On my IBM x40 when I connect a usb2 (hi-speed) device (umass(4)) after a
clean boot it attaches to ehci(4) and operates at usb2 hi-speed's. But
after the first suspend-to-disk (Fn+F12) (and all subsequent
suspends/suspend to disk's) it attaches to uhci(4) and operates at usb 1
speeds. This can be seen in the included dmesg where I booted up,
connected the external usb2 hard drive, disconnected it, suspended to
disk, resumed, and reconnected the drive (The laptop was ac powered the
whole time). Just wondering if anyone else has seen this behavior or
can replicate it. I'm using a June 10th snap.
