usb device not recognised on Maximus IV GENE-Z? hi all, I have a Maximus IV GENE-Z (non-Gen3) and I have some problems with using both the onboard front usb connectors. Currently, I am modding the Mac Pro casing and I am trying to connect the USB ports on the apple front panel logic board (2009) to the M4GZ's front panel connectors. Despite following the correct pinout diagram on aquamac forums, the front usb ports doesn't seem to be working. The first time I connected a usb drive to it, the drive's led flashed a few times and there was a popup on windows saying USB device not recognised and Unknown Device in bold in the USB ports list. I;m pretty sure the pinout is correct because prior to this I inserted a male usb plug and used a multimeter to make sure I got the polarity and connections right.
