I couldn't find any with the search engines. But I found that the Jabra Panacast (which is an "ePTZ" camera) needs this patch also, it has the following controls: pan_speed 0x009a0920 (int): min=0 max=10 step=1 default=5 value=0 tilt_speed 0x009a0921 (int): min=0 max=10 step=1 default=5 value=0 Regards, Gergo
