Hello.
I have 3 identical PC Cases and 1 black that is different.
All the 4 cases have front panel USB ports.
I also have 2 different motherboards:
Intel Desktop Board D845PESV
Gigabyte GA-8IPE1000-G (rev. 3.x)
Every one of them supports USB 2.0 and has front panel USB headers.
Intel motherboard D845PESV works with USB 2.0 ports of every PC Case.
But Gigabyte GA-8IPE1000-G (rev. 3.x) works only with the black case ports...
If I connect it to any of the 3 other cases USB ports and then mount any usb device to it I get "unknown usb device" message...
I have double checked the connections and they are right. I have also tested the usb ports and their cables with my multimeter and they show negligible resistance.
One last thing to mention: The Gigabyte mobo has an external usb bracket that connects to the back side of the case like a PCI card. I swapped it with the front panel USB ports and it still worked while the front ports gave "unknown usb device".
So, what the fuck happens???
