other USB hubs on the comp? Prior to adding this printer I was able to use all of the USB hubs available on my computer (4 on the monitor, 2 in the front of the CPU and had the ability to attach an add'l 4 port USB hub...). The new printer w/built in card reader and 1 USB hub took up the resources for the other hubs and now I can only use that one USB hub on the printer. What can I do to fix this? HP doesn't seem to have a clue why their printer has done this. Everything was fine before. And each time I uninstall my hubs go back to working so I know it's the printer drivers.
