This motherboard has 4 USB sockets on the rear panel and headers
for another 4, of which two are attached to ports. I've come to
the conclusion:
1. I only have one controller, I can't see any other reason for
the bandwidth problem.
2. Three of the devices do USB 1.1, the disc is the only one doing
USB 2.0 (since it shows up under the high speed controller.
The hub determines if the socket is connected to the USB 2.0 or 1.1
controller, based on the device plugged in. It is possible that both
controllers and the hub are all on the same chip. Because the drive is
the only USB 2.0 device, it will always be connected to the USB 2.0
controller, no matter what socket you plug it into.
Thanks for the feedback, nice to have my suspicions confirmed.
