problem with usb camera

Hi,

I have some trouble with getting usb camera to work. I configured kernel with UsbHost following the document in http://nioswiki.jot.com//wikihome/operatingsystems/usbhost (http://nioswiki.jot.com//wikihome/operatingsystems/usbhost)

In kernel menuconfig,

turn on scsi device, scsi disk

turn on host-side usb, usb dev fs, your hcd, usb device eg mass storage.

File systems -->

DOS/FAT/NT Filesystems --->

[*] MSDOS fs support

[*] VFAT (Windows-95) fs support

(437) Default codepage for FAT

(iso8859-1) Default iocharset for FAT

Native Language Support -->

(iso8859-1) Default NLS Option

[*] Codepage 437 (United States, Canada)

[*] Simplified Chinese charset(CP936,GB2312)

Besides,I configured more other thing for my usb camera

Device Drivers -->

Multimedia devices-->

<*> video For Linux

USB support-->

<*> Support for Host-side USB

...................

[*] USB device filesystem

...................

<*> ISP1362 HCD support

...................

<*> USB Mass Storage support

....................

<* > USB OV511 Camera support

then make ,make linux image ,download the zImage into DE2 board. insert the usb camera,the kernel detect the camera as follow:

Uncompressing Linux... Ok, booting the kernel.

    Hi,

    Is there nobody to use Usb camera on DE2 board?

    In ISP1362 DateSheet ,it said that ISP1362 support all four type of USB transfers:control,bulk,interrupt,ISOCHRONOUS., and it also support transfer at full-speed and low-speed(not high speed). But the ISOCHRONOUS transfers are defined only for full-speed and high-speed. So it means that in ISO transfer type,we can only use full-speed.

    In isp1362-hcd.c, line 1307 (function isp1362_urb_enqueue): 

    if (type == PIPE_ISOCHRONOUS) {
  ERR("Isochronous transfers not supported\n");
  return -ENOSPC;
    }

    So when i run test app: 

    #include <stdlib.h># include <stdio.h># include <sys/types.h># include <sys/stat.h># include <fcntl.h># include <unistd.h>
int main()
{
    char devname = "/dev/video0";
    printf("Begin device open test......\n");
    printf("Device name: %s\n", devname);
    int hf = open(devname, O_RDWR);
    if(hf < 0)
    {
  perror("Device open test ERROR! : ");
  exit(1);
    }
    close(hf);
    printf("Device open test OK!\n");
    return 0;
}

    The error message like this: 

    />devopen
Begin device open test.......
Isochronous transfers not supported
deriver/usb/media/ov511.c:init isoc: usb_submit_urb<0> ret -28
Device open test ERROR! : : No space left on device
/>

    So i mask the code: 

    //if (type == PIPE_ISOCHRONOUS) {
  //ERR("Isochronous transfers not supported\n");
  //return -ENOSPC;
    //}

    Then the erro message like this: 

    />devopen
Begin device open test.......
Device name: /dev/video0
start_iso_transfers:Not enough ISO buffer space for 1023 byte PTD

    So I puzzled .......if ISP1362 support ISOCHRONOUS transfer, Why the error happened? Is it because the urb->dev->speed ?

    Is there anyone facing the same problem? Pls give me some advice.

    Thanks

    Excuse me!

    I just want to known where you get the isp1362 driver programmer?I douted that the isp1362 driver programmer which generate the problem.and i want to know which usb camera you use? ....the webeyev2000 ,v3000.

    i realy want to chang a type of camera,but i don&#39;t known which camer support the chip of SE401,IBM xirlink,SN9C10x,STV680,konica webcam...

    Would you please connect with me ,we can comunicate with each other.

    Leewood,

    sorry for late reply. I had been very busy.

    I did not know isp1362 well. I am better on isp1761.

    They should be similar.

    You are right. It is possible to use isp1362 for isochronous transfer.

    Most of the code are there.

    There might be some bugs. You may look at the other chipset to find out how they work for iso.

    You can find out the error from the source.

    I think NPX (philips semi) have the driver. Maybe you can check with them.
