It isn't the cam importer which detects the stick it is the box. If the cam importer can't see the stick it normally means the box can't see it or the mounts have not sorted themselves out.
If you press the blue button and then the yellow button, can it see two devices? If so are they mounted as /media/hdd & /media/usb?
Yes the 2 sticks are recognized by the box
stick for recording in the back usb port is /media/hdd
stick with cccam.cfg file in front usb port is /media/sdb1
still wont read tho.
