PC100 and wince6.0 based, USB host work with USB disk and USB lan and USB gprs modem well.

    Thank you in advance for your kind answer.

  • Did you verified the contents of the usbcam.reg file exists in the device using any of remote tools or by looking into file?

  • Thank you for your kind reply.

    I added the contents of the usbcam.reg into platform.reg before making ce image and I verified it after downloading new kernel by running regedit.exe on my product which have 7 inch LCD.

    Best regards,

  • Ok Cool.
    And i hope your USB web camera is a video class complaint.So here are the other options to check,
    * Can you build the debug version and check enabling the debugzones for USB host while inserting the camera to the USB port? Post the log here.
    * Make sure to check the bib entry for the 'K' flag in the usbcam driver entry.

  • Thank you,

    when I pluged this camera into my windows xp notepc, I can find "Compatible ID" as "USB\Class_0e&SubClass_03" in hardware manager.

    Is this Video class compliant?

    In case of Platform.bib file, I added driver like below :

    usbcam.dll         $(_FLATRELEASEDIR)\usbcam.dll          NK      SHK

     jpeg2rgb.dll         $(_FLATRELEASEDIR)\jpeg2rgb.dll          NK      SHK

  • Hi James,
    Could you build a debug version of the image and try to capture log messages while inserting the camera?
