Hi all,

On the OMAP3, we have a new hardware bug that causes the
EHCI controller to lock up under heavy stress. The only
known way to recover is to soft-reset the controller.

I'm trying to implement some kind of recovery mechanism
for the ehci-omap driver. Is there a way to inform the
USB core that the root-hub and down-stream devices have
been reset and need to be re-enumerated?

how about you power off all ehci ports, then soft reset it and power on ports again ?
