Microdia driver once working but not anymore.
Christopher Lemire
Hash: SHA1
I once had the microdia driver working with my HD Hue Webcam. I
thought maybe it would work after re-installing Linux. I recently
installed a fresh install of 64-bit Ubuntu 10.10 Maverick. I got the
latest SVN source, compiled no problems, loaded it and followed all
other instructions, and my wireless quits working (it's also plugged
in through USB). No /dev/video0 is created. I try to bring wlan0 back
up and I get
SIOCSIFFLAGS: Operation not possible due to RF-kill
So I then run "rfkill unlock all" as root, but that does not change
anything. Next I check dmesg

Each time I do this, I have to unplug the webcam and reboot Linux to
get wifi working again :(
Help please.

Could there be some usb setting in the bios I need to change? But if
that were the case, then the camera would not work in Windows either
on the same machine right?

I made some more attempts to get the driver working with the HD Hue webcam.
2nd Attempt:
I tried using a short minature usb cable. Immediately after plugging
in the cam, wifi went out. dmesg outputted the following.

Next attempt:
I blacklisted gspca_sn9c20x and rebooted.
My 64-bit system does not have a compat-ioctl32 module, but it does
have a v4l2-compat-ioctl32, so I modprobed that.

CPU usage jumped to near 100% on both cores, so I rebooted again.
Is there any other information or debugging output I can provide?
Hans de Goede
The gspca_sn9c20x driver is the upstream version of the
old out of tree microdia driver, so you should not blacklist
it. As for plugging it in causing your wifi to go away, this points
to some bigger usb subsystem problems on your machine.

Hans

What problems are you talking about? And how can it be solved. If this
is really a hardware limitation, why am I able to use the cam under
Windows 7 x86_64? So what do you suggest as the solution?
Christopher Lemire
Only thing different from these 2 is the software (driver) not
hardware I am using.

As Hans said the current driver you should be using for your camera is
the gspca_sn9c20x that is included with current kernels. I have a
camera with the same sensor as yours (MT9M111) and it works just fine
out of the box on maverick with the current kernel driver. Please
uninstall the sn9c20x.ko module and use the default gspca_sn9c20x.ko
one instead.
