Hi guys, I have a 24" IMAC (mid 2010) model. Problem is that I tried to connect a USB device like Printer, External HDD or DVD Writer to my mac through a USB hub it just didn't work. But when I connect the devices directly to my MAC, problem solved. Now I'm wondering if my Belkin 6 port travel usb hub is not compatible. Possibly stupid question here but could someone please shed the light?
