USB mouse prevents processor power state C3

Hello all,

I'm trying to figure out why the fact that my USB mouse is plugged in prevents
the processor from entering C3 state, the bus-master flag is at ffffffff.

Unplugging the mouse solves the problem. It seems rather strange to me that
this would influence it, since It's not used at all...

I ran across this thread:

Has anyone some more info on it?

Thanks.

Please CC me on answers from linux-usb, i'm not on that mailing list.
