Long ago I posted a bug fix for a VIA add on uhci card (plugging in a new
device disconnects existing devices)  The workaround is to suspend the
hc before doing the PORT_RESET for the new device, and wake it up
afterwards.

However this is problematic in 2.5/6: if you suspend the hc, it immediately
wakes up (need for wakeup detected in uhci_irq).  So I need a way to
forceably suspend the hc, so that it only wakes up when I say so.  This
certainly means complicating the existing code in uhci-hcd.  Any comments
and suggestions for the best way to do this before I start hacking?

Thanks,

Duncan.
