Nothing else that would use the camera is running, "lsof /dev/video0"
also confirms that. I've tried 2 other USB webcams, gspca and ov51x,
both work fine.
It's either broken hardware or something strange in code. I've run both
strace and gdb against luvcview, no more information. xawtv also gives
EBUSY. I'm restoring XP to another HD to see if I get problems there also.
Regards
Sid.
