Hi,
You need to use libv4l and have your apps patched
to use libv4l or use the LD_PRELOAD wrapper.
Here is the latest libv4l:

And here are install instructions:

Hello,
I'm having a problem with a (cheap) Trust USB webcam I bought yesterday.
It works fine under Windows XP.
The device is:
ID 093a:2460 Pixart Imaging, Inc. Q-TEC WEBCAM 100
For Linux I've found that it is recognized by the gspca_pac207 driver.
But opening the video device using xawtv or vlc shows nothing.
Problem seems to be that after I plug it in the led on the device goes
on, but after a very short time (less than a second) it goes out again.
When I plug it in (after a clean boot), dmesg shows:
usb 1-2.1: new full speed USB device using ehci_hcd and address 7
Linux video capture interface: v2.00
gspca: main v2.8.0 registered
gspca: probing 093a:2460
pac207: Pixart Sensor ID 0x27 Chips ID 0x09
pac207: Pixart PAC207BCA Image Processor and Control Chip detected (vid/pid
0x093A:0x2460)
gspca: video0 created
usbcore: registered new interface driver pac207
pac207: registered
And the following (extra) modules get loaded:
Module Size Used by
gspca_pac207 6021 0
gspca_main 22454 1 gspca_pac207
videodev 37424 1 gspca_main
v4l1_compat 12201 1 videodev
v4l2_compat_ioctl32 9867 1 videodev
I'm running 2.6.33-rc8 (x86_64) on a Debian stable ("Lenny") system.
Kernel config, relevant contents from /sys/kernel/debug/usb/devices and
output from v4l-info attached. Some other info below.
This is the first time I'm trying a webcam, so it may be that I'm missing
something obvious. I googled around a fair bit, but nothing I tried helped.
Any help would be appreciated. I can provide any additional info that's
needed and test any kernel version.
Cheers,
FJP
