Hi, when I load ohci-hcd first and ehci-hcd second and make sure that the usb-port for the mouse does not share its interrupt with the graphic card, everything works (almost) fine. With big transfers from or to a harddisk in an enclosure the mouse is sometimes a bit jerky.
Bus 007 Device 001: ID 1d6b:0002 Bus 006 Device 004: ID 05e3:0702 Genesys Logic, Inc. USB 2.0 IDE Adapter Bus 006 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB Bus 006 Device 001: ID 1d6b:0002 Bus 005 Device 001: ID 1d6b:0001 Bus 004 Device 001: ID 1d6b:0001 Bus 003 Device 001: ID 1d6b:0001 Bus 002 Device 001: ID 1d6b:0001 Bus 001 Device 005: ID 046d:c518 Logitech, Inc. MX610 Laser Cordless Mouse Bus 001 Device 001: ID 1d6b:0001
bus 1 is ohci. bus 6 is ehci.
But if the mouse is connected to a ehci port or the ehci hub, as soon as data transfers from or to an usb connected storage device starts, it will lock up.
