To verify that it is not a constatus-problem I also tried a raspberry-pi camera via its video4linux-interface and that works fine.
According to the Linux Kernel Maintainers file the device driver is
maintained by Hans, which I CC'ed on this bug report:
GSPCA PAC207 SONIXB SUBDRIVER
M: Hans Verkuil <hverkuil@xxxxxxxxx>

Did your camera ever work on another Kernel, CPU architecture, or
v4l-utils version? Do you have anything suspicious in dmesg output?
Thanks,
Gregor
