[help] otg not working topic

Sir's what could be the cause if my OTG is not working..and my phone cant be detected in the PC even with PC Companion even charging..the fast few days it was working well i transferred some movies via OTG device to my phone..but yesterday when i tried to insert again my USB via OTG to my phone it cant be detected anymore and also via PC using my cable wire..now my only way on transferring files in my computer to my PC is by removing the SD card and putting it in a card reader..someone can help me with this problem?
