I bought a creative zen and the usb ports in my lab top are both damaged so I use a usb hub, it does not work in the hub it will only connect in the port but as the port is damaged it says power surge and it can cut out several times I do not wish to put it in this. Why will it not work in a hub can I do any thing to change this. Also I brought it to put on my computer at work I loaded the software ok but it would not work in the usb there. can you only dock it in the computer that you put it on first or is there some thing wrong with this device. I got it from komplette so I am not sure about tech support any advice please.
