Okay, that might be some problem with my camera. The light at the back of
SR3000 is always red, maybe there's some problem. I am trying SR4000, it's
atleast connected to the device. I get the below messages. One message I
want to know more about is error obtaining child information: Inappropriate
ioctl for device
The good thing is it atleast says it's connected unlike the SR3000. Should I
be changing anything in my launch or mesa.rules file? Thank you.
