Something does not add up here. uhci is for a full speed (or low speed) usb bus, so it runs at 12,000,000 hz in full speed mode. The theoretical maximum transfer rate is around 1 MB/sec. So how are you getting 14 times the possible transmission rate? Ehci has to be involved somewhere, either compiled in or it is already loaded.
