There was another thread, some time ago, about devices taking power from USB ports without actually being a USB "device" (such as fans and lights), and that being against the specs: Software has to enable more power to the socket. Just taking it, regardless, is asking for failures. There was a change to kernel (I think) behaviour that adhered to the specs (such devices wouldn't get power), to do with reliability, that could be customised to behave the broken way. How this can relate to using external USB disc drives, is when you have one of those with an extra USB plug just for stealing power. That idea is against the USB specs and will be unreliable. -- (Currently running FC4, in case that's important to the thread) Don't send private replies to my address, the mailbox is ignored.
