TMDSCM572X: Camera module issue

Part Number: TMDSCM572X

Hi, 

The Ti AM5728 EVM camera module sometimes is detected:

/ # ls /dev/video*
/dev/video0 /dev/video1 /dev/video10
/ #

and sometimes not:

/ # ls /dev/video*
/dev/video0  /dev/video10
/ #

In fact we asked if it was a hardware or software problem. In one of this case what is the solution ?

Also I'm informing you that the items are new (about 5 days).

Best regards,
