Need help, LarkBox USB stopped working

Hi, i’ve had my Larkbox for a while with only an air mouse dongle attached to it. A few days ago the mouse would not connect so I unplugged moved it to the other port and it worked for a bit. Then it happened again, so thinking it was the mouse I used another air mouse and it worked but failed again (this time got the message unrecognized device after it stopped working). I plugged in a hardwired mouse and keyboard but they do not work (nothing works but there is power coming from the USB port). I opened up the Larkbox and re-sat the cables to the USB board and still nothing. Does anybody have any ideas?
