Just so that you know -- I'm in the middle of submitting one or more patches that do MMIO in ehci-hcd. Once Greg has accepted them you will have to update your patch to change my patch's readl() and writel() calls to ehci_readl() and ehci_writel(). No big deal. There doesn't seem to be anything objectionable in the patch itself. Alan Stern ------------------------------------------------------------------------- Using Tomcat but need to do more?
