Here is what may be going on: the USB spec requires that plugs make .5 amps (I think) available to devices. Hubs which do not use an external power supply cannot supply that to all the devices on that hub, so they do wonky things. So if you must have a USB hub, get one with an external power source. -- "When we talk of civilization, we are too apt to limit the meaning of the word to its mere embellishments, such as arts and sciences; but the true distinction between it and barbarism is, that the one presents a state of society under the protection of just and well-administered law, and the other is left to the chance government of brute force." - The Rev.
