USB 2.0 problem


Hi , i currently using XU4 odroid , i used two 3.0 USB for mouse and keyboard but 2.0 USB don’t seems to be working and i am connecting a wifi module of 2.0 USB compatibility but it don’t seem to be reading my wifi module . when i tried to put wifi module to 3.0 USB it works well . Should i buy a USB 3.0 port hub or is there a way to solve the problem?


Can you post dmesg output?
And usual usb 2.0 port hub will also work on usb 3.0 port. So no need to buy special usb 3.0 hub.
