[OpenIndiana-discuss] USB 3.0 weirdness

[russell]

Hi

I have noticed that the USB 3.0 ports on my desktop are working in a 
weird way.

If I plug a USB 3.0 SanDisk Ultra USB 3.0 memory drive into the USB 3.0 
ports then nothing happens and filesystem is not mounted.
However, if I plug in a USB 2.0 memory drive first into one of the USB 
3.0 sockets then plug in the USB 3.0 SanDisk Ultra USB 3.0 memory drive 
will appear.
If I remove the USB 2.0 memory drive from the USB 3.0 socket, the USB 
3.0 drive disappears briefly and then returns.

When I remove the USB 3.0 memory drive from the USB 3.0 and plug it back 
in it will not appear.
However, if I plug the USB 3.0 memory drive into a USB 2.0 socket it 
appears immediately.

Any ideas?

Russell
