so i bought a 5.25" multifunction panel (card reader, usb hub, audio out). The problem is it doesn't seem to work properly when i plug it onto a motherboard pin usb port (it's supposed to be plugged inside).
The motherboard model is an ASUS P5PE-VM. It has four usb ports on the back. And four internal, two of which are used for the casing's two front panel usb ports.
I tried to plug the multifunction panel via the front panel and it works fine (reads memory cards fine). But it doesn't work properly (yellow triangle w/ an ! warning) when i tried to plug it on to either free motherboard usb pins. Does it have something to do with setting appropriate jumpers for the free pins?
