I have an USB camera that has a 5Mp sensor in it. But the device works only as a 1.3Mp sensor (via 2x2 binning or skipping). The 5Mp sensor is most certainly there (when plugging the device to a windows machine before installing the drivers it reports as a CMOS color 5Mp sensor), but I don't know if the limitation is software based (e.g. via firmware) or hardware based (e.g. a different hw interface between the sensor and the computer). If it matters, the sensor is a Micron MT9P031. Anyway, is there any easy way of knowing if the camera can be hacked to use the full potential of the sensor? thanks,
EDIT1: According to http://www.tucsen.com/Public/upload/download/pdf/Software%20and%20Driver%20download%20links_EN_20210922.pdf the models in question hava a vendor ID VID:0547 and product ID PID:A008 and PID:A004 (for the 1.3Mp and 5Mp respectively) I can confirm I have the A008 PID. Furthermore, this information is lso available in the INF file:
%VID_0547&PID_A008.DeviceDesc%=TuUsb3, USB\VID_0547&PID_A008 ; ISH130 %VID_0547&PID_A004.DeviceDesc%=TuUsb3, USB\VID_0547&PID_A004 ; ISH500
