Hi All, Sorry for the late response, for I am on Qingming Festival for the last 3 days. I noticed Ritesh has tried a USB sensor, I do not have that kind of sensor at hand and have not tried it yet. My patch worked well for ISH but I am not sure whether it is fine for USB sensor. Sorry for not much information can provide. I will try to see if I can find one device and try.
