Keyboard and mouse not working

Hi, i recently got my keymander and was working fine with a few fixable bugs but today i ran into a problem with my keymander. I plugged it in like any other day and noticed my keyboard and mouse werent working, they were on and lighted up like usual, But not working. So i restarted my xbox and then it still was not working. The controller is working and on but they keyboard and mouse are both on in the right placed but not working. Please help, Thanks.
