Make sure the device is actually going to sleep when idle, use powertop to make it happen, that seems to work for me and is probably what Windows does. Otherwise, no, there's nothing that Linux can do here, as a test, try to plug the device into a system like a BIOS/UEFI that does not do any power management and watch it also heat up. I recommend getting a new device, that's what I did :) thanks, greg k-h -- 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
