Subject: usb-hub: wakeup on detach too.
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=be35cbbc8802eeba750c300c35339d69929989a6;p=qmiga%2Fqemu.git

usb-hub: wakeup on detach too.

When detaching devices from the usb hub we must wakeup too,
otherwise the host misses the detach event.

Commit 4a33a9ea06f6fbb08d8311a7cfed72975344f9ab does the
same for device attach.
