I am trying to plug a USB 2 device in a USB 3 slot. Nothing is being 
detected
in "lsusb". Is there something special I need to do? I am running centos 
5.5 x86_64.
I thought 3.0 was backward compatible. Nothing special about my device 
its an RS232 to USB device.
It works in 2.0 slot.

Thanks,

Jerry
