FC7: usb webcam not working

My usb webcam is being detected during boot-up, but it doesn't work.
lsusb :
Code:
Bus 004 Device 006: ID 0c45:602d Microdia
lsmod:
Code:
sn9c102               107981  0
compat_ioctl32          5569  1 sn9c102
videodev               30145  1 sn9c102
v4l1_compat            16581  1 videodev
v4l2_common            20033  2 sn9c102,videodev
from dmesg:
Code:
Linux video capture interface: v2.00
sn9c102: V4L2 driver for SN9C1xx PC Camera Controllers v1:1.34
usb 4-1.2: SN9C10[12] PC Camera Controller detected (vid/pid 0x0C45:0x602D)
usb 4-1.2: No supported image sensor detected
usbcore: registered new interface driver sn9c102
i guess, it is all due to "No supported image sensor detected" above.
Any ideas?

/thx/spremi

here's one that Alpha suggested in another post similar to yours - check this link out - http://www.linux.com/base/ldp/howto/...WTO/index.html and google "linux webcam drivers" - your cam might or might not be supported with a driver right now. I know mine isn't and just waiting for one right now, if it ever comes out. Cheers and happy hunting brother

Try this site http://mxhaard.free.fr/spca5xx.html for gspca driver (it supports over 200 webcams) and your vendor ID (0c45) and Vendor ID (602d) is listed there. If you prefer to use yum you can get gspcav1 from atrpms.

Sorry I wrote Vendor ID and Vendor ID. It should be Vendor ID and Product ID

webcam problem

I am also having problems with my webcam "Zippys Addons"
?Its the same "No supported image sensor detected" problem

This is the dmesg output:

usb 3-1: new full speed USB device using uhci_hcd and address 5
usb 3-1: configuration #1 chosen from 1 choice
usb 3-1: ZC0301[P] Image Processor and Control Chip detected (vid/pid 0x0AC8:0x301B)
usb 3-1: No supported image sensor detected

lsusb gives:
Bus 003 Device 005: ID 0ac8:301b Z-Star Microelectronics Corp. ZC0301 WebCam

If anyone has found a solution please tell me.
I'm not an expert and I've already spent 4 hours googling on it.

Also compling gspcav again and installing it by changing the forced sensor to something else other than Tas5130 doesnt change the output of :
/var/tmp/bach-build/BUILD/gspcav1-20070508/Vimicro/zc3xx.h: [zc3xx_config:525] Find Sensor UNKNOW_0 force Tas5130

I think the new kernel module is not loaded so it be be helpful if someone could explain how to do it.
(Running the script gspcav_build doesnt help)

Thanks in advance

Before compiling make sure you have kernel-devel and kernel-headers rpm
yuo can use:
rpm -qa | grep kernel

The correct way to install the driver is:
Download the tar.gz package
tar xzvf the package
cd to folder you extracted gspcav1-20070805
make (as normal user)
su - (to become root)
make install
modprobe gspca

In order to check if module is loaded you can run lsmod at terminal as root.
In order to check your camera I suggest you use camstream (yum install camstream).
if you had problems with compiling you can enable atrpms repo and install with yum.
Based on your information from lsusb your webcam is supported and with better image than mine (a microsoft vx-1000)

Thanks for the reply but I think it really has something to do with unrecognized image sensors.

I already had the atrpms gspcav rpm installed and camstream only gives completely blank output anf then usually ends in
QGArray::at: Absolute index 0 out of range
Segmentation fault

I was just trying to cahnge the forced image sensor type to others listed in the file
gspcav1-20070508/Vimicro/zc3xx.h: [zc3xx_config:525] Find Sensor UNKNOW_0 force Tas5130
to check if any other sensor worked
I read it at some post.
My kernel is
kernel-devel-2.6.22.4-65.fc7
kernel-headers-2.6.22.4-65.fc7
and I have installed the same gspcav rpm.

Also I want to know if I install a kernel module over an existing rpm kernel module by
rmmod gspca
#compiled gspcav1-20070508/ from source then
insmod gspca

then will this change be temporary i.e. will the original rpm module load on the next startup. (This is what I found.)
Also if not possible can I use my webcam under wine or virtualized WinXP (qemu)

Thanks again

I read else where that you should use modprobe -r and modprobe instead of rmmod and insmod but I don't remember the reason. When I was trying to make my VX-1000 work I removed the module from memory, compiled and put it back to memory without pain. And I'm sure it worked because on dmesg I could see the different module loading. But you could unplug the camera, reboot, compile and reinstall just in case.
Forgive me, if you think I am repetitive, but perhaps you could give atrpms a chance. I noted no difference between general behaviour and image quality when using its rpm package or compile on my own computer.

Thanks so much for taking care to reply but I think I did not make it clear that I had installed the atrpms package (and it wasnt working) before trying to compile and install (by changing the sensor type in the file Vimicro/zc3xx.h to see if that worked). I think my webcam sensors are not supported and I'll have to get another one. I've reinstalled the gspca rpms from atrpms and it still doesnt work

Thanks again for taking the trouble.

dmesg:
usb 3-1: new full speed USB device using uhci_hcd and address 4
usb 3-1: configuration #1 chosen from 1 choice
usb 3-1: ZC0301[P] Image Processor and Control Chip detected (vid/pid 0x0AC8:0x301B)

usbcore: registered new interface driver gspca
/var/tmp/bach-build/BUILD/gspcav1-20070508/gspca_core.c: gspca driver 01.00.18 registered

Maybe I'll wait till the sensors are supported

From this site
http://zc0302.sourceforge.net/zc0302.php?page=tools
Ok So I've checked in Windows,
Using RegMon and the sensor is TAS5130C
But still I get a blank screen (Completely black output) on camstream, mplayer, xawtv and spcagui.
So I've no clue how to make it work.

Anyways thanks for all your replies.

Just to let you know I got a zstar vimicro zc0301p camera up and running after
installing gspca rpm AND importantly blacklisting the zc0301 driver in /etc/modprobe.d/blacklist.

I'm using FC8 since last month, everything works fine except usb webcam (v-gear), after going through this thread, i did lsusb and got following msg:

$ /sbin/lsusb
Bus 001 Device 001: ID 0000:0000
Bus 002 Device 003: ID 0c45:6100 Microdia
Bus 002 Device 002: ID 045e:0084 Microsoft Corp. Basic Optical Mouse
Bus 002 Device 001: ID 0000:0000
$

http://mxhaard.free.fr/spca5xx.html used to find-out whether 0c45:6100 (vendor id : product id) is supported or not, only vendor id (0c45) matched / listed, does this mean my usb webcam is not supported?

Any help on this much appreciated.
Thanks
