I have a Ubuntu 12.04 system. To that system I have one USB 3.0 port. In this port I am trying use my USB 2.0 device. But every time when I plugged that USB 2.0 device into that USB 3.0 port,system gets hanged though I tired to shutdown but it won't allow me.
But same type of device I used for USB 2.0 it works fine. So I have a question as " How can allow USB 3.0 port to use USB 2.0 device or did is there any way for converting USB 3.0 port to USB 2.0 port like drivers or something". Here is my lsub command output Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 002 Device 002: ID 8087:0024 Intel Corp.
