I'm still using the script that removes the driver and adds it back during the suspend/resume sequence. That seems to be a working work-around for me. That said, I would love to have this fixed for real. Not just for me, but for anyone else that is suffering from the same issue. I'm a kernel developer and can easily include work arounds like this. But for anyone else, this is a total fail for Linux in general. I'm willing to test fixes, as the issue still exists for my laptop if I remove the script. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
