I believe that I have this very same issue on my Mint 8.0 distro. I have
two 5 port USB 2.0 hubs and only 1 USB port in either device is showing
as a USB 2.0, with all the rest showing 1.1 I've checked the hardware
and every port is supposed to be 2.0

Running a "sudo dmesg | grep usb" swwms to show that all the devices are
recognised as 2.0 but somehow being limited to 1.1:

[156037.796028] usb 10-2: new full speed USB device using uhci_hcd and address 5
[156037.941105] usb 10-2: not running at top speed; connect to a high speed hub
[156037.979263] usb 10-2: configuration #1 chosen from 1 choice

I have not attached a patch, just my Terminal info.


** Attachment added: "USB 2.0 hubs limiting transfer speeds to 1.1"
