I have a MSI 865 PE motherboard. My front usb connectors JUSB1 and 2 do not recognize my Verbatim USB-2 drive but works with my compact flash(USB-1)reader. It also locks up the usb mouse and keyboard when it's pluged in. The 4 back USB ports work fine with the Verbatim. I can't find any documentation from MSI saying these 2 ports are different than the back 4 ports. By the way Verbatim support was no help either.
