I have a Ubuntu 12.04 system. On 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 plug in that USB 2.0 device into the USB 3.0 port, the system gets hung and I try to shutdown but it won't allow me to.
If I continue to match Port types to Device speeds (2.0 to 2.0) everything woks fine.
So my question is: How can I allow a USB 3.0 port to use a USB 2.0 device or is there any way to convert a USB 3.0 port to a USB 2.0 port like drivers or something?
Am I mistaking the issue I'm having for another type of problem?
Here is my
lsub command output
