I also have the same issue on Lucid and no solution.
So far I am using Windows 7 in a Virtual Machine which is of course not
the preferred way out.

Hey guys, we're still waiting for a solution out here. Expiring it
because nobody there is doing anything about it would seem to be a bit
wrong.
The problem still exist with lucid and maverick.
I have tried it with a backport linux-
I have removed the nvidia driver (installed and uninstalled via the
hardware drivers utility system-administration) and the system is using
nouveau drivers.
Webcam back to normal from restart and from cold boot. (so far, touch
wood, after 4 restarts)
Also cpu usage is lower with nouveau than
Nvidia is not the problem. Problem eventually re-surfaces after a cold
boot, but subsequent warm boots/restarts can fix the problem. I have
reinstalled nvidia, and webcam is working OK with nvidia driver. (as
above, except after cold boot).

Kim, please keep going on this! It affects me to and I would be sooo
happy if it can be resolved somehow.

I have recompiled a new kernel grom the git tree - 2.6.32-25, with the
only configuration change being the drivers ehci_hcd and uhci_hcd being
module instead of in the kernel.
By rmmod ehci_hcd followed by modprobe ehci_hcd, the webcam sometimes
springs into life. (and sometimes not)
By removing
Have tried using rmmod / modprobe as above when webcam fails, but am now

After being up for a while with the webcam working, a lost interrupt has
caused the webcam to re-initialize and fail.
from /var/log/messages :-

There seems to be no consistent way of making the webcam work repeatedly
across reboots. Sometimes it connects at 480Mbps, and works correctly
at all resolutions, sometimes at 12Mbps and only works correctly at low
resolutions, (higher resolutions get a lot of green lines splattered
across video,
After adding some packages yesterday to maverick (nvidia driver, compiz,
etc) and adding any updates, I rebooted again today into maverick, and
the webcam works!
Rebooted from cold, and webcam failed again.
I'll have a look at whether cold boot or reboot from different versions
of ubuntu cause
hmmm. it seems there is no consistent answer, except that the
webcam etc works depending on the startup time - it is looking like a
timing problem. Perhaps the webcam etc is initialized too soon, before
it is ready?

I toggled the /etc/default/irqbalance ENABLED=... in both lucid (1=0)
and maverick(0=1), and the webcam is now working in both, although the
picture is shot thorough with green horizontal lines and breaking up
badly.
This is the first time that the webcam has worked in lucid, apart from
