[Bug 41779] webcam error - ov511.c: No decompressor available

[Miguel Gaspar]

Public bug reported:

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
Contrary to Ben Collins' status explanation, regarding bug #3717:
<quote>This is fixed in dapper, but will not be fixed in breezy.</quote>
, this bug still occurs in dapper, at least in the first beta. I tested with live-cd kubuntu, with the exact same problem.

Steps to reproduce:
Connect Philips ToUcam model 720K/00; syslog reports
Apr 27 18:53:30 localhost kernel: [4295842.790000] usb 1-1: new full speed USB device using uhci_hcd and address 5
Apr 27 18:53:30 localhost kernel: [4295842.918000] drivers/usb/media/ov511/ov511.c: USB OV518 video device found
Apr 27 18:53:30 localhost kernel: [4295842.919000] drivers/usb/media/ov511/ov511.c: Device revision 1
Apr 27 18:53:30 localhost kernel: [4295842.931000] drivers/usb/media/ov511/ov511.c: Compression required with OV518...enabling
Apr 27 18:53:32 localhost kernel: [4295844.276000] drivers/usb/media/ov511/ov511.c: Sensor is an OV6630
Apr 27 18:53:32 localhost kernel: [4295844.479000] drivers/usb/media/ov511/ov511.c: Device at usb-0000:00:1d.0-1 registered to minor 0

The device appears in Device Manager, wich reports
video4linux.device: /dev/video0

Then do 
cat /dev/video0

syslog says
Apr 27 18:57:20 localhost kernel: [4296073.038000] drivers/usb/media/ov511/ov511.c: No decompressor available
