Pete & Johannes:
This patch causes the uhci driver in 2.4 to wake up the controller when
the root-hub polling loop detects a connect change event. Normally the
wakeup is handled by an interrupt, but it turns out the recent Genesys
Logic GL880S UHCI controller is defective and does not generate the
necessary IRQ. With this patch the controller becomes useable.
Please pass this on to Marcelo.
