lsusb gives
Bus 003 Device 001: ID 0000:0000  
Bus 002 Device 001: ID 0000:0000  
Bus 001 Device 001: ID 0000:0000
but the ports are dead!
i.e adding/removing a usb device is not recognized,
that is, dmesg shows no change and flashdrives etc. are not
seen.
Again this is normal, everything works, after a reboot.
This is a A31 2652-C4U

The A31s are great machines except where suspend/resume is concerned.
