I have a Epson Stylus Color 740 printer, Logitech WebCam and a HP Scanjet 3300C scanner, all USB. Before I added the HP scanner about 2 weeks ago,I no problems printing with my Epson printer and using the LogiTech Cam. I then added the HP Scanner with required that I add a Belkin USB 4 Port Hub since my motherboard only has 2 usb ports. My problem is that whenever I try to print on the Epson, the printing will start ok, then pause/stop. I have to stop printing activities and try again. I have found that if I unplug the hub (which has the scanner and camera connected) the printer will be ok. Sometimes though, the printing will be ok with everthing connected. I have tried switching around the USB devices but it didn't make any difference. When I do have any devices connected to the Belkin Hub, the hub is dc powered. Would appreciate any help. Bruce

you dont need to have all your USB toys plugged in at the same time. I did following Have the printer plugged permanenetly in the computer USB port and for the second port i bought USB extention cable and i am just plugging into it whatever i need to use. That way i avoided the hassle going behind the computer every time. If you have front side USB you dont need the extention cable. I would return the USB hub and order the extention cable from onvia.com they have free shipping and it is very cheap. Regards Miro
