Clearly something is failing when plugging a device with ehci-hcd loaded, the driver seems to keep retrying indefinitely. Instead it would be nice if after a few tries it hands the device over to uhci-hcd. This seems to be the behaviour under Windows, so I was wondering if Linux could be made to do something similar. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
